Question

What is Histone?

Hint:

Histones are essential for DNA condensation and play a key role in gene expression regulation through modifications.

Answer 1

Step 1: Understanding Histone.
Histones are a group of basic proteins found in the nuclei of eukaryotic cells. They play a critical role in the packaging of DNA into structural units called nucleosomes. Histones help in the regulation of gene expression by enabling or inhibiting the accessibility of DNA to the transcription machinery.

Step 2: Conclusion.
Thus, histones are proteins that assist in DNA packaging and gene regulation.
