Cell Cycle and Genetics

A collection of flashcards to help review definitions and concepts related to the cell cycle and genetics.

S-phase

Centromere

The region of a chromosome where sister chromatids are joined together.

Apoptosis

The process of programmed cell death.

Homologous chromosomes

Chromosome pairs, one from each parent, that are similar in shape, size, and genetic content.

DNA polymerase

An enzyme that synthesizes DNA molecules from nucleotides.

46

The total number of chromosomes in a typical human somatic cell.

92

The total number of chromatids present during the S-phase after DNA replication.

Self-fertilization

The fusion of gametes from the same individual to produce offspring.

Replicate
