1
Q

Genome

A

All the DNA in a cell

2
Q

Chromosomes

A

separate DNA molecules that make up the entire genome

3
Q

Homologous Chromsome pairs

A

two different versions of the same chromosome number

-one from mother and one from father

4
Q

Sister chromatids

A

identical, attached copies of a single chromosome

-forming dyads

5
Q

dyads

A

replicated chromosomes containing two sister chromatids that look like an X

6
Q

Kinetochores

A

proteins on the side of centromeres that help microtubules pull sister chromatids apart during cell division

7
Q

Karyokinesis

A

division of the nucleus

8
Q

Cytokinesis

A

physical division of the cytoplasm and cell membrane

9
Q

Parent cell

A

one parent cell produces two daughter cells after division

10
Q

Ploidy

A

describes the number of chromosome sets found in the body

-humans are diploid because they contain two sets of chromosomes

11
Q

Sex chromosomes

A

one pair in the human body and determine sex

12
Q

autosomes

A

22 pairs int he human body and are nonsex chromosomes

13
Q

Gametes

A

haploid cells (sperm and eggs)

14
Q

Germ cells

A

diploid cells that divide by meiosis to produce gametes

15
Q

Gametocyte

A

eukaryotic germ cells that can either divide to form gametocytes or produce gametes

16
Q

Somatic cells

A

body cells excluding the gametes

-diploid in humans

17
Q

Cell cycle in humans

A
