If one strand of DNA has the sequence ATGCTTGA, the sequence in the complimentary strand would be

A

TCCGAACT

B

TACGTAGT

C

TACGAACT

D

TAGCTAGT

Text Solution

Verified by Experts

The correct Answer is:
C
In a DNA molecule. A=T (two H-bond)
`C-=G` (three H-bond)
Purine `to ` Adenine (A), guanine (G)
Pyrimidine `to` Cytosine (C), thymine (T) so the complimentary sequence of ATGCTTGA is TACGAACT.
