WebHuntington's disease (HD) is caused by an expansion of cytosine-adenine-guanine (CAG) repeats in the huntingtin gene, which leads to neuronal loss in the striatum and cortex and to the appearance of neuronal intranuclear inclusions of mutant huntingtin. Huntingtin plays a role in protein trafficking … WebWhen cytosine is methylated, the DNA maintains the same sequence, but the expression of methylated genes can be altered (the study of this is part of the field of epigenetics ). 5-Methylcytosine is incorporated in the nucleoside 5-methylcytidine .

Cytosine can be found as part of DNA, as part of RNA, or as a part of a nucleotide. As cytidine triphosphate (CTP), it can act as a co-factor to enzymes, and can transfer a phosphate to convert adenosine diphosphate (ADP) to adenosine triphosphate (ATP). In DNA and RNA, cytosine is paired with guanine. However, it is … See more 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 … See more Cytosine was discovered and named by Albrecht Kossel and Albert Neumann in 1894 when it was hydrolyzed from calf thymus tissues. A structure was proposed in 1903, and was synthesized (and thus confirmed) in the laboratory in the same year. See more • Cytosine MS Spectrum • EINECS number 200-749-5 • Shapiro R (1999).

WebDNA Doubled-stranded DNA (deoxyribonucleic acid) is comprised of four nucleotide bases: adenosine (A), thymine (T), guanine (G), and cytosine (C). Adenosine and thymine form base pairs whereas guanine and cytosine form pairs. The pairs cause the two strands to coil around each other and form a double helix. RNA WebFigure 15.1. The central dogma of genetics. DNA is transcribed into RNA, which is translated into protein. DNA is composed of the nucleotides cytosine, guanine, adenosine, and thymine. RNA is composed of the nucleotides cytosine, guanine, adenosine, and uracil. Protein is composed of amino acids.
