A mitosis is cell divisioncalled equational division, where a diploid cell called a mother cell, gives rise to two other daughter cells.
We prepared a list of exercises on mitosis so you can test your knowledge about cell division that multiplies animal body cells.

1) (UFSM) A biochemist measured the amount of DNA in cells grown in the laboratory and found that the amount of DNA in the cell doubled:
a) between the G1 and G2 phases of the cell cycle.
b) between prophase and anaphase of mitosis.
c) during metaphase of the cell cycle.
d) between prophase I and prophase II of meiosis.
e) between anaphase and telophase of mitosis.
2) (FAZU) Among the following sentences regarding cell division by mitosis, one is incorrect. Point it:
a) at metaphase, all chromosomes, each with two chromatids, meet at the equator of the cell in the highest degree of condensation.
3) Mitosis is a process of cell division that can be divided into four stages. Mark the alternative that correctly indicates the steps and the correct sequence in which they occur.
a) Prophase, G1, S and G2.
b) G1, S, G2 and Metaphase.
c) Prophase, metaphase, telophase and anaphase.
d) Metaphase, prophase, anaphase, and telophase.
e) Prophase, metaphase, anaphase, and telophase.
4) (UNIFOR) In unicellular organisms, division by mitosis means:
a) growth.
b) regeneration.
c) recombination.
d) reproduction.
e) gametogenesis.
5) (CES/JF-MG) Among the following sentences regarding cell division by mitosis, one is incorrect. Point it out.
a) It is a very important process for the growth of organisms.
b) Occurs in somatic cells of both animals and plants.
c) The parent cell gives rise to two daughter cells with half the number of chromosomes.
d) At metaphase, all chromosomes, each with two chromatids, meet at the equator of the cell in the highest degree of condensation.
e) The daughter cells are identical to the parent cells.
6) Mark the alternative that completes the sentences below.
I – __________ is a phase marked by the condensation of chromosomes that become progressively shorter and thicker.
II – In __________ the chromosomes decondense and a new nucleus appears around each chromosome set.
III – The __________ begins after the breakdown of the nuclear envelope, which releases the highly condensed chromosomes.
IV – The __________ is the phase in which the sister chromatids separate, pulled to opposite poles by the shortening of the spindle microtubules.
a) Telophase, anaphase, prophase, and metaphase.
b) Anaphase, metaphase, prophase, and telophase.
c) Prophase, telophase, metaphase and anaphase.
d) Prophase, telophase, anaphase and metaphase.
e) Metaphase, prophase, telophase, and anaphase.
7) Which phase of mitosis is characterized by the positioning of chromosomes at the cell's equator?
a) G1.
b) Prophase.
c) Metaphase.
d) Anaphase.
i) Telophase.
8) Regarding the interface, mark the incorrect alternative:
a) during interphase, the chromosomal filaments remain decondensed and distributed inside the nucleus, constituting the chromatin.
b) it is in the interphase period that the chromosomal DNA is in full activity, producing RNA molecules with instructions for protein synthesis.
c) it is also during interphase that the cell grows and that the DNA molecules of the chromosomes are duplicated, preparing the cell for the next division.
d) the interphase is subdivided into three phases: the G1 phase, the S phase, the G2 phase and the gap phase.
e) in interphase the genetic material is in the form of chromatin filaments.
9) We know that at the end of mitosis the cytoplasm divides to form two daughter cells. The process of dividing the cytoplasm is called:
a) prophase.
b) fragmoplast.
c) karyokinesis.
d) cytokinesis.
i) telophase.
10) (FATEC) The handling of radiology equipment involves health risks, and the Technologist in Radiology follows a series of biosafety standards to avoid unnecessary exposure to radiation ionizing.
This type of radiation can damage your cells, causing them to reproduce in a disorderly way and out of control, generating countless new cells through the same process of cell division that occurs in somatic cells. Thus, it only takes a single cell in the body to become damaged and become a cancer cell for a tumor to appear.
This is because the initial cancer cell divides by:
a) mitosis, generating cells with the same number of chromosomes and the same duplication capacity.
b) mitosis, generating cells with half the number of chromosomes, but still with duplication capacity.
c) mitosis, generating cells with twice the number of chromosomes and an even greater capacity for duplication.
d) meiosis, generating cells with the same number of chromosomes and the same duplication capacity.
e) meiosis, generating cells with half the number of chromosomes, but still with duplication capacity.
1 – the
2 – b
3 – and
4 – d
5 – c
6 – c
7 – c
8 – d
9 – d
10 – the
