Module 12

Question 1

Cell cycle

Answer 1

A series of phases in the life of the cell through which it grows and divides

Question 2

G1

Answer 2

First growth phase of interphase in the cell cycle when the cells increase in size and make proteins and organelles needed for normal cellular functions

Question 3

Mitosis

Answer 3

A type of cellular division in which a single, diploid, somatic cell is divided into two genetically identical daughter cells.

Question 4

Centromere

Answer 4

A specific section of a chromosome where spindle fibers attach during cell division, point of sister chromatids.

Question 5

G2

Answer 5

Second growth, DNA is checked for errors

Question 6

Sister chromatids

Answer 6

One of two identical copies of chromosomes duplicated the S phase

Question 7

Chromatid

Answer 7

Chromatids are separated from each other during mitosis or meiosis II.

Question 8

Histones

Answer 8

Help chromosomes contrast into chromatin during cell division or decadence after cell division is complete

Question 9

Synthesis

Answer 9

Second phase of interphase in the cell cycle where DNA undergoes replication in preparation for cell division

Question 10

Chromosomes

Answer 10

Tightly coiled form of the DNA protein complex

Question 11

Homologous chromosomes

Answer 11

Chromosomes pair that are SIMILAR. Positions are the same, and may have different alleles

Question 12

Cytokinesis

Answer 12

Separate the daughter cells as a new cell wall.

Question 13

Interphase

Answer 13

Cell cycle when division does not occur.

Question 14

Interphase

Answer 14

Cell cycle when division does not occur.
