| Tandem repeat DNA |
| I. is classified as microsatellites and mini satellites. |
| II. normally does not code for any protein. |
| III. shows polymorphism. |
| IV. is used in fingerprinting. |
| Choose the correct option. |
A) I and III
B) I, II and III
C) I, III and IV
D) I, II, III and IV
Correct Answer: D
Solution :
[d] Tandem repeats DNA are the repetitive DNA used for DNA fingerprinting. These do not code for any protein. It is highly repetitive and show polymorphism. It is further classified into multiple copy gene, minisatellites and microsatellites DNA. Thus, option [d] is correct.
