Lab practical 3 (pt1): mitosis powerpoint

Question 1

The continuity of life is based on the reproduction of cells, or ___

Answer 1

cell division

Question 2

Mitosis cell division results in ___ with identical genetic information, DNA

Mitosis takes place in ___ cells (any cell in the body with the exception of reproductive cells)

Answer 2

daughter cells

SOMATIC

Question 3

Cell division is an integral part of the cell cycle, the life of a cell from formation to its own division​

The mitotic phase (___) is just a small fraction of the cell cycle.

Answer 3

cell division

Question 4

The cell cycle consists of​

___ (M) phase (mitosis and cytokinesis)​

___ (cell growth and copying of chromosomes in preparation for cell division)​

(The majority of the cell cycle is interphase)

Answer 4

Mitotic

Interphase

Question 5

Interphase (about 90% of the cell cycle) can​
be divided into subphases ​

___ phase (“first gap”)​

___ phase (“synthesis”-where DNA is duplicated)​

Each duplicated chromosome has two sister chromatids (joined copies of the original chromosome)​

The centromere is the narrow “waist” of the duplicated chromosome, where the two chromatids are most closely attached​

___ phase (“second gap”)​

Answer 5

G1

S

G2

Question 6
