What happens to rna polymerase ii after it has completed transcription of a gene?

Answers

It is free to bind to another promoter and begin transcription.
Final answer:

After completing transcription, RNA polymerase II is released from the DNA template, and the pre-mRNA undergoes processing to become a mature mRNA molecule.

Explanation:

After RNA polymerase II has completed transcription of a gene, it is released from the DNA template. At this point, the newly synthesized RNA molecule, known as the primary transcript or pre-mRNA, undergoes several processing steps.

The primary transcript is modified by the addition of a cap and a poly-A tail, and introns (non-coding regions) are spliced out to form the mature mRNA. Once these modifications are complete, the mature mRNA molecule can exit the nucleus and undergo translation to synthesize a specific protein.

In summary, RNA polymerase II dissociates from the DNA template after transcription, while the pre-mRNA undergoes processing to become a mature mRNA molecule.

why is stop and start codon signals necessary for protein synthesis ?

Answers

Start codons is necessary for the start of protein at accurate site on mRNA sequence, while stop codon is necessary for termination of protein synthesis. if any of them either start or stop codon attach at inappropriate place in mRNA sequence it will lead to abnormal protein synthesis.

The stop codons and the start codon are fundamental because these codons SPECIFY the length of the resulting PROTEIN SEQUENCE during protein synthesis (translation).

A codon is a triplet of nucleotides in the messenger RNA (mRNA) that determines a specific amino acid, which will be added to the nascent polypeptide chain (i.e., the protein) during translation.

There are 64 codons, 61 of which encode 20 different amino acids, whereas 3 codons specify stop signals that end the process of translation (UAG, UAA, and UGA).

The codon AUG is the first codon in the transcribed mRNA sequence, which encodes the methionine amino acid.

Both start codons and stop codons are fundamental because they indicate where to start and where to finish the process of protein synthesis, respectively.

Final answer:

Forest fire smoke affects large area air quality over many days when favorable wind conditions are present, there are larger fires, and the burning is persistent.

Explanation:

Smoke from forest fires is most likely to affect air quality over larger areas for many days when there are favorable wind conditions, larger fires, and persistent burning. Favorable wind conditions help to disperse the smoke satisfactorily over a vast area, maintaining its presence in the atmosphere for a longer duration. The larger the fire, the more smoke is produced, leading to a more significant impact on air quality over an extensive area. Lastly, persistent burning causes continued production of smoke, hence more extended periods of polluted air.

True. Hemoglobin is the iron-containing compound that carries oxygen in the bloodstream.

What is Hemoglobin?

Hemoglobin is an iron-containing protein found in red blood cells that plays a crucial role in transporting oxygen from the lungs to the various tissues and organs of the body.

It binds to oxygen in the lungs, where oxygen concentration is high, and releases it in tissues with lower oxygen levels.

This process is essential for the delivery of oxygen to cells and the removal of carbon dioxide, a waste product of cellular respiration, from the tissues.

Hemoglobin's ability to bind and release oxygen is facilitated by its iron component, which can reversibly bind to oxygen molecules.

Name two ways in which animal behavior is related to environmental cycles

Answers

If an inherited behavior allows an animal to survive and reproduce, the behavior can spread ... Many animals respond to the cycles in the environment with daily or seasonal cycles of behavior. Hope that helps

Final answer:

Animal behaviors such as migratory patterns and reproductive cycles are aligned with environmental cycles to enhance survival rates.

Explanation:

Animal behavior can be closely related to environmental cycles in various ways. Here, I will name two.

Migratory Patterns: Animals often migrate to exploit resources that are only available at certain times of the year due to seasonal changes. For example, many bird species migrate to warmer regions during winter when food is scarce in their breeding territories.Reproductive Cycles: Many animals time their breeding to coincide with environmental conditions that are favorable for the survival of their offspring. For example, deer may mate in the fall so that the offspring are born in the spring when food is plentiful and weather conditions are milder.

These behaviors ensure the survival of species by synchronizing life cycles with the changing environment.

One method of lessening the environmental impact of strip mining is to -

Answers

Final answer:

To reduce the environmental impact of strip mining, land can be reclaimed for various uses, waste products utilized to create new materials, and bioremediation can neutralize contaminated water. In addition, promoting alternative practices such as minimal tillage can limit further damage.

Explanation:

One method of lessening the environmental impact of strip mining is to reclaim and repurpose the land after mining operations have ceased. Mining often leaves behind vast areas of disturbed land; however, such land can be rehabilitated and transformed into beneficial uses such as airports, landfills, and golf courses. Furthermore, the waste produced from mining operations, such as synthetic gypsum from scrubbers, can be utilized to make products like cement and wallboard, instead of being discarded as waste. This approach not only reduces the amount of waste sent to landfills but also conserves natural resources.

Beyond land reclamation, introducing bioremediation methods is also crucial. The use of bacteria to neutralize acidic water and detoxify chemical by-products from acid mining is an example of using natural processes to restore the habitat, making it suitable for animals and plants. Actions like these help to prevent pollution, save energy, and increase economic security by relying on domestic sources of reclaimed materials.

Lastly, policymakers and activists advocate for alternative mining practices, such as minimal tillage, which can reduce environmental damage while still fulfilling economic needs. Combination of such practices with reforestation and habitat restoration can further stabilize ecosystems and help in recovery of biodiversity.

Plants inherit genes that enable them to produce chlorophyll, but this pigment is not produced unless the plants are exposed to light. this is an example of how the environment can

Answers

Plants inherit genes that enable them to produce chlorophyll, but this pigment is not produced unless the plants are exposed to light. this is an example of how the environment can influence on gene expression.  

Light has an important role in gene expression in plants by producing a number of light-induced changes. One of the examples of the light effects is that chlorophyll and the proteins required for assembling the photosynthetic apparatus are synthesized together with the enzymes needed for carbon fixation. Gene expression influenced by light includes the regulation at the level of transcription or, alternatively regulation of translation.

The correct answer is option 2. The scenario described, where plants have the genetic capability to produce chlorophyll but only do so when exposed to light, is an example of how the environment can influence the expression of a genetic trait.

Environmental factors, such as light exposure, can regulate the expression of genes responsible for producing chlorophyll, demonstrating that the environment plays a crucial role in the manifestation of genetic traits.

Why other options are not correct:

Option 1 is incorrect because mutations are changes in the DNA sequence. The scenario describes the activation of an existing gene by an environmental factor (light), not a change in the DNA sequence itself.

Option 3 is incorrect because the production of chlorophyll in response to light exposure does not lead to the formation of a new species. Speciation is a much more complex process involving genetic divergence and reproductive isolation over many generations.

Option 4 is incorrect because the scenario given does not compare different plant species or their reactions to light. It simply explains how light exposure affects the production of chlorophyll in plants in general.

The complete question is:

Plants inherit genes that enable them to produce chlorophyll, but this pigment is not produced unless the plants are exposed to light. This is an example of how the environment can

(1) cause mutations to occur.

(2) influence the expression of a genetic trait.

(3) result in the appearance of a new species.

(4) affect one plant species, but not another.

A woman frequently has a dinner meal of grilled steak, baked potato with margarine, green peas, and a white dinner roll. which food should be eaten less often to reduce her risk of breast cancer?

Answers

Grilled steak should be eaten less often to reduce her risk of breast cancer. When meats are cooked at high temperatures such as grilling or pan frying, there is production of polycyclic aromatic hydrocarbons and heterocyclic amines which are chemicals that can trigger changes to the DNA and this can increase breast cancer risk.






Final answer:

The grilled steak should be consumed less frequently to reduce her risk of breast cancer due to a correlation between high intake of red meat and increased breast cancer risk. A diet rich in fruits, vegetables, lean proteins, and whole grains is recommended.

Plant roots that grow with mycorrhizal fungi create a mutualistic relationship called mycorrhiza, where the fungi aid in water and mineral absorption while receiving carbohydrates from the plant.

The symbiotic relationship described, where plant roots grow with mycorrhizal fungi, is an example of mutualism, specifically a fungal and plant partnership known as mycorrhiza. The fungi absorb water and minerals from the soil and pass them on to the plant, while in return, the plant provides carbohydrates, produced through photosynthesis, to the fungi. This relationship benefits both organisms as the fungi obtain a steady supply of glucose while the plant increases its nutrient uptake and improves water absorption, thanks to the large surface area of the fungal mycelia consisting of hyphae that effectively facilitate these processes. Phosphorus and nitrogen are two key minerals that are more efficiently absorbed by plants due to the association with mycorrhizae.
