Noun
a base containing nitrogen that is found in RNA (but not in DNA) and derived from pyrimidine; pairs with adenine
Source: WordNetA base is attached to the 1' position, in general, adenine (A), cytosine (C), guanine (G), or uracil (U). Source: Internet
Adenine binds with thymine and uracil; Thymine binds only with adenine; and cytosine and guanine can bind only with one another. Source: Internet
Because 5-Fluorouracil is similar in shape to, but does not undergo the same chemistry as, uracil, the drug inhibits RNA replication enzymes, thereby blocking RNA synthesis and stopping the growth of cancerous cells. Source: Internet
At these points, one primer set recognizes DNA with cytosines to amplify methylated DNA, and one set recognizes DNA with uracil or thymine to amplify unmethylated DNA. Source: Internet
DNA is first treated with sodium bisulfite, which converts unmethylated cytosine bases to uracil, which is recognized by PCR primers as thymine. Source: Internet
If the pH of the reaction increases to >10.5, the uracil anion forms, making the reaction go much more slowly. Source: Internet
