In DNA, 20-100 base pairs which vary in every human being form ___________.
Options
- AShort nucleotide sequences
- BVariable number of Tandem repeats
- CLarge nucleotide sequence
- DVariable length of ss base pairs
Correct answer
B. Variable number of Tandem repeats
Step-by-step solution
In DNA, a small sequence of 20-100 base pairs is arranged tandemly in many copy numbers.
The copy number varies from chromosome to chromosome in an individual, showing a very high degree of polymorphism.
These repeated sequences are known as Variable Number of Tandem Repeats (VNTRs) or minisatellites, which form the basis of DNA fingerprinting.
Answer: Variable number of Tandem repeats
