Eukaryotic Cell division

Question 1

Cell cycle

Answer 1

an orderly sequence of events in the life of a cell from the division of a single parent cell to produce two new daughter cells, to the subsequent division of those daughter cells.

Question 2

animal cell mitosis stages:

Answer 2

1) Prophase
2) Prometaphase
3) Metaphase
4) Anaphase
5) Telophase
6) Cytokinesis

Question 3

Interphase stages:

Answer 3

G0- no growth. Just maintenance

G1- cell growth

S – DNA synthesis

G2 – Cell growth

Question 4

Prophase:

Answer 4

• chromosomes condense and mitotic spindle begins to form

Question 5

Prometaphase:

Answer 5

mitotic spindle fibers attach to kinetochores

Question 6

*metaphase

Answer 6

chromosomes are lined up at the metaphase plate

• each sister chromatid is attached to a spindle fiber originating from opposite poles

Question 7

anaphase

Answer 7

-centromeres split in two

-sister chromatids (now called chromosomes) are pulled toward opposite poles

• certain spindle fibers begin to elongate the cell

Question 8

Telephase

Answer 8

chromosome arrive at opposite poles, decondense, and are surrounded by new nuclear envelopes

Question 9

cytokinesis

Answer 9

The division of cytoplasm following mitosis to form two daughter cells

animal cells:
a cleavage furrow separates the daughter cells

plant cells:
a cell plate: precursor to a new cell wall, separates the daughter cells

Question 10

mitotic spindle

Answer 10

the microtubule apparatus that orchestrates the movement of chromosomes during mitosis

Question 11

Homologous chromosomes

Answer 11

The matched pairs of chromosomes in a diploid organism

Question 12

diploid

Answer 12

(refers to the fact that we have two of each chromosome)

two matched sets of chromosomes contained in a somatic cell

Question 13

nuclear envelope/membrane is made up of…

Answer 13

two lipid bilayer membranes that surround the nucleus
