Cell Cycle (Interphase & Mitosis)

Question 1

When a cell undergoes growth & duplication of DNA to prep for next Cell division, & if not actively dividing the cell carry out normal cellular func. (NOT part of Mitosis)

Answer 1

Interphase

Question 2

Cellular contents excluding chromos. are DUPLICATED

Answer 2

G1 phase

Question 3

Each of 46 chromos. is duplicated by cell

Answer 3

S phase

Question 4

Cell “double checks” duplicated chromos for error, makes needed REPAIRS

Answer 4

G2 phase

Question 5

Nuclear division, produce 2 daughter cells, each w/same number & kinds of chromos. as parent cell

Answer 5

Mitosis

Question 6

Chromatin condense to form visible chromos. + Nuclear envelope DISINTENGRATES + Spindle apparatus formas + Nucleolus disappears

Answer 6

Prophase

Question 7

Chromos. align on Metaphase plate

Answer 7

Metaphase

Question 8

Chromos. SPLIT & daughter chromos. migrate to poles + cell ELONGATES, Cytokinesis start

Answer 8

Anaphase

Question 9

Chromos. reach poles, Nuclear envelope reforms + chromos. unwind to Chromatin, Cytokinesis DIVIDES Cytoplasm + Nucleolus REAPPEARS

Answer 9

Telophase

Question 10

(splitting of cells Cytoplasm into 2 parts) DIVIDES Cytoplasm of cell thru a Cleavage furrow/ Cell plate

Answer 10

Cytokineses

Question 11

Made of 2 Chromatids held at center by Centromere

Answer 11

Chromosomes

Question 12

Part of chromo. attached to it w/ a Centromere

Answer 12

Chromatids

Question 13

Constricted pt of the chromo.

Answer 13

Centromere

Question 14

Microtubule-based struct. responsible fro chromo. segregation during Cell division , consists; Asters, Centrioles, Spindle fibers

Answer 14

Mitotic apparatus

Question 15

Pts of radiating fibers at each end (pole) of cell

Answer 15

Asters

Question 16

In middle of Asters

Answer 16

Centrioles

Question 17

Microtubules that attach to chromos.

Answer 17

Spindle fibers

Question 18

Microtubules that attach at the Centromere

Answer 18

Microtubules

Question 19

Area of which chromos. align between poles of cell

Answer 19

Metaphase plate

Question 20

Each Chromatids that sep. at eh Centromere (during Anaphase)

Answer 20

Daughter chromosome

Question 21

Area that starts process of dividing the Cytoplasm, ending as the cell splits into 2 daughter cells

Answer 21

Cleavage furrow
