At a particular location in the human genome is the sequence AATGGAGTC on one of the chromosomes. This sequence occurs in about
ser-zykov [4K]

Answer:

c. AATGGAGTT

d. AATAGAGTC

Explanation:

SNP is a single nucleotide polymorphism. It means that a particular sequence varies among the members of a population with respect to the single nucleotide. The given sequence of the human genome is "AATGGAGTC". The sequence "AATGGAGTT" of option C differs from it with respect to the single nucleotide at the last position (C is replaced with T).

Similarly, the sequence of option D "AATAGAGTC" differs with respect to the nucleotide at position 4 (G in the original sequence is replaced with A). Therefore, these two sequences represent SNP with respect to the given sequence of the human genome.
