Question 3

In which stage of the cell cycle are chromosomes replicated?

Answer 3

S phase

Question 4

Which phase of the cell cycle is the longest?

Answer 4

Interphase

Question 5

Which phase of the cell cycle is the shortest?

Answer 5

Mitotic Phase

Question 6

is the preparatory phase

Answer 6

Interphase

Question 7

is the dividing phase

Answer 7

M Phase

Question 8

also called body cells

Answer 8

Somatic Cells

Question 9

what is the difference between somatic cells and gamete?

Answer 9

Somatic- Mitosis/ Diploid cells

Gamete- Haploid Cells

Question 10

define diploid cells

Answer 10

2 sets of chromosomes

Question 11

define haploid cells

Answer 11

1 set of chromosomes

Question 12

How many chromosomes made up a human/?

Answer 12

haploid- 23

diploid- 46

Question 13

A condition in which a child is born with an extra copy of their 21st chromosome

Answer 13

Trisomy 21

Question 14

is the division of a cell into two daughter cells that are genetically identical to the parent cell.

Answer 14

Mitosis

Question 15

form a spindle of microtubules,

Answer 15

Centrioles

Question 16

the chromatin materials start to condense, forming discrete chromosomes. The nucleus and other organelles of the cell start to disintegrate. Centrioles start to move toward the opposite pole

Answer 16

Prophase

Question 17

Metaphase

Answer 17

chromosomes convene on the

metaphase plate

Question 18

What is Metaphase Plate?

Answer 18

an imaginary plane equidistant

between the two poles of the spindle fibers

Question 19

the sister chromatids are separated simultaneously at their centromeres. Spindle fibers will then pull the chromatids toward the opposite poles of the cell. Along with that action is the formation of spindle fibers between the migrating chromatids which causes the cell to elongate

Answer 19

Anaphase

Question 20

The chromosomes have reached the
opposite poles of the cell. The spindle fibers start to disappear. Nuclei and cytoplasmic contents of the daughter cells start to reform.

Answer 20

Telophase
