Answer:
Answer is C.
Explanation:
For A and B, a base substitution affects one of the three bases that comprise a codon, the DNA/RNA unit that corresponds to a particular amino acid. If one base is substituted, one codon and therefore one amino acid will be affected. Codons have built-in redundancy, so even by changing one base, the new codon sometimes still corresponds to the same amino acid. Therefore, a base substitution at most affects one amino acid, and sometimes doesn't affect it all.
Frameshift mutations cause a lot more trouble. These occur when you have a deletion or insertion that changes the number of bases in your gene. As a result, the "frame" of the codons changes (everything shifts one way or the other by the number of bases added/removed). This affects EVERY codon downstream of the mutation, so you can imagine that such a mutation would have a bigger effect the closer to the start of the gene it occurs. This is why C is correct.
A protein's secondary structure is characterized by beta pleated sheets and alpha helices; the primary structure of a protein is the order of amino acids in a polypeptide, which is coded for the DNA of a gene. the secondary structure itself results from Hydrogen bonds, where the electronegative nitrogen and O2 atoms impart the hydrogen atoms with a semi positive charge.
Prion disease is a protein that can affect the brains protein. People can get it through family history or its passed on through the genes, those who ate a cow infected by mud cow disease and infections from medical equipment. I hoped this helped.
<span>Baroreceptors are special receptors that detect changes in your blood pressure. Important baroreceptors are found in the aorta and the carotid sinus. If the blood pressure within the aorta or carotid sinus increases, the walls of the arteries stretch and stimulate increased activity within the baroreceptors.</span>
I would say excretion since that means the process of expelling waste matter.
