BIO 260- Chromosome Structure
ost living cells,
1. Chromosome: a threadlike structure of nucleic acids and protein found in the nucleus of m
carrying genetic information in the form of genes.
2. Centromere: Region of a chromosome where the two sister chromatids attach
3. The location of the centromere: Shapes of chromosomes are described based on:
4. Metacentric Chromosomes: centromere in the 'middle'S
5. Submetacentric Chromosomes: one arm is somewhat shorter than the other/off of m iddle
1/4
, lose to, but
6. Acrocentric Chromosomes: Describes a chromosome whose centromere is placed very c
not at, one end.
- high/away from the middle
end such that only
7. Telocentric Chromosomes: A chromosome with the centromere more or less at one
one arm is visible.
8. Karyotype: the number and visual appearance of the chromosomes in the cell nuclei of an organism or species.
