what is the base pairing?

Question

of
1. DNA
2. RNA

Answer 1

Nucleotide or base pairing :

1. A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) -
C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G) .
The rules of base pairing explain the phenomenon that whatever the amount of adenine (A) in the DNA of an organism, the amount of thymine (T) is the same (called Chargaff's rule). Similarly, whatever the amount of guanine (G), the amount of cytosine (C) is the same.

2. RNA follows the same rules of base-pairing as DNA (with the substitution of Uracil for Thymine),

Answer 2

1. DNA: A pairs with T (T & A, get it? LOL), and G pairs with C
2. RNA: A pairs with U, G with C...but RNA is single stranded, so I assume you mean the base pairing of RNA when making a complementary copy of DNA?

Answer 3

DNA pairs AT and CG -- adenine with thymine, cytosine with guanine. Remember: letters with straight lines go together, letters with curves go together.

In RNA, substitute U for the T. Uracil pairs with adenine, cytosine with guanine.
