It is not a DNA base pair itself, it is a DNA nucleotide base. It does however, form a base pair when bonded with adenine.
No , cytosine always pairs with guanine .
thymine
In DNA: Thymine pairs with Adenine. In RNA: Uracil pairs with Adenine.
The base on one strand pair with the base on the other strand, adenine with thymine, and cytosine with guanine, they join together by hydrogen bonds. Parent
Guanine-Cytosine and Adenine-Thymine
Uracil. In normal DNA it would be Thymine, but in RNA Uracil becomes the base pair for Adenine.
Thymine
thymine
Thymine is the complementary base pair for adenine in DNA.
In DNA: Thymine pairs with Adenine. In RNA: Uracil pairs with Adenine.
Adenine pairs with thymine.
The base on one strand pair with the base on the other strand, adenine with thymine, and cytosine with guanine, they join together by hydrogen bonds. Parent
Thymine, and Cytosine matches with Guanine
Guanine-Cytosine and Adenine-Thymine
In DNA the base pairs are Adenine with Thymine and Guanine with Cytosine. In RNA Thymine is replaced by Uracil so the base pairs are Adenine with Uracil and Guanine with Cytosine.
Uracil. In normal DNA it would be Thymine, but in RNA Uracil becomes the base pair for Adenine.
Thymine
Uracil. In RNA Uracil replaces Thymine.
