Biology Notes (Part 14) The Cell Cycle

Interphase

Within ________, there are three stages called G1, S, and G2.

Eukaryotic chromosomes

________ are composed of DNA wrapped around proteins called histones. Eukaryotic chromosomes are located in the nucleus.

Telophase

In ________, the nuclear envelope reappears, and chromosomes return to chromatin form.

Prometaphase

In ________, nuclear envelope disappears, and spindle fibers attach kinetochores and begin to move chromosomes.

Cytokinesis

________ is the division of the cytoplasm.

Meiosis

________ produces reproductive cells called gametes.

chromatids

In Anaphase, sister ________ separate and move towards spindle poles.

M-phase

The ________ consists of mitosis and cytokinesis.

Mitosis

________ produces all other cell types called somatic cells.

Metaphase

In __________, chromosomes line up along the metaphase plate in the center of the cell.

S phase

In the _______, DNA replication and cell growth occurs.

G1 phase

In the _______, the cell recovers from precious division.

G2

In the _______, cells that have exited the cell cycle are fully arrested.

Cytokinesis

___________ is the division of the cytoplasm. It results in cells called daughter cells.

Prophase

In ____________, chromatin condenses to form chromosomes, nuclear envelope fragments more, spindle apparatus forms, and centrosomes migrate to opposite “poles.”

cell cycle

The __________ is the sequence of events from cell formation to cell division.

cleavage furrow

A _______ is a constriction formed by an actin ring during cytokinesis in animal cells that leads to cytoplasmic division

cell plate

A __________ forms by Golgi vesicles, forming a temporary structure (phragmoplast) and fusing at the metaphase plate; ultimately leads to the formation of cell walls that separate the daughter cells.
