Satellite DNA is important because it:
shows high degree of polymorphism in population and also the same degree of polymorphism in an individual, which is heritable from parents to children.
does not code for proteins and is same in all members of the population.
codes for enzymes needed for DNA replication.
codes for proteins needed in cell cycle.
As learnt in
DNA fingerprinting -
The technique of DNA fingerprinting was initially developed by Alec Jeffery.
- wherein
He used a satellite DNA as probe that shows very high degree of polymorphism.
Shows high degree of polymorphism in population and also the same degree of polymorphismin an individual, which is heritable from parents to children.
Option 1)
shows high degree of polymorphism in population and also the same degree of polymorphism in an individual, which is heritable from parents to children.
This option is correct.
Option 2)
does not code for proteins and is same in all members of the population.
This option is incorrect.
Option 3)
codes for enzymes needed for DNA replication.
This option is incorrect.
Option 4)
codes for proteins needed in cell cycle.
This option is incorrect.
