Between cell divisions, DNA is long and stringy and exists as |
chromatin |
|
DNA makes a _______ of itself before cell division. |
copy |
|
In eukaryotes, the DNA wraps around proteins to make a compact structure called a |
chromosome |
|
The two copies of DNA make up the two identical halves of chromosomes. Each half is called a |
sister chromatid |
|
The two chromatids are attached at a point called a |
centromere. |
|
When the cell divides, each of the two new cells will receive one chromatid from each |
chromosome |
|
Humans have ___ pairs of chromosomes for a total of ___ chromosomes IN EACH CELL’S NUCLEUS. |
