Respuesta :
Point Mutation is the source of single nucleotide polymorphisms (SNPs) in the human population.
The correct option is A.
What are single nucleotide polymorphisms(SNPs)?
SNPs , also known as single nucleotide polymorphisms, are the most prevalent form of genetic variation in humans. Each SNP is a variation in a single nucleotide, the basic unit of DNA. In a specific section of DNA, an SNP might, for instance, swap out the nucleotide cytosine (C) with the nucleotide thymine (T).
Which is an example of a SNP?
SNPs, also known as single nucleotide polymorphisms or DNA sequence variants, are brought on by changes to a single nucleotide (A, T, C, or G) in the genome sequence. A SNP, for instance, could transform the DNA sequence AAGGCTAA into ATGGCTAA.
What is point mutation?
When a single base pair is added, removed, or altered in a genome, it is referred to as a point mutation. While the majority of point mutations are harmless, they can also have a variety of functional effects, such as modifications to encoded proteins or changes in gene expression.
SNPs are polymorphisms that result from single point mutations that result in various alleles with different bases at certain nucleotide positions within a locus.
