Guanine in Biological Definition

Purine

... of the bases in nucleic acids , adenine and guanine , are purines. In DNA , these bases form ... (bases attached to ribose ). Both adenine and guanine are derived from the nucleotide inosine ... phosphoribosyltransferase (HPRT) salvages guanine and hypoxanthine. Genetic deficiency of HPRT ...

DNA

... their bases. These are adenine (A), thymine (T), cytosine (C), and guanine (G). In a DNA double helix, two polynucleotide strands can associate ... next, but that for particular pairs of nucleotides -- adenine and thymine, guanine and cytosine -- the two nucleotides are always present in equal ...

Splicing (genetics)

... Group 1 : do not form lariats but instead bind introns to free-floating guanine ; Group 2 : perform the same two-step chemical reaction as the ... final mRNA product must have each of the following: A 5' cap , a guanine tri phosphate nucleotide, thus named because it binds to the 5' end of ...

Anticodon

... 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. ...

Genetic code

... sugar and one of the 4 nitrogenous nucleotide bases grouped into 2 categories, purine and pyrimidine . The purine bases adenine ( A ) and guanine ( G ) are larger and consist of two aromatic rings . The pyrimidine bases cytosine ( C ) and thymine ( T ) are smaller and only consist of one ...

DNA sequence

... or strand, The possible letters are A , C , G , and T , representing the four nucleotide subunits of a DNA strand ( adenine , cytosine , guanine , thymine ), and typically these are printed abutting one another without gaps, as in the sequence AAAGTCTGAC. This coded sequence is sometimes ...

Double helix

... published by James Watson and Francis Crick in 1953. They showed that DNA is made up of two complementary, antiparallel strands of the bases guanine , Adenine , Thymine , and Cytosine , covalently linked through phosphodiester bonds . Each strand forms a helix, and the two helices are held ...

Nucleoside

... Nucleobase Nucleoside Deoxynucleoside Adenine Adenosine A Deoxyadenosine dA guanine Guanosine G Deoxyguanosine dG Thymine Thymidine T Deoxythymidine dT Uracil Uridine U ...

Nucleotide

... indicates whether the nucleotide in question is a ribonucleotide (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 ...

RNA

... RNA or "RNA genes" 5.3 Double-stranded RNA 6 See also Chemical structure RNA has four different 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 adenine. ...

Wobble base pair

... 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 Nature on Wobble base pair ...
