In DNA the nitrogen bases are either purines or pyrimidines.
Adenine (A) and guanine (G) are purines, and thymine (T) and cytosine (C) are pyrimidines.
A pairs with T on the complementary strand, and G with C.
In RNA, A pairs with U (uracil). U is specific for RNA, and T is found only in DNA.

∙ 12y agonitrogenous bases are nitrogen containing organic compounds that has the chemical properties of a base
In dna four types of nitrogenous bases are :
Adenine,guanine ,cytosine,thymine
Adenine and guanine are known as purine bases and cytosine and thymine known as pyrimidine bases
Adenine always pairs with thymine by double hydrogen bond
And cytosine always pairs with guanine by triple hydrogen bond

How many single or lone pair of electrons nitrogen have?
There are 3 unpaired electrons in an isolated nitrogen atom, the nitrogen molecule has none.
Two bases in the DNA molecule?
You must be aware that there are four nitrogen bases - adenine (A), thyamine (T), guanine (G) and cytosine (C) [unlike DNA in an RNA molecule uracil (U) is present instead of cytosine (C)]. Each nitrogen base together with a five carbon sugar molecule (ribose in case of RNA and deoxyribose in case of DNA) and a phosphate group forms a nucleotide [not to be confused with nucleoside - just sugar and base, no phosphate group]. Adenine base pairs with thymine with the formation of two hydrogen bonds and guanine with cytosine using three hydrogen bonds. A base pair consists of two nucleotides paired using the above mentioned hydrogen bonds.
How do bases pair up in DNA replication?
A base pair is two chemical bases bonded to one another forming a "rung of the DNA ladder." The DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
Expain how the nitrogen bases of the DNA ladder pair up?
simple adenine pairs with thymine and guanine pair with cystosine.
In a DNA molecule what base pair could normally be composed of?
iron
What arrangement of two bases in the DNA molecule forms?
Base Pair
Which pair of nitrogen bases will form a bond in a DNA molecule?
The two chains are connected by hydrogen bonding between nitrogen bases to form a long double-stranded molecule.So hydrogen bonding determines which nitrogen bases form pairs of DNA.
What is meant by -base paring- and which base pair with which?
It means which nitrogen base pairs with the other Nitrogen bases: A-t T-a C-g G-c
Which base contains nitrogen?
A Nitrogenous (nitrogen-containing) base is a nitrogen-containing molecule having the chemical properties of a base.It is an organic compound that owes its property as abase to the lone pair of electrons of a nitrogen atom.
How the nitrogen bases pair in a DNA molecules?
The order of the bases in each new DNA molecule exactly matches the order in the original DNA molecule by bringing them together with the original DNA cells.
What type of bond holds the base pair together?
The nitrogen bases are held together by hydrogen bonds.
Two or four nitrogen bases linked together in each double standoff DNA?
Base pair
The category of nitrogen bases that consists of 2 rings is the?
The category of nitrogen bases that consists of two rings is the purines.A nitrogenous base is an organic compound that owes its property as a base to the lone pair of electrons of a nitrogen atom. Notable nitrogenous bases include purines.Purines have two fused rings of carbon and nitrogen atoms.
What is the base term that means base-pairing?
Base pairing refers to the pairing of complimentary nitrogen bases, either during DNA replication, or transcription and translation. In DNA, the bases adenine and thymine pair together, and guanine and cytosine pair together. In RNA, the base uracil takes the place of the base thymine. The bases that pair together are said to be complimentary to each other.
Does an base contain h ions?
Generally hydroxide ions (in the case of inorganic bases) or nitrogen atoms with a lone pair (in the case of organic bases).
What does Nitrogen bases floating in the nucleus pair up with on each half of the DNA molecule?
When a nitrogen bases floating in the nucleus ipair up with the basis on each half of the DNA molecule. Remember that the pairing of bases follows definite rules: A always pairs with T, while G always pairs with C. Once the two new bases are attached, two new DNA are formed.

Which nitrogen bases pair in rna?
Uracil and adenosine.
