Question

Does mRNA replicate heterochromatin or euchromatin?

Answer 1

Euchromatin:

1. The euchromatin is an area of constant size that contains X chromosome homologous sequences, Y-specific repetitive sequences, and all of the Y chromosome's known genes, including the presently known 27 different protein-coding genes or gene families.
2. The area of euchromatin is transcriptionally active and produces mRNA.
