When a newly formed cell enters into interphase and begins conducting metabolic functions, it is in _____.
Marta_Voda [28]

Answer:

The correct option is b. G1 phase. When a newly formed cell enters into interphase and begins conducting metabolic functions, it is in <u>G1 phase.</u>

Explanation:

The cell cycle comprises a whole series of events or phases that take place in the cell during its growth and division. A cell spends most of its time at the stage called<em> the interface</em>, and during this time it grows, duplicates its chromosomes and prepares for cell division. The cell cycle has different phases, which are called G1, S, G2 and M.

G1 phase is that in which the cell prepares to divide, during this phase, the cell grows rapidly, while performing routine metabolic processes. It also produces proteins necessary for DNA replication and copies some of its organelles in preparation for cell division. A cell normally spends most of its life in this phase. This phase is also known as Gap 1 phase and actively synthesize RNA and proteins.

G0 phase is a period or cycle of a cell where it remains in a resting state, in this phase mature cells that leave the cell cycle are placed.

G2 phase, during this stage, the cell makes the final preparations for its division.
