Answer:

A nucleoid is how the hereditary information is carried in prokaryotic cells.

Explanation:

A nucleoid is a prokaryote-specific organelle that contains the genetic information in prokaryotic cells. It is not present in eukaryotic organelles, where the nucleus holds the genetic information.

A nucleoid differs from a nucleus, because it is not surrounded by a nuclear envelope. It is also irregularly shaped.

The nucleoid is not a complex of DNA bound to proteins, the term used to describe a DNA/protein complex is called chromatin.

A nucleoid can be described as how the hereditary information (the DNA) is carried in prokaryotic cells.

Answer:

a) interphase(G2)

Explanation:

The nucleus would contain 6 pg of DNA at the interphase (G2) phase of the cell cycle.

The cell cycle is characterized by tow main phases, namely;

The interphase
The m phase

The interphase is divided into G0, G1, S, and G2 phase respectively while the m phase is divided into prophase, metaphase, anaphase and telophase respectively.

At the S phase of the interphase specifically, DNA is replicated and the amount of DNA in the cell becomes double.

Hence, a cell whose DNA amount ranges from 3 - 6 pg will have exactly 6 pg after the S phase of the interphase, which is G2 phase.

The correct option id a.
