Study Notes
Cellular Reproduction
- DNA exists in a chromosome form between cell divisions
- Chromosomes form during cell division
- DNA coils tightly around proteins
- Half of a chromosome is called a chromatid
- The constricted area of each chromatid is called the centromere
- The centromere holds chromatids together until cell division
- Humans have 46 chromosomes
- Sex chromosomes determine sex
- Females have XX chromosomes
- Males have XY chromosomes
