Only the G1 cell will replicate its DNA.C. Only the G0 cell will replicate its DNA.D. Only the G1 cell will start to replicate its DNA, but will stop halfway through the replication and will not reach G2.E. Neither of the cells will replicate their DNA.

Answer:

A, Both cells will replicate their DNA.

Explanation:

During the cell division, cell passes through several phases and divides. Before each phase, the cell has to pass through the checkpoints. At these cell checkpoints, the cell receives the internal and external signals.

When the cell is arrested at G₀ phase, the cell does not divide until it receives a signal to proliferate but when the cell passes the G₁ phase, the cell will divide continuously.

In the given question, if the cells when in their G₀ and G₁ phase receive proliferation signal, the G₀ phase cell will also divide and will replicate it DNA during S phase as G₁ phase cell will do.

Thus, Both the cells will divide their genetic material.

42.
<span>C. So they can move materials from one area of the cell to another quickly

A DNA is made of proteins which was synthesized by ribosomes of the cell to produce protein and these proteins are churned into mRNA and then these mRNA and used to catalyse the DNA production. DNA of a cell in the nucleus is the programmed individuality that controls, manages and organises the entire cell to function and initiate cellular activities.

It is more efficient, thus, to move materials quickly.

A blue moon is an additional full moon that appears in a subdivision of a year: either the third of four full moons in a season, or a second full moon in a month of the common calendar

Explanation:

The Moon can turn blue when there’s a certain amount of dust or pollution in the air. The extra dust scatters blue light, making the Moon appear more blue.
