Deacetylation removes acetyl groups from histone tails, causing the histones to wrap more tightly around the DNA and interfering with the transcription of genes by...
Early embryonic divisions in Drosophila are syncytial. Nuclei undergo mitosis synchronously for the first 14 nuclear cycles, followed by cellularization (Foe and Alberts, 1983). At...
Packaging of DNA into chromosomes is achieved through the nucleosome, the basic chromatin unit. In a nucleosome, the core octamer of histones, composed of two...
Breakthrough in neuroblastoma and breast cancer research identifies new treatment targets
A team of researchers have discovered a completely new pathway in which a cell protein...
Double helix DNA strands wrap up the eight histone proteins to form a nucleosome.
The modification of these histones is one of the mechanisms in epigenetic...
