Biology (cell growth and division)

G2

Cell grows more to prepare for division

G1

Cells grow and do normal function

Anaphase

Chromatids move toward opposite poles

Metaphase

Chromosomes move to center of cell

Citoconesis

Division of cytoplasm, making 2 cells

Prophase

DNA coils into chromosomes, spindle forms

S phase

DNA is replicated/copied

Telephase

Nuclear envelope re-forms, DNA relaxes

Mitosis

Division of nucleus of cell

Interphase

Entire time between cell divisions, normal cell function

Extra credit : How cell cycle relates to cancer

Because Mutation inside specific genes can lead to loss of balance inside cells, resulting in cancer growth.

Extra credit: Why does s-phase need to be done before mitosis

Because the s-phase is where 🧬 DNA replication takes place

Limits to cell size = ratio of

Surface area to volume

Apoptosis

Planned/programmed cell death

Spindle fiber

Microtubials that help with mitosis

During interphase spindle fibers form the

Cytoskeleton

Polar fibers stretch from

Centriole to centriole, guides through chromosomes by the center structure, the center mirror

Human DNA =

23 pairs

Each chromosome can contain thousands of

Genes

Each cell has a complete set of

Chromosomes for your species

The chromosomes in your body come from
