Question

Helllllp please! Sort the events of the cell cycle into the correct order. (These are all in the wrong order.)

1. Chromosomes form
2. Cytokines
3. Chromosomes line up along the equator
4. Interphase
5. Two new nuclei form
6. Sister chromatids separate

Answer 1

Answer:

1. Interphase

2. Cytokinesis

3. Chromosome form

4. Chromosomes line up along the equator

5. Sister chromatids separate

6. Two nuclei form

Explanation:

The cell cycle comes in 2 phases. There's the

1. Interphase stage

2. Mitotic stage

In the Interphase Stage, there are 3 stages which are:

1. G1 phase

2. S phase

3. G2 phase

After the interphase stage, it moves to cytokinesis or mitosis.

In the mitosis phase, there are 5 stages, which are

a. Prophase

b. Prometaphase

c. Metaphase

d. Anaphase

e. Telophase

A. PROPHASE

This phase is also called the chromosome condensation phase. This is the stage where the 2 chromatids condense at a point called the centromere. When 2 chromatids condense, they form a chromosome.

B. PROMETAPHASE

In this stage, the nuclear membrane disintegrates into small membrane vesicles

C. METAPHASE

In this stage the centrosome pulls the the two chromatids, condensed at the centromere, towards the opposite ends of the cell in order to ensure equitable distribution of chromosome. In other words, it aligns each chromosome formed at the centromere to line up along the equator

D. ANAPHASE

In this stage, two sister chromatids are formed

E. TELOPHASE

Telo is gotten from the Greek word meaning "end". So this is the end phase. In this phase, two nuclear membrane forms around each sister chromatids thereby separating the sister chromatids and forming two nuclei.

Answer 2

The correct steps include: chromosomes form during the Interphase (1 and 4), chromosomes line up along the equator (3), sister chromatids separate (6), two new nuclei form (5) and cytokinesis (2).

• The cell cycle can be divided into an Interphase and a mitotic (M) phase.

• The Interphase can, in turn, be divided in G1, S phase and G2 phase.

• The genetic material (DNA) is replicated during the S phase.

• The M phase can, in turn, be divided into prophase, metaphase, anaphase, telophase and cytokinesis.

• During metaphase, the chromosomes align along the equatorial plate of the cell.

• During anaphase, sister chromatids separate to opposite poles.

• At the final stage of telophase, two new nuclei form around the chromosomes.

• During cytokinesis, the cytoplasm finally divides in order to produce two daughter cells.

In conclusion, the correct steps include: chromosomes form during the Interphase (1 and 4), chromosomes line up along the equator (3), sister chromatids separate (6), two new nuclei form (5) and cytokinesis (2).
