Question

Which are matched correctly?

A. Copy Number Variant - changes in chromosome number between individuals

B. Allele-specific oligonucleotide - PCR primers used to detect simple sequence repeat alleles

C. In/Del - a short oligonucleotide probe that will hybridize to only one allele

D. Single Nucleotide polymorphism - alleles that vary based on number of dri-or-tri nucleotide repeats

E. DNA polymorphism - a DNA sequence that occurs in two or more variant forms

Answer 1

The only correct pair that is given in the above options is of Copy number variant and changes in chromosome number between individuals. In copy number variation, the copy number of a particular gene tends to vary from one person to another. All of the other matched pairs are not explaining the given concept correctly.

Hence, the correct option is (A)

About the incorrect options-

(B) Allele specific oligonucleotides are short fragments of DNA, which are complimentary to variable target DNA. Wrong

(C) It represents the insertion of deletion of nucleotides in genome of an individual.

(D) It represents the polymorphism of a single nucleotide.

(E) It represents different DNA sequence, which are found in an individual or among group or population.

Hope it helps, Good luck !!!!
