The rules for base parings in DNA and RNA, are rather simple purines pair with pyrimidines; adenine pairs with thymine and guanine pairs with cytosine In all cases, purines pair with pyrimidines Specifically in DNA, adenine (a purine) pairs with thymine (a pyrimidine) and Guanine (a purine) pairs with cytosine (a pyrimidine) While in RNA, the same simple rules apply, the only difference being uracil replaces thymine adenine (a purine) pairs with uracil (a pyrimidine) and Guanine (a purine pairs with cytosine (a pyrimidine)
A purine will always pair with a pyrimidine. Examples of purines are adenine (pairs with thymine or uracil) and guanine (pairs with cytosine). Examples of pyrimidines are thymine (pairs with adenine), uracil (pairs with adenine), and cytosine (pairs with guanine).
Yes. Adenine+Guanine, or Cytosine+Thymine; each is a pyrimidine/purine pair.
Adenine always pairs with thymine Cytosine always pairs with guanine.
Adenine pairs with Thymine(Double bond) Guanine pairs with Cytosine (Triple Bond) A & G are purine bases and T & C are pyrimidine bases.
when a purine base only pairs with a pyrimidine
It's not a strand that is replaced, but a nitrogen base, much like adenine. The pyrimidine thymine is replaced by another pyrimidine uracil.
In DNA adenine pairs with thymine. In RNA adenine pairs with uracil.
Adenine(purine)=========thymine(pyrimidine)Guanine(purine)----------------cytosine(pyrimidine)
Thymine and Cytosine are the pyrimidine nucleotides of DNA, while Adenine and Guanine are the purine structures.
In DNA adenine pairs with thymine. In RNA adenine pairs with uracil.
a base containing nitrogen that is found in RNA (but not in DNA) and derived from pyrimidine; pairs with adenine
