Since the 1990s, the term has referred to a type of formal headwear worn as an alternative to the hat; it is usually a large decorative design attached to a band or clip. In contrast to a hat, its function is purely ornamental: it covers very little of the head and offers little or no ...
Histone acetyltransferases ( HATs) are enzymes that acetylate conserved lysine amino acids on histone proteins by transferring an acetyl group from acetyl-CoA to form ε- N -acetyllysine. DNA is wrapped around histones, and, by transferring an acetyl group to the histones, genes can be turned on and off. In general, histone acetylation ...
Histone acetylation and deacetylation are essential parts of gene regulation. These reactions are typically catalysed by enzymes with "histone acetyltransferase" (HAT) or "histone deacetylase" (HDAC) activity. Acetylation is the process where an acetyl functional group is transferred from one molecule (in this case, acetyl coenzyme A) to another.

First Lady Jill Biden is stoking ire from some social media users after wearing a fascinator instead of a hat to Queen Elizabeth II's funeral.
Pilos hat. The pilos ( Greek: πῖλος, felt[ 14]) was a typical conical hat in Ancient Greece among travelers, workmen and sailors, though sometimes a low, broad-rimmed version was also preferred, known as petasos. [ 15] It could be made of felt or leather. The pilos together with the petasos were the most common types of hats in Archaic ...
Genetics is the study of genes, genetic variation, and heredity in organisms. [ 1][ 2][ 3] It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically.
