Definitions

100

Binary Fission

The origins of the two newly replicated chromosomes move away from each other and toward opposite ends of the cell

200

n stands for

The different types of chromosomes

300

Diploid

Having two sets of chromosomes

400

Sister chromatids

Two copies of a chromosome that are held together by the centromere

500

Homologous Chromosomes

Two chromosomes that carry the same set of hereditary characteristics

Who does this?

100

Process of binary fission

Prokaryotes

200

Gives homologous chromosomes

1 male parent and 1 female parent

300

Mitosis

Eukaryotes

400

Makes sure cell is not damaged and checks for growth factors

G₁/s checkpoint

500

Meiosis

Eukaryotes

What stage?

100

Replication

S stage

200

Cell growth, normal functions

G₁ stage

300

Yields two identical diploid daughter cells

M stage

400

Cell prepares for division

G₂ stage

500

Where cells function and no division occurs; many cells never enter this stage

G₀ stage

What parts?

100

Interphase

G₁, S, G₂

200

Checkpoints

G₁/s, G₂/M, and spindle assembly

300

Binary fission

Replication of DNA, separation of replicated chromosomes to sides, and cell division

400

Cellular reproduction

Prokaryotes and eukaryotes

500

Mitosis

DNA replication, sister chromatids separate, and cell divides
