Question

Bacterial genome consist of
  1. Circular, ssRNA
  2. Circular, dsDNA
  3. Zig-zag DNA
  4. Linear, triple stranded DNA

A
Circular, ssRNA
B
Zig-zag DNA
C
Linear, triple stranded DNA
D
Circular, dsDNA
Solution
Verified by Toppr

The bacteria are the small prokaryotic organisms. These organisms have a circular genome which is wound to form a double-stranded structure. There are ori sites from where the genome breaks and the replication start from this site. There are other extrachromosomal DNA known as plasmids which are circular and double-stranded.
Thus, the correct answer is option B.
