Summary Introduction

Introduction:

Single nucleotide polymorphism or SNPs are defined by the single nucleotide which is present repeatedly in the DNA sequences that cause genetic variation among individuals in a population.

Answer to Problem 1Q

Correct answer:

Single nucleotide polymorphism is found in DNA. Thereforeoption (a) is correct.

Option (a) is given as “DNA”.

Explanation of Solution

Justify reasons for the correct statement:

Single nucleotide polymorphism is characterized by the occurrence of a single nucleotide at specific positions in DNA. Single polymorphism among the DNA of different individual of same species is primary responsible for the different polymorphic appearance.

Hence, option (a) is correct.

Justify reasons for the incorrect statements:

Option (b) is given as “RNA”.

RNA is a single stranded structure and in the cell it is present in helical form and it does not contain any polymorphic forms. Hence, it is a wrong answer.

Option (c) is given as “plasmid”.

Plasmid is an extra chromosomal closed circular DNA which does not contain single polymorphism. Hence, it is a wrong answer.

Option (d) is given as “siRNA”.

The siRNA regulates the gene silencing in the cell, and does not occurs in polymorphic form. Hence, it is a wrong answer.

Hence, options (b),(c), and(d) are incorrect.

Conclusion

Single-nucleotide polymorphism is used as a genetic marker which indicates genetic variation among individuals in a population.
