Cell Cycle and Cell Division

DNA

stores genetic information in the sequences of its nucleotides. Every cell in our body has genetic material in _ form.

Chromatin

a complex of DNA and proteins where interphase DNA is found. Also dispersed inside the intact cell nucleus during interphase.

Chromosome

highly condensed form of DNA.

Cell Cycle

This describes how cells grow, develop, and reproduce.

Interphase Gap 1

Growth of cytoplasm and doubling of organelles.

Interphase Gap 1

Produces proteins, enzymes, nutrients, and energy.

Interphase Gap 1

Highest rate of protein synthesis.

Interphase Gap 1

Movement of centrioles and centrosomes away.

Interphase S phase

DNA replication occurs, where an existing DNA produces another copy of itself.

Interphase Gap 2

Continued growth and production of materials. Also has protein synthesis but not similar to G1.

Cytokinesis

This is the division of the cell’s cytoplasm.

Cleavage furrow

formed in animal cells.

Cell plate

formed in plant cells.

G1 to S Checkpoint

Damage in the cell’s DNA.

Is the cell large enough with all energy reserved and double organelles.

G2 to M Checkpoint

Environmental conditions favorable for cell division to take place.

Properly replicated DNA.

Presence of DNA damage.

M Checkpoint

Proper attachment of spindle fibers.
