RNA Interference RNA interference (RNAi) is a form of post-translational modification which occurs in the cytoplasm RNAi is sequence-specific silencing of gene expression and therefore can b...
Epigenetics & Disease Inheritance of epigenetic modifications Epigenetic imprinting is the DNA methylation of certain genes and it occurs during the formation of oocytes and sperm cells ...
Epigenetics DNA is wrapped around histone proteins which form a nucleosome. Nucleosomes coil tightly around each other to form the chromosome structure. In eukaryotic cells, th...
