Snps contain: a) variable amino acid substitutions and are highly heterogeneous. b) various nucleotides transcribed repeatedly and are homogeneous. c) variable base sequences and are variable in the population. d) variable numbers of tandem repeats and are highly uniform in the population. e) small noteworthy transcribed regions and are lethal genes.

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.
