Some people have one sickle cell gene and one normal gene. They have few defective cells and no symptoms because the sickle cell gene is recessive. How does the human system of reproduction result in people getting one copy of a sickle cell gene and one copy of a normal gene? Describe the process.
Answer:
Explanation:During fertilization the embryo receives half of its genetic information from both parents. If one parent is a carrier or sickle cell their genes would be Aa little a being the recessive gene. When mixed with the other parents gene who does not have sickle cell their genes would be AA. When you make a pun net square the results would be AA,AA,Aa,and Aa. Therefore the offspring would have a 50% chance of being a carrier of sickle cell but not having the actual disease
1. (3 pts) On June 6 at approximately 1 pm, Mrs. Smith, Mrs. Stevenson and Mrs. Jones each
delivered a healthy baby boy at Metropolitan General Hospital. At 1:20 pm the hospital's
fire alarm sounded. Nurses and orderlies scrambled to evacuate patients and the three
babies were rushed to safety. After the danger had passed, the hospital staff was distressed
to find that in the confusion, they had forgotten which baby was which! Since the babies
were rescued before receiving their identification bracelets, there was no easy way to
identify them. Dr. Robinson, head of pediatrics, ordered that DNA profiles be preformed
on the babies and their parents. Your job is to determine which baby belongs to which
parent
Identify the parents of

To determine which baby belongs to which parents in the hospital mix-up scenario, DNA fingerprints of the babies and their parents are compared to find genetic markers that confirm biological relationships. The child must share DNA markers with both parents, and the DNA analysis is used to match these genetic profiles.
Explanation:The question revolves around a scenario where three children were delivered at the same time in a hospital, and due to an emergency, their identities got mixed up. To determine which baby belongs to which parents, DNA profiles of the babies and their parents were compared to establish biological relationships based on genetic markers. By examining the DNA fingerprints of the babies and comparing them to those of the parents, the child's parents can be ascertained. The child must share genetic markers with its parents, as children inherit half of their DNA from the mother and half from the father. During a DNA analysis, specific regions of the DNA are analyzed to detect similarities that are unique to family members.
When dealing with paternity or maternity testing, a match in these genetic markers must be found between the child and the alleged parents to confirm a biological relationship. Modern forensic science often uses this approach to resolve cases of uncertain paternity or identify individuals in scenarios like the hospital mix-up described. DNA analysis is a powerful tool in maternity and paternity testing, used not only for medical and legal cases but also for research purposes.
DNA codes for _______ which determines ________
(a) proteins, peptide bonds
(b) mRNA, tRNA
(c) mRNA, ribosome
(d) protein s, traits
DNA carries genetic information in nucleotidic sequences. This information is translated into proteins that codes for traits. Option D. Proteins - Traits.
What DNA codes for?DNA molecules carry genetic information stored in their nucleotidic sequences. This molecule has information about the whole organism and its functions.
Through protein synthesis, this information is first transcripted into mRNA molecule and then translated into proteins.
mRNA is in charge of taking only sequences that code for a single protein from the nucleus to the cytoplasm, where rRNA and tRNA will build the protein.
What are proteins and what is their function?
Proteins are complex macromolecules formed by a sequence of amino acids. They carry out several functions in the organisms.
They are in charge of most cellular activities and are necessary for the structure, function, and regulation of tissues and organs.
Proteins are in charge of determining traits or features that will be expressed by the individual through its development.
The correct option is D. DNA codes for _proteins_ which determines _traits_.

Final answer:
DNA codes for proteins which in turn determine traits, with the sequence of amino acids in a protein being critical to its function. The process involves transcription and translation with mRNA and tRNA playing key roles.
Explanation:
DNA codes for proteins which determines traits. The process begins with transcription, where DNA's nucleotide sequence is copied into messenger RNA (mRNA). This mRNA then provides the code for the sequence of amino acids in a protein during translation. Proteins are comprised of long chains of amino acids linked together by peptide bonds. The specific sequence of amino acids in a protein dictates its structure and function. Transfer RNA (tRNA) carries amino acids to the ribosome, where they are added to the growing protein chain as dictated by the mRNA sequence.
The correct answer to the question is therefore (d) proteins, traits. Proteins are responsible for carrying out a vast array of functions in cells and organisms, and the traits of an organism can be influenced by the types and functions of the proteins produced as a result of gene expression.
