Question

Copy number variation (CNV) describes DNA segments of at least ______ in size which exhibit copy number differences among members of ______.

Multiple choice question.
a) 1,000 bp ; the same species
b) 100 bp ; the same species
c) 100 bp ; different species
d) 1,000 bp ; different species

Answer 1

The correct answer is a) 1,000 bp; the same species, describing CNVs as a significant source of genetic diversity within a species.

Step-by-step explanation:

Copy number variation (CNV) describes DNA segments of at least 1,000 bp in size which exhibit copy number differences among members of the same species. CNV can occur through various mechanisms such as deletion, insertion, duplication, or translocation of DNA segments. These variations can impact genetic diversity and contribute to the development of genetic conditions. The correct answer to the multiple-choice question is a) 1,000 bp ; the same species. CNVs are a type of structural variation and can result in deletion, insertion, and duplication of DNA segments. This genetic variation is part of the natural diversity found within populations and has implications for health, disease, and how individuals respond to drugs.
