D)genomic library.

Question

Quizplus · Accepted Answer

Single nucleotide polymorphisms (SNPs) are genetic variations that occur when one nucleotide differs from the typical nucleotide at a specific location in the genome. SNPs are the most common type of genetic variation in humans and other organisms, with some SNPs occurring in at least 1% of the population. Short tandem repeats (B) are another type of genetic variation, but they involve repeated DNA sequences rather than single nucleotide changes. Recombinant DNA molecules (C) are laboratory-created DNA molecules that result from combining DNA from different sources. Genomic libraries (D) are collections of DNA fragments that represent the entire genome of an organism, and they are often used for genome sequencing or other molecular biology experiments.
