Traditionally, the term tachycardia (from the Greek words tachy, meaning fast, and cardia, meaning heart) is used to describe conditions in which the heart rate exceeds the conventional number of 100 beats/min for more than three consecutive beats, either in response to metabolic demand or other stimuli or because of disease. 4 …
WebAug 3, 2024 · Histone acetylation is the addition of an acetyl group, a three-carbon molecule, to a lysine "residue" at one end of a histone molecule. Lysine is an amino acid, and the 20 or so amino acids are the building blocks of proteins. This is catalyzed by the enzyme histone acetyltransferase (HAT). This process serves as a chemical "switch" that … Cytosine (symbol C or Cyt) is one of the four nucleobases found in DNA and RNA, along with adenine, guanine, and thymine (uracil in RNA). It is a pyrimidine derivative, with a heterocyclic aromatic ring and two substituents attached (an amine group at position 4 and a keto group at position 2). The nucleoside of cytosine is cytidine. In Watson-Crick base pairing, it forms three hydrogen bonds
WebJul 15, 2024 · Chargaff's rule, also known as the complementary base pairing rule, states that DNA base pairs are always adenine with thymine (A-T) and cytosine with guanine (C-G). A purine always pairs with a pyrimidine and vice versa. However, A doesn't pair with C, despite that being a purine and a pyrimidine. This rule is named after the scientist Erwin ...
