Tryptophan is an amino acid necessary for
e. coli survival and growth.
e. coli contain genes coding for enzymes that synthesize tryptophan. these genes are grouped together on a segment of dna called the tryptophan (trp) operon. cells can use these enzymes to synthesize tryptophan when it is not present in the environment. however, when tryptophan is already present in the environment, cellular resources are shifted away from manufacturing the enzymes for tryptophan synthesis. tryptophan binds with and activates the trp repressor, which then binds to the trp promoter and blocks rna polymerase. blocking rna polymerase decreases the normal transcription rate of the operon. what type of regulation does the trp operon exhibit?

Create a sentence explaining how amino acids form proteins.
Sample answer: Amino acids are monomers that combine to form polymers called proteins.
Answer:
Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.
Explanation:
What amino acid does the codon GAC code for ?
The amino acid codon GAC codes for Asx.
Final answer:
The codon GAC corresponds to the amino acid aspartic acid (Asp), and the mRNA sequence 5'-AUGCCACGAGUUGAC-3' translates to the amino acid sequence methionine-proline-arginine-valine-aspartic acid (Met-Pro-Arg-Val-Asp).
Explanation:
The codon GAC codes for the amino acid aspartic acid (Asp). When translating an mRNA sequence, it's important to read the sequence from the 5' end and consider that protein synthesis begins with the N-terminal amino acid. Given the mRNA sequence 5'-AUGCCACGAGUUGAC-3', this translates to the amino acid sequence methionine-proline-arginine-valine-aspartic acid (Met-Pro-Arg-Val-Asp).
It's worth noting that in the genetic code, each triplet of nucleotides, known as a codon, corresponds to a specific amino acid. While most amino acids are encoded by more than one codon, methionine and tryptophan are unique in that they are only encoded by one codon each. The codon AUG not only codes for methionine but also serves as the start signal for protein synthesis.

The waste products of cellular respiration include ______.water and glucosewater onlycarbon dioxide onlyglucose onlywater and carbon dioxide
Cellular respiration produces water and carbon dioxide as its waste products. These are used in photosynthesis for the creation of energy.
Explanation:The waste products of cellular respiration include water and carbon dioxide. During this process, oxygen is used to metabolize, or break down, carbohydrates within the cytoplasm and mitochondria of a cell. The result of this process is the release of energy in the form of ATP, along with byproducts of water and carbon dioxide. This is a part of a larger biological cycle where these byproducts are then used in photosynthesis to create life-sustaining energy.

How does the immune system work with other body systems to prevent and fight disease?
The immune system works in tandem with the rest of the body to prevent and fight any infections and diseases.
All the nucleated cells present in the body, that is all cells except the RBCs have on their surface major histocompatibility complex 1 (MHC 1). Whenever a cell is infected by a pathogen, the antigenic peptides that are synthesized in the cell are represented by MHC 1.
The peptides presented by MHC 1 are recognized by the T lymphocytes and an immune response is elicited.
The skin also acts as a physical barrier and prevents any infection.
The gastric acid secreted by the stomach also kills any pathogen that may have transmitted through food.

The question involves understanding experimental design in Biology, where row 2 of corn without fertilizer acts as the control group in a plant growth experiment.
Explanation:The subject of this question pertains to experimental design in Biology, specifically regarding plant growth experiments. When the scientist applies fertilizer to row 1 but not to row 2, with all other conditions being equal, row 2 serves as the control group.
This control is essential for understanding the effect of the fertilizer on plant growth. In experiments where different variables are tested on their effects on plant growth, such as light exposure, nutrition, or genetic factors, the control group provides a baseline for comparison. The control group's outcome is used to assess the impact of the independent variable being tested, which in the case of the scientist's experiment with corn, is the fertilizer.

An individual has a nutrient deficiency due to a poor diet and is missing a specific amino acid, how would this affect the ability of the cell to synthesize particular proteins?
If an individual is missing a specific amino acid due to a poor diet, it would affect the ability of the cell to synthesize particular proteins, including those in neurons.
Explanation:The individual's neurons would not be able to synthesize proteins. Free amino acids available for protein construction are said to reside in the amino acid pool within cells. Structures within cells use these amino acids when assembling proteins. If a particular essential amino acid is not available in sufficient quantities in the amino acid pool, however, synthesis of proteins containing it can slow or even cease.

Why does a tundra lack trees? A. the animals eat it to quickly B. the permafrost has no soil C. the permafrost ground prevents deep root growth D. the ground is a glacier
The correct answer is C. The permafrost ground prevents deep root growth
Explanation:
Tundra is a biome characterized by cold temperatures, low vegetations (grasses, shrubs, mosses), and a subsoil covered by permafrost, which refers to a subsoil that has a temperature lower than 0° C and may contain ice. This permafrost is responsible for the presence of low vegetation and the lack of high vegetation such as trees, this can be explained as the low temperature along with possible ice prevents deep root growth and this stops trees and similar plants from obtaining nutrients and therefore thrive. According to this, the reason tundra lack trees is that the permafrost ground prevents deep root growth.

D. NADH
2.
A. ATP
B. Carbon Dioxide
C. Water
D. NADH
1. OPTION C
2. OPTION D
In photosynthesis, the electron that travels through the electron transport chain comes from Water. In cellular respiration, the electron comes from NADH.
Explanation:In photosynthesis, the electron that travels through the electron transport chain in the thylakoid membrane comes from Water (C). This process happens in the chloroplasts of plant cells, where light energy is used to break down water molecules, releasing electrons in the process. These high-energy electrons then move through the electron transport chain, contributing to the production of NADPH and ATP, the energy carriers in photosynthesis.
On the other hand, in cellular respiration, a molecule of NADH (D) supplies the electron that travels through the electron transport chain. This process happens in the mitochondria of cells. NADH is an electron carrier produced in the Krebs Cycle, and donates its high-energy electrons to the electron transport chain, leading to the generation of ATP, the cell’s energy currency.

Explanation:
Monkey's (new world) and primates (old world) have distinctly different vision. most monkey's have dichromatic vision, while primates have trichromatic vision.
a. what kind of mutation occurred in the primate lineage to allow the primates to have an extra opsin gene.
Duplication of an ancestral opsin gene occurred in the primate lineage (Old World primates) and subsequent mutations in the new copy resulted in two types of opsin, instead of just one.
Opsins are a group of light-sensitive proteins found in photoreceptor cells (cone cells) of the retina and they are the primary photopigments in primate eyes. Opsins are involved in vision, mediating the conversion of a photon of light into an electrochemical signal, the first step in the visual transduction cascade.
The difference in colour vision between New and Old World primates results from differing arrangements of the photopigment genes on the X chromosome. In Old World primates the three photopigments are required for trichromatic colour vision and they are encoded by two or more X-chromosome photopigment genes and an autosomal photopigment gene. New World monkeys typically have only one X-chromosome pigment gene.
Primates have trichromatic vision and an extra opsin gene that allows them to see a wide range of colors, unlike most other mammals.
Explanation:Primates have trichromatic vision, which means they have three types of cones in their eyes that allow them to see a wide range of colors. This is in contrast to most other mammals, including monkeys, which have dichromatic vision with only two types of cones. The mutation that occurred in the primate lineage to allow them to have an extra opsin gene is called opsin gene duplication.
