Why is chromatin remodeling necessary for efficient gene expression?

Short Answer

Expert verified

DNA itself can be methylation and that also regulates gene expression, generally to turn off the gene.

Step by step solution

01

Functional RNA.

Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product. These products are often proteins, but in non-protein-coding genes such as transfer RNA or small nuclear RNA genes, the product is a functional RNA.

02

Histones.

Chromatin is the material that makes up a chromosome that consists of DNA and protein. The major proteins in chromatin are called histones. They act as packaging elements for DNA.

Chromatin remodeling plays a central role in the regulation of gene expression by providing the transcription machinery with dynamic access to an otherwise tightly packaged genome.
