Choose true or false. Each right answer scores 1, and each wrong answer scores -1. Not answered questions score 0.

True False

1) Some cells never divide.

2) The somatic cells of animals can perform meiosis and produce gametes.

3) The number of cell divisions of somatic cells of animals is controlled by other cells of the organism, as well as by the features of the somatic cells.

4) During the cell cycle, G2 ohase takes place before the S phase.

5) The interphase encompasses the G1, S, and G2 phases of the cell cycle.

6) Cells decide to divide or not during G1 phase.

7) Cells that differentiate to carry out a function quit the cell cycle during G1 phase..

8) The progression of the cell cycle is driven by phosphorylation and dephosphorylation processes.

9) Cyclins are proteins only synthesized during the S phase, together with the DNA.

10) During the S phase of cell cycle of eukaryote cells, the replication of DNA starts at one point of the DNA strand.

11) Primers are DNA sequences needed for separate both DNA strands during replication.

12) In animal cells, centrosomes are duplicated during G1 phase.

13) The M phase is the cell cycle stage where cell division happens.

14) The nuclear envelope is disorganized during metaphase.

15) Kinetochoric microtubules contact with chromosome kinetochores.

16) During anaphase, the two centrosomes are duplicated, so there are four centrosomes, and each pair is inherited by one daughter cells.

17) El surco de división es paralelo al eje del huso mitótico.

18) In animal cells, cytokinesis is driven by microtubules.

19) In plant cells, the physical separation of the two daughter cells is by assembling new cell wall between them.

20) In plants, the direction of the grow of an organ is determined by the orientation of the mitotic spindle.

21) This cell is in metaphase.

22) This cell is in prophase.

23) This cell is in anaphase.

24) This cell in prophase.

25) This cell is in metaphase.

26) This cell is in anaphase.

27) This cell is in metaphase.

28) In this image, 3 telophases, 1 metaphase and 1 prophase are observed.
