Hormones -- such as melatonin and cortisol; the former signals the body to go to bed, while the latter signals for the sleeping person to wake up -- are created by physiological changes.
Answer:
The correct answer is a gene
Explanation:
The DNA segment that carries information for coding one protein or polypeptide is called a gene. According to one gene-one polypeptide hypothesis, each gene is responsible for making a single chain of the polypeptide.
Originally it was said that one gene codes for one enzyme but later it was found that some gene also codes for non-enzyme proteins and single polypeptide chains. So after this research, the theory was modified and one gene-one polypeptide theory came. Therefore the right answer is gene.
Answer:
The most appropriate answer would be The cell will not make functional proteins from that mRNA strand.
The amino acid sequence of the proteins is derived from the nucleotide sequence of the mRNA (messenger ribonucleotide).
If the sequence of mRNA is miscopied, it will change the sequence of amino acids of the protein.
Consequently, the protein may become non-functional.
