Multiple choice

The length of DNA molecule greatly exceeds the dimensions of the nucleus in eukaryotic cell. How is this DNA accommodated within the little sphere of nucleus? (Eukaryotic gene organisation)

  1. Deletion of genes

  2. Through elimination of repetitive DNA

  3. Supercoiling of nucleosomes

  4. DNAase digestion

C Correct answer
Explanation

These are the actual processes of chromosomal packing of DNA within the nucleus. DNA double helix coils around Histone octamers to form nucleosomes and then, the nucleosomes undergo supercoiling to produce more thicker chromatids which are accommodated within the nucleus.
