Question

What is the main difference between telophase and cytokinesis?

	A.	The cell is 2n4x in telophase but each daughter cell becomes 2n2x after cytokinesis
	B.	The cell is haploid in telophase but the daughter cells become diploid after cytokinesis
	C.	Telophase contains no dispersed chromatin or nuclear membranes at any time but both are present throughout cytokinesis
	D.	Since telophase is the last part of mitosis, it isn’t seen until after cytokinesis

Answer 1

Telophase = it is the last phase of karyokinesis in Mitosis. After it occurs the cytokinesis.

In Telophase, the single cell has separated the Chromosomes into two or they have moved poles apart and the spindle begun to broke and it broke at the end of Telophase. The cell organelles begin to reappear and the nucleolus also reappear. The cell is diploid but 4x number of Chromosomes also represented as 2n4x. Here, 2n = diploid cell ; and 4x = 4 multiply by x(haploid) Chromosome.

Example = Humans have 2n = 46; so at telophse is represented as 2n 4*23 ----> where 2n = diploid and 4*23 = 4 * haploid number of Chromosomes.

In Telophase the Nucleus division occurs but still the cytoplasm needs to divide to identify the 2 nuclei as separate. In it the Chromosomes are equal to the replicated Chromosomes. If initial or in normal cell it is 2x then after replication of DNA becomes 2*2x = 4x.

Cytokinesis = it is the division of cytoplasm. As it occurs the 2daughter cells are formed and have equal number of Chromosomes as the Parent cell have. It is also represented by 2n2x. Where 2n = diploid cell ; And 2x = 2* haploid number of Chromosomes.

So, the major difference between Telophase and cytokinesis is the number of Chromosomes in the cell. Both phases have diploid cell but the difference lies in their Chromosome number ; in Telophase it is equal to 4x while in cytokinesis it is 2x ( the initial number of Chromosome as parent cell).

So, accordingly the correct answer to question is Option A
