Eukaryotic chromosomes are linear molecules of DNA that are compacted during cell division (mitosis or meiosis)
Each chromosome has a constriction point called a centromere, which divides the chromosome into two sections (or ‘arms’)
Eukaryotic species possess multiple chromosomes that may differ in
In the nucleus of a human cell, there are 23 types of chromosomes. Males would have an additional type, the Y chromosome. There are 22 autosomes and 2 types of sex chromosomes.
Each chromosome has a constriction point called a centromere, which divides the chromosome into two sections (or ‘arms’)
- The shorter section is designated the p arm and the longer section is designated the q arm
Eukaryotic species possess multiple chromosomes that may differ in
- Size; number of base pairs
- Which genes they carry
- Sequence of nitrogenous bases
- Location of the centromere
- Banding pattern when stained
