Question

Eukaryotic cells multiply as a result of the cell cycle. During the interphase portion of the cell cycle, cells undergo two Gap phases,

known as the G1 and G2 phases. The G1 and G2 phases of the cell cycle are critical to cells because -

O they allow the cell to grow and develop.

O they allow time for the DNA to replicate in the nucleus.

O the cell needs this time to break down the nuclear membrane.

O all cells are given time to perform photosynthesis.

Answer 1

They allow the cell to grow and develop.

Initially in G1 phase, the cell grows physically and increases the volume of both protein and organelles. In S phase, the cell copies its DNA to produce two sister chromatids and replicates its nucleosomes. Finally, G2 phase involves further cell growth and organisation of cellular contents.

Answer 2

the correct answer is O they allow the cell to grow and develop.

Step-by-step explanation:

During the cell cycle, eukaryotic cells go through a series of phases to multiply and produce new cells. The interphase is the longest phase of the cell cycle and is divided into three subphases: G1, S, and G2.

The G1 phase is the first gap phase, where the cell grows and carries out its normal functions. During this phase, the cell increases in size and synthesizes proteins necessary for its growth and development. The G1 phase is crucial because it allows the cell to accumulate the necessary materials and energy for DNA replication in the subsequent S phase.

The S phase is the synthesis phase, where DNA replication occurs. During this phase, the cell duplicates its DNA to ensure that each daughter cell receives a complete set of genetic information. The DNA replication process is essential for cell division and the transmission of genetic material to the next generation of cells.

After the S phase, the cell enters the G2 phase, which is the second gap phase. During this phase, the cell continues to grow and prepares for cell division. It synthesizes additional proteins and organelles to support the division process. The G2 phase is critical because it allows the cell to ensure that it is ready for mitosis, the final stage of the cell cycle.

In summary, the G1 and G2 phases of the cell cycle are critical because they allow the cell to grow and develop. The G1 phase provides time for the cell to accumulate necessary materials and energy, while the G2 phase prepares the cell for cell division. These phases are essential for the proper progression of the cell cycle and the production of new cells.
