Cell a has half as much dna as cells b, c, and d in a mitotically active tissue. cell a is most likely in
(a) g1.
(b) g2.
(c) prophase.
(d) metaphase.

(A) G1.

Explanation:

The cell cycle consists of the following stages:

1. G1

2. S (synthesis)

3. G2

4. M (mitosis)            

  4.1     Prophase

  4.2    Metaphase

  4.3     Anaphase

  4.4    Telophase

5. Cytokinesis

During the S phase the DNA replicates and the chromosome number doubles. For the rest of the cell cycle until cytokinesis, the DNA amount will be double that contained before S, in the G1 phase.

(A) G1

Further explanation

all living things on this earth experience their respective cycles. For example a cycle when you are at the bottom, or a cycle when you are experiencing success

What exactly is the cell cycle? The cell cycle is a series of processes that occur in cells. There are 3 stages in 1 interphase that must be passed by a cell. The three stages are Gap 1, Synthesis, and Gap 2. What are the processes in the three stages?

G1

In Gap 1, there is a process of protein synthesis and multiplication of these cell organelles. In addition, cells also begin to grow in this section. Gap 1 is the longest step with a duration of about 11-12 hours. The DNA formed in this section only has 1 copy.

Synthesis

In contrast to Gap 1, there is DNA replication in the synthesis section. The process also takes place shorter, which is only 8 hours. Wow, it turns out DNA can also be replicated, yes! It turns out that not only buildings can be replicated.

G2

In the Gap 2 section, there is an unfinished process of organelle propagation in Gap 1. So there is a continuation of the process of organelle propagation that previously occurred in Gap 1. DNA has also been changed into 2 copies with a duration of 2-4 hours.

Now, after the cell has finished preparing for division, the cell will enter different stages of division, depending on the type of cell. if the body cell, the division that will occur is mitosis division, whereas if the cell is a gamete cell, then what will occur is meiosis division.
