Question

The genetic information of a prokaryotic cell may best be described as:
1. Circular, looped, folded, doubled stranded DNA known as the bacterial chromosome
2. Circular, looped, folded, single stranded DNA known as the bacterial chromosome
3. Circular, looped, folded, double stranded RNA known as the bacterial chromosome
4. Linear double stranded polypeptide

Answer 1

Answer:

2. Circular, looped, folded, single stranded DNA known as the bacterial chromosome

Explanation:

The bacterial chromosome of a prokaryotic cell, does not occur in the typical X chromosome found in eukaryotic cells, but it is a long folded and looped molecule composed of double-stranded supercoiled DNA. In this case, DNA occurs freely and covalently closed in a circular shape in the cytoplasm and it does not bind with proteins.

Answer 2

Answer:

1. Circular, looped, folded, doubled stranded DNA known as the bacterial chromosome.

Explanation:

"Prokaryotic cells lack a defined nucleus, but have a region in the cell, termed the nucleoid, in which a single chromosomal, circular, double-stranded DNA molecule is located.

Archaeal membranes have replaced the fatty acids of bacterial membranes with isoprene; some archaeal membranes are monolayer rather than bilayer."
