Question
Biology Question on biological classification
Genophore/bacterial genome or nucleoid is made of
A
histones and nonhistones
B
RNA and histones
C
a single double stranded DNA
D
a single stranded DNA.
Answer
a single double stranded DNA
Explanation
Solution
Bacteria has no nuclear membrane hence it is called as nucleoid. The genetic material is referred to as genophore. Genophore is the bacterial chromosome. It has a double stranded circular supercoiled DNA. DNA has about 10,000 genes in E.co/i. Double stranded DNA in bacteria is without histones.
