Question 213 of 668
SNPs stand for?
SNPs are single base differences found at specific locations in the genome, occurring at about 1.4 million locations.
Question 214 of 668
DNA Fingerprinting relies on identifying differences in?
DNA fingerprinting exploits the high degree of polymorphism found in repetitive DNA sequences (Satellite DNA).
Question 215 of 668
Satellite DNA is classified into Minisatellites and Microsatellites based on?
Classification is based on the base composition (A:T rich or G:C rich), length of the segment, and number of repetitive units.
Question 216 of 668
VNTR belongs to which class of Satellite DNA?
Variable Number of Tandem Repeats (VNTRs) are a type of Minisatellite DNA.
Question 217 of 668
In DNA fingerprinting, the DNA is separated using?
Gel electrophoresis is used to separate DNA fragments based on their size.
Question 218 of 668
The technique of transferring separated DNA fragments to a synthetic membrane is called?
Southern Blotting is the transfer of DNA to a membrane (nitrocellulose or nylon) for hybridization.
Question 219 of 668
Which of the following is used as a probe in DNA fingerprinting?
A radioactive single-stranded DNA probe complementary to the VNTR sequences is used to detect specific DNA fragments.
Question 220 of 668
Polymorphism in DNA sequence is the basis of?
Polymorphisms (variations) at the genetic level are the foundation for both mapping genomes and identifying individuals via fingerprinting.
