Question

Are genes in euchromatin expressed?

Answer 1

Genes

1. Genes are the segments of DNA that contain codes for protein synthesis.
2. Hundreds to thousands of genes come together to make up a chromosome.
3. Chromatin refers to a complex of DNA and protein that forms the chromosomes. Histone proteins help in the DNA packing.
4. The loosely-packed region of chromatin is known as euchromatin. It stains lightly compared to the heterochromatin regions. It is found in the inner region of the cell nucleus in prokaryotes and eukaryotes.
5. Genes in euchromatin are expressed. These genes are transcriptionally active.
6. Genes in the euchromatin region can be transcribed. They are the regions where genetic variations occur.
