Uracil in Biological Definition

RNA

... to each pentose ring; as well as by the use of uracil , instead of thymine . One of the main functions ... bases: adenine , guanine , cytosine , and uracil . The first three are the same as those found in DNA, but uracil replaces thymine as the base complementary to ...

Anticodon

... inosine which allows that base to pair with cytosine , adenine , and uracil on the codon. The first base on the anticodon can also have a uracil which can base pair with guanine as well as adenine. ...

Wobble base pair

... modified base is inosine which can basepair with three bases including uracil , adenine , and cytosine . Another critical base pair is the G-U base pair which allows uracil to base pair with two bases: guanine and adenine . Links ...

Genetic code

... bases cytosine ( C ) and thymine ( T ) are smaller and only consist of one aromatic ring. In RNA however, thymine ( T ) is substituted by uracil ( U ) and the deoxyribose is substituted by ribose . Overall, there are 4 3 = 64 different codon combinations. For example, the RNA sequence ...

Growth curve

... to the toxic effects that conventional anticancer drugs have on the cancer cells . Many conventional anticancer drugs (for example, 5-Fluoro uracil ) interfere with DNA replication and can cause the death of cells that attempt to replicate their DNA and divide. A rapidly growing tumor will have ...

Nucleoside

... Deoxyadenosine dA Guanine Guanosine G Deoxyguanosine dG Thymine Thymidine T Deoxythymidine dT uracil Uridine U Deoxyuridine dU Cytosine Cytidine C Deoxycytidine dC Nucleosides are glycosylamines made by ...

Nucleotide

... (r) or deoxyribonucleotide (d). The second letter indicates the nucleobase: G: Guanine A: Adenine T: Thymine C: Cytosine U: uracil not present in DNA, but takes the place of Thymine in RNA The third and fourth letters indicate the length of the attached phosphate chain ...

Purine

... their complementary pyrimidines thymine and cytosine . purine pyrimidine A T G C In RNA , the complement of A is uracil instead of thymine: purine pyrimidine A U G C Adenine Guanine These hydrogen bonding modes are ...

Pyrimidine

... nitrogen atoms at positions 1 and 3 of the six-membered ring. Three nucleobases found in nucleic acids , namely cytosine , thymine , and uracil , are pyrimidine derivatives. In DNA and RNA , these bases form hydrogen bonds with their complementary purines . purine pyrimidine A ...
