WebWhen DNA is wrapped around histones, the genes cannot be transcribed into RNA (and, eventually in protein). So these enzymes come along called HATs, which chemically modify the histones in effect loosening their grip on the DNA. This allows the transcriptional machinery access to the DNA, creating RNA (and, eventually, protein).

What is a Chromosome? - News-Medical.net

WebChromosomes are made of DNA, and genes are special units of chromosomal DNA. Each chromosome is a very long molecule, so it needs to be wrapped tightly around proteins for efficient packaging. Near the center of each chromosome is its centromere, a narrow region that divides the chromosome into a long arm (q) and a short arm (p). WebA chromosome is a thread-like structure located in the nucleus of cells such as plant, animal and human cells. Each chromosome is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins. Its unique structure keeps the two DNA strands tightly wrapped around the histone proteins.
