What are the four nitrogen bases of DNA and how do they pair?

A nitrogen base is a nitrogen-containing molecule having the chemical properties of a base. The four nitrogen bases in DNA are adenine, guanine, cytosine, and thymine. Adenine pairs with thymine, and guanine pairs with cytosine. The four nitrogen bases in RNA are the same as DNA, except that the base uracil replaces thymine, and adenine pairs with uracil instead of thymine.
The four nitrogenous bases in DNA are: adenine, guanine, cytosine and thyamine. The pairs are: A-T and G-C.
  • a-t
  • t-a
  • c-g
  • g-c

DNA replication follows complementary base pairing principle. According to this principle adenine pairs with thymine and guanine pairs with cytosine. n case of RNA, thymine is replaced by uracil.
(see what each base stands for below)
  • a= adenine
  • t=thymine
  • c=cytosine
  • g=guanine




Adenine will always pair up with Thymine and Guanine will always pair up with Cytosine. An example is A(which stands for Adenine) would pair up with ___?___ ? would equal T(which stands for Thymine).
The bases pair by hydrogen bonds. Adenine and thymine pair by two hydrogen bonds and cytosine and guanine pair by three.
Answer


By matching the mRNA strand with the right mRNA strand. Ex: TAC CGC TAT CAG AAA GGT CCG would turn into ATG GCG ATA GTC TTT CCA GGC

In RNA

adenine - uracil
guanine - cytosine

Adenine bonds with thynine and Guanine bonds with cytosine
adenine & thymine

cytosine & guanine

(In RNA, adenine bonds with uracil)
Adenine, Thymine, Guanine, and cytosine for DNA
Adenine, Uracil, Guanine and Cytosine for RNA

Thymine pairs with Adenine and Guanine pairs with Cytosine.
A to T and C to G Adenine and Guanine are purines and Cytosine and Thymine are pyrimidines
Simple, adenine pairs with thymine and guanine pairs with cytosine.
A-t,cg
Adenine pairs with thymine.

Guanine pairs with cytosine.
Hydrogen bonds between the bases A-T has 2 hydrogen bonds, C-G has 3 Hydrogen bonds.
Adenine and Thymine, Guanine and Cytosine.
