有關分子生物學英文翻譯!!

Acetylation of histones controls access of regulatory proteins to the DNA.

Access to eukaryotic DNA involves moving or restructuring the nucleosomes – chromatin remodeling.

Methylation of DNA is often used to control gene expression (mostly silences) during development of higher organisms.

Genes are silenced by methylation of the DNA followed by removal of acetyl groups from the histones

Genetic imprinting in eukaryotes has its basis in DNA methylation patterns

The DNA of inactivated X chromosomes is highly condensed – Barr bodies.

Update:

X-inactivation involves the Xist gene and Xist RNA
