Nonhistone protein

Generally involved in controlling the activity of certain regions of the DNA

2

Chromatid

Chromosomes that have two identical halves

3

Centromere

The point where two chromatids of a chromosome are attached

4

Sex chromosomes

Chromosomes that determine the sex of an organism

5

Autosomes

All chromosomes in an organism that deals with size, color and shape

6

Diploid cell

Have two autosomes for each homologous pair.

7

Haploid cells

Haploid cells are sperm and egg Cells

8

During cell division the DNA in the eukaryote cell is tightly packed and coiled into structures called

Chromosomes

9

Between cell divisions the DNA in a eukaryotic cell is uncoiled and spread out in this form it is called

Chromatin

10

The chromosomes of most prokaryotes consist of proteins and

A single circular DNA molecule

11

13

What role do you proteins play in the Enabling the huge amount of DNA in the eukaryotes out to fit into the nuclear us and what are these proteins called

Homologous chromosomes are similar in with they are the sane size and snap and carry genes for the same trait

14
