Question

what is the constituents of chromosomes​

Answer 1

The major chemical components of the chromosome are DNA, RNA (nucleic acids), and proteins (histones and nonhistones).

Answer 2

DNA, RNA, Histone, and Non-Histone proteins constitute the chromosomes.

• Chromosomes are thread-like structures that are present inside the nucleus of a cell and carry the genetic material.
• They are formed by elaborate packaging and folding of the nucleosomes (in eukaryotes).
• Nucleosomes are formed of histone proteins and DNA.
• Nucleosomes are packaged using non-histone proteins.
• RNA is also present in small amounts in the chromosomes.
• The chromosomes condense at the time of cell division causing the chromatin fibers to form compact chromosomes.
