NEETZoologyMolecular Basis of Inheritance
Select the correct statement for the given figure.
Options
- ASatellite DNA sequences normally code for proteins and they form a large portion of human genome.
- BThese sequence show low degree of polymorphism and form the basis of DNA fingerprinting.
- CSince DNA from every tissue, from an individual shows the same degree of polymorphism, they become a very usef
- DAs the polymorphisms are not inheritable from parents to children, DNA fingerprinting is the basis of paternit
Correct answer
C. Since DNA from every tissue, from an individual shows the same degree of polymorphism, they become a very usef
Step-by-step solution
The bulk DNA forms a major peak and the other small peaks are referred to as satellite DNA. Depending on base composition (A : T rich or G:C rich), length of segment, and number of repetitive units, the satellite DNA is classified into many categories, such as micro-satellites, mini-satellites etc. These sequences normally do not code for any proteins, but they form a large portion of the human genome. These sequences show a high degree of polymorphism and form the basis of DNA fingerprinting. Since DNA from every
