Uracil in a sentence

The bases form hydrogen bonds between cytosine and guanine, between adenine and uracil and between guanine and uracil.

Therefore, cells now use uracil in RNA and not in DNA because RNA is more short-lived than DNA and any potential uracil-related errors do not lead to any lasting damage.

This can lead to a point mutation if not repaired by the DNA repair enzymes such as uracil glycosylase, which cleaves a uracil in DNA.

Uracil in DNA Uracil is rarely found in DNA, and this may have been an evolutionary change to increase genetic stability.

When elemental fluorine is reacted with uracil, 5-fluorouracil is produced. 5-Fluorouracil is an anticancer drug ( antimetabolite ) used to masquerade as uracil during the nucleic acid replication process.

A base is attached to the 1' position, in general, adenine (A), cytosine (C), guanine (G), or uracil (U).

Adenine binds with thymine and uracil; Thymine binds only with adenine; and cytosine and guanine can bind only with one another.

Apparently, there was no evolutionary pressure to replace uracil with the more complex thymine in RNA.

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.

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.

Chemical structure of uridine Uracil readily undergoes addition to ribose sugars and phosphates to partake in synthesis and further reactions in the body.

DNA is first treated with sodium bisulfite, which converts unmethylated cytosine bases to uracil, which is recognized by PCR primers as thymine.

However, it is inherently unstable, and can change into uracil ( spontaneous deamination ).

RNA uses uracil in place of thymine.

The deficiency in folate leads to increased ratio of deoxyuracilmonophosphates (dUMP)/deoxythyminemonophosphates (dTMP) and uracil misincorporation into DNA and eventually low production of DNA.

The first site of ionization of uracil is not known.

The general RNA structure is very similar to the DNA structure, but in RNA the nucleotide uracil takes the place that thymine occupies in DNA.

The most common way to synthesize uracil is by the condensation of maleic acid with urea in fuming sulfuric acid as seen below also.

The presence of uracil indicates lactic acid bacteria contamination of the fruit.

The reactivity of uracil remains unchanged, even if the temperature changes.
