Discover how CRISPR genome editing is revolutionizing medicine. Learn the science of Cas9, current clinical trials, and the ...

Epigenetics is the study of various heritable alterations that control gene expression without changing the DNA sequence. 1 The name epigenetics comes from the Greek prefix “epi”, which means on top ...

Researchers have determined whether a specific chemical modification of a protein that packages the genome called a histone affects gene activity and cell proliferation. Researchers have determined ...

An understanding of the origin and dynamics of heritable genetic variation within classical animal breeding programs is needed to provide the context for understanding the contributions and concerns ...

A recent study led to the development of a powerful epigenetic editing technology. The system unlocks the ability to precisely program chromatin modifications at any specific position in the genome, ...

DNA can also be demethylated, either through passive or active processes. Passive DNA demethylation occurs when the methylation pattern is not replenished during DNA replication and gradually ...

Researchers demonstrated how Mycobacterium tuberculosis modifies its DNA and regulates both replication and gene activity through a reversible process known as ADP-ribosylation. This is the first time ...

Genetic research across multiple studies now points to a clear pattern: populations living in the Andes highlands for ...

Christine Dunham is a leading expert on the ribosome—an elaborate macro-molecular machine that operates like a factory within ...
