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

Answer 1

The four bases of RNA are adenine guanine cytosine and uracil. (Uracil is only found in RNA) The four bases of DNA are adenine, guanine, cytosine and thyamine (thyamine replaces uracil in DNA). The bases in uracil are denoted A, G, C and U. When RNA pairs with DNA, A of the DNA always pairs with U of the RNA, T of the DNA always pairs with A of the RNA, and C and G always pair with each other. If you look at a drawing of each molecule, it is easy to see that each pair of complementary bases are perfectly matched for each other. The bases pair with each other through hydrogen bonding. This is a very strong type of bond that occurs between a hydrogen and an electronegative atom (such as F, O or N). The bases are cyclic structures of carbons and hydrogens, and they have some N-H groups and carboxylic groups. So the bases of RNA pair with their complementary bases in DNA by hydrogen bonding between the N-H groups on one base with the oxygen of the carboxylic group on the complementary base.

Answer 2

The four bases found in RNA (ribonucleic acid) are adenine (A), guanine (G), uracil (U), and cytosine (C).

Adenine always pairs up with uracil in RNA (and vice versa), and guanine always pairs up with cytosine (and vice versa).

A=U

U=A

G=C

C=G

Answer 3

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
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.
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.

Answer 4

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.
