The bases in a DNA double helical chain are paired A-T and C-G. The A and T bases are bound by 3 hydrogen bonds per pair, and the C and G bases are bound by three hydrogen bonds per pair.

What enzyme joins the nucleotides of a DNA strand together?
That depends on the process. During DNA replication, The nucleotides of the lagging strand (Okazaki fragments) are connected by DNA ligase. In transcription, the nucleotides of RNA are connected by RNA polymerase II.DNA Polymerse
What is a basepair?
A basepair is a pair of nucleotides on opposite complementary DNA or RNA strands which are connected via hydrogen bonds.
How many strands of nucleotides are in DNA?
Thousands upon thousands. Because DNA must contain all the characteristics of your being, it must be long.
How many DNA molecules are in a chromosomes?
There is one double helix DNA molecule per chromosome.
What are the building blocks of DNA and RNA?
NucleotidesNucleotides are the monomers, building blocks, of nucleic acids (DNA and RNA). Each nucleotide includes three components: a phosphate, a sugar, and a nitrogenous base. The phosphate is bonded to the sugar through phosphodiester bonds and makes up the backbone of the molecule. The nitrogenous bases form the "rungs" of the ladder and are connected through hydrogen bonds. The phosphate is the same in DNA and RNA, but the sugar can be a ribose (for RNA) or a deoxyribose (for DNA). The latter is a ribose without "de-" one oxygen "-oxy-". There are four available nitrogenous bases in a DNA's nucleotides: adenine, thymine, guanine, and cytosine. RNA nucleotides feature the same bases with the exception of uracil, which replaces thymine. See related links and questions below.
Why does DNA have to have hydrogen bonds?
The hydrogen bonds between complimentary nitrogen bases hold the two strands of DNA nucleotides together.
What holds DNA bases together?
The bonds of the atom are covalent where as the bonds between the base pairs are hydrogen.
What type of bonds make p DNA and where in DNA do you find these bonds?
The bonds are called hydrogen bonds. You can find these bonds in the nucleotides of DNA.
What are the nucleotides in DNA joined by?
peptide bonds
What nucleotides can be held together by weak hydrogen bonds?
DNA contains four nucleotide bases, which are adenine, thymine, cytosine and guanine. The pairs of nucleotides that can be held together by weak hydrogen bonds are purines and pyrimidines.
What bonds hold together DNA?
hydrogen bonds hold DNA together
What bond is between nucleic acids?
In producing a strand of DNA the nucleotides combine to form phosphodiester bonds.
Where does Helicase attach to on the DNA strand?
Enzyme helicase unwinds the DNA by breaking the bonds between nucleotides. Thus attaches itself at the nucleotides.
What type of bond is between nucleotides?
In producing a strand of DNA the nucleotides combine to form phosphodiester bonds.
In DNA base pairs are held together by what kinds of bonds?
DNA base pairs are held together by Hydrogen Bonds. Adenine and Thymine have 2 bonds that hold them together while Cysteine and Guanine have 3 bonds that hold them together. The hydrogen bonds generally occur between a Nitrogen and a carbonyl oxygen.
What bond DNA forms a double helix?
The base pairs are held together by hydrogen bonds.
The four types of nucleotides that make up DNA are named for their?
hydrogen bonds
