what is the base pair rule?

Question

i really dont no?

Answer 1

The DNA double helix is stabilized by hydrogen bonds between the bases attached to the two strands. The four bases found in DNA are adenine (abbreviated A), cytosine (C), guanine (G) and thymine (T).
BASE PAIR RULE:
Each type of base on one strand forms a bond with just one type of base on the other strand. This is called complementary base pairing. Here, purines form hydrogen bonds to pyrimidines, with A bonding only to T, and C bonding only to G. This arrangement of two nucleotides binding together across the double helix is called a base pair. In a double helix, the two strands are also held together via forces generated by the hydrophobic effect and pi stacking, which are not influenced by the sequence of the DNA

The two types of base pairs form different numbers of hydrogen bonds, AT forming two hydrogen bonds, and GC forming three hydrogen bonds

A rule followed by the nucleotides isolated from living cells. Erwin Chargaff, during his studies of nucleic acids, discovered that no matter what the biological source of the DNA, the ratio of the nucleotides obeyed this simple formula:

% Adenine = % Thymine

% Guanine = % Cytosine

This is called as the Chargaff's law, pieces of data of which allowed James Watson and Francis Crick to come up with the double-helix structure of DNA. The ratio arises because in normal cells, nearly all of the DNA is present as a complimentary double-helix, meaning that for each Adenine there is a corresponding Thymine, for each Guanine there is a corresponding Cytosine, and vice versa.

A pairs with T T pairs with A C pairs with G G pairs with C curved letters match up in DNA and straight letters match up. In RNA its a bit different.

Answer 4

Simply, the four nucleotides (bases) that make up DNA - Adenine, Thymine, Guanine and Cytosine - have a special way of linking up.

Adenine only links up with Thymine and vice-versa.
Guanine only links up with Cytosine and vice-versa.

Hence, you only get Adenine-Thymine base pairs and Guanine-Cytosine base pairs.
