Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The hereditary material present in the bacterium Escherischi coli is
A
single stranded DNA
B
deoxyribose sugar
C
double stranded DNA
D
single stranded RNA
Explanation: 

Detailed explanation-1: -Thus, the correct answer is ‘Double-stranded DNA.

Detailed explanation-2: -coli is bacteria and comes under Prokaryotes. The genetic material of prokaryote is a single molecule of double-stranded circular DNA molecule and is in direct contact with cytoplasm due to lack of nuclear membrane.

Detailed explanation-3: -A bacterial genomic DNA resides inside cells in a highly condensed and functionally organized form called nucleoid (nucleus-like structure without a nuclear membrane). The Escherichia coli chromosome or nucleoid is composed of the genomic DNA, RNA, and protein.

Detailed explanation-4: -The single-stranded DNA-binding protein (SSB) of Escherichia coli is involved in all aspects of DNA metabolism: replication, repair, and recombination.

Detailed explanation-5: -coli, a bacteria (prokaryote), has circular dsDNA as its genetic material.
