Answer: C) variable base sequences and are variable in the population.
Explanation:
Single nucleotide polymorphisms (SNPs) result from mutations point and correspond to the position where there is an alternation of nucleotides A, C, G, T at a minimum allele frequency of 1% in a given population. The SNPs may be present in both coding and non-coding regions of the genome. In coding regions, when resulting in an amino acid substitution, they are called synonyms and can be conservative or non-conservative depending on the characteristics of the amino acids involved in the exchange. In such cases, modifications may occur in structural and functional proteins.
