How are the bases in RNA paired with the bases in DNA?

Answer 1

First of all, the only RNA, that attaches to DNA is mRNA (messenger RNA), and it matches,

Adenine from DNA and Uracil from RNA;

Thymine from DNA with Adenine from RNA;

Cytosine from DNA and Guanine from RNA;

Guanine from DNA Cytosine and from RNA.

* Also, mRNA complements the left half of DNA, for example if DNA's left half was

(A = adenine, T = thymine**, G = guanine, C= cytosine, U = Uracil**)

**Uracil is found only RNA

**Thymine is found only in DNA

A

T

G

G

C

A

T

Then mRNA would be:

U

A

C

C

G

U

A

so overall

DNA : mRNA

A : U

T : A

G : C

G : C

C : G

A : U

T : A

Answer 2

Adanine pairs with uracil and guanine pairs with cytosine
