Cell Cycle and Division

Question 1

It is a part of the chromosome that links sister chromatids.

Answer 1

Centromere

Question 2

It is a part of the chromosome where the spindle fibers attach during cell division to pull sister chromatids apart.

Answer 2

Kinetochore

Question 3

It is a single strand of chromosome.

Answer 3

Chromatin

Question 4

These are multiple strands of chromatin.

Answer 4

Chromatid

Question 5

These are the steps in Interphase. (4)

Answer 5

Gap (G) 0, G1, Synthesis, G2 (all numbers are subscripts!)

Question 6

This step is for all that don’t divide like brain cells and RBC.

Answer 6

G0

Question 7

In this step, cells manufacture proteins, ribosome and mitochondria for preparation of DNA replication. Also, cells increase in size.

Answer 7

G1

Question 8

In this step, enzymes replicate the DNA.

Answer 8

Synthesis

Question 9

This step is for synthesizing proteins that prepares cell for cell division.

Answer 9

G2

Question 10

It is the process of nucleus division in which replicated chromosomes separate and form 2 daughter cells with nuclei, genetically identical with each other. This division is for somatic or non-sex cells.

Answer 10

Mitosis

Question 11

This is the cell division for gametes or sex cells. It divides twice.

Answer 11

Meiosis

Question 12

These are the phases of mitosis. (4)

Answer 12

Prophase, Metaphase, Anaphase, Telophase.

Question 13

In this phase, chromosomes become visible, nucleolus disappear, spindle fibers form and attach to the chromosomes at the centromere.

Answer 13

Prophase

Question 14

In this phase, spindles of microtubules align the chromosome in the middle of the spindle.

Answer 14

Metaphase

Question 15

In this phase, centrioles split and pull the chromosome toward opposite poles.

Answer 15

Anaphase

Question 16

In this phase, chromosomes arrive at opposite poles, spindle fibers dissolve, nuclear envelope reappear, cleavage furrow develop at the center, and preparatory events are reversed.

Answer 16

Telophase.

Question 17

It is the division of cytoplasm.

Answer 17

Cytokinesis

Question 18

This is the division of nucleus.

Answer 18

Karyokinesis

Question 19

This is the result of Mitosis

Answer 19

2 daughter cells with identical sets of chromosomes.

Question 20

These are the phases of Meiosis.

Answer 20

Meiosis I and II

Question 21

This phase of Meiosis results to 2 daughter diploid cells. It also has PMAT.

Answer 21

Meiosis I

Question 22

This phase of Meiosis results to 4 daughter haploid cells. It also has PMAT.

Answer 22

Meiosis II

Question 23

This occurs during Meiosis I. It is based on the law of Independent Assortment.

Answer 23

Crossover
