What are chromosomes?

  • Each cell's nucleus contains chromosomes, which are structures that resemble threads and contain the DNA molecule.
  • Each chromosome is constructed from DNA that has been tightly wound around proteins called histones numerous times to support its structure.
  • When a cell is not dividing, chromosomes cannot be seen in the nucleus, not even under a microscope.
  • However, during cell division, the DNA that makes up chromosomes gets more compactly packed and becomes visible under a microscope.
  • The majority of what scientists understand about chromosomes comes from studying them during cell division.

Normal chromosomes:

Humans typically have 46 chromosomes, or 23 pairs of them, in each cell. The appearance of twenty-two of these pairs, known as autosomes, is the same in both sexes. Males and females have different 23rd pair sex chromosomes. Males have one X and one Y chromosome, while females have two copies of the X chromosome.

Hence A normal human male has 44 autosomes, 1 X chromosome and 1 Y chromosome.
