Study Notes
Chromosome
- A chromosome is a thread-like structure composed of DNA and proteins that carries genetic information.
- Each chromosome contains many genes, which are the units of heredity.
Centromere
- The centromere is the region of a chromosome where two sister chromatids are joined.
- It plays a crucial role during cell division, ensuring correct chromosome separation.
Chromatid
- A chromatid refers to one half of a duplicated chromosome, joined at the centromere.
- Chromatids become individual chromosomes once the cell divides, during the anaphase stage of mitosis.
Chromosome (Reiteration)
- Chromosomes ensure the transmission of genetic material during cell division.
- They exist in pairs in diploid organisms, with one chromosome inherited from each parent.
