Question

Explain the significance of satellite DNA in DNA fingerprinting technique.

Answer 1

Significance of satellite DNA in DNA fingerprinting A DNA satellite is a region that consists of short DNA sequences repeated many times. The variation between individuals in the lengths of their DNA satellites forms the basis of DNA fingerprinting.

Answer 2

Significance of satellite DNA:

• Satellite DNA is DNA sequences that cover greatly repetitive DNA which means that a single sequence is repeated many times over.  
• The dissimilarity between individuals in the lengths of their DNA satellites forms the root of DNA fingerprinting.
• This polymorphism of DNA which is used in DNA fingerprinting is used to generate DNA profiles of individuals.
