The single stranded DNA of phage phixx17...

The single stranded DNA of phage `phixx174` has 5400 nucleotides. If average protein contains 200 amino acids, how many different proteins could this phage DNA code?

A

100

B

90

C

9

D

27

Text Solution

Verified by Experts

The correct Answer is:
C
5400 nucleotides in DNA will form 5400`-:`3=1800 codons.
200 aminoacids, i.e., 200 codons form one protein and therefore, `1800-:`200=9 proteins can be formed.
