The thick, thread-like structures in the nucleus that are formed during cell division are called chromosomes. Chromosomes are significant because they contain the genetic material DNA, and transfer it across generations.
- Cell division is mainly composed of four stages: prophase, metaphase, anaphase, and telophase.
- During Interphase, the chromatin(a collection of DNA and proteins) is loosely held in the nucleus.
- In Prophase, the condensation of chromatin leads to the formation of chromosomes essential for the transfer of the genetic material during cell division.
