In the technique of DNA fingerprinting, the specific type of satellite DNA that shows a very high degree of polymorphism and was initially used as a probe by Alec Jeffreys is known as:
Options
- AExpressed Sequence Tags (ESTs)
- BVariable Number of Tandem Repeats (VNTRs)
- CSingle Nucleotide Polymorphisms (SNPs)
- DBacterial Artificial Chromosomes (BACs)
Correct answer
B. Variable Number of Tandem Repeats (VNTRs)
Step-by-step solution
Alec Jeffreys initially developed the technique of DNA fingerprinting. He used a specific type of satellite DNA as a probe that shows a very high degree of polymorphism. This satellite DNA is known as Variable Number of Tandem Repeats (VNTRs).
Expressed Sequence Tags (ESTs) are used to identify all the genes that are expressed as RNA.
Single Nucleotide Polymorphisms (SNPs) refer to single base DNA differences.
Bacterial Artificial Chromosomes (BACs) are used as vectors for cloning large DNA fragments.
