Two nitrogen bases are linked together to form the "rungs of the ladder". The four possible nitrogen bases are Adenine, Thymine, Guanine and Cytosine, assigned A, T, G and C. A will always be paired with T, and G with C.
The bases (A, T, G and C) are attached to the five-carbon sugar deoxyribose and a phosphate group, which make up the framework of the DNA molecule.
Nucleotides are found along the sugar-phosphate backbone of DNA, which forms the "twisted ladder" structure of the double helix. They are the building blocks of DNA and consist of a sugar, a phosphate group, and a nitrogenous base.
In you ladder analogy it would be the rungs. About half is each rung is one base (the other half being is pair obviously)
purines, pyrimidines, nucleotides and nitrogen bases.
Adeninine - Thiamine and Guanine - Cytosine pairs.
The sides of the DNA ladder is composed of sugar and phosphate. 4 bases that make up the rungs of the DNA ladder are A, T, G, and C. The shape of the DNA is a double helix or twisted ladder.
what are 4 bases that make up the rungs of the DNA ladder
what are 4 bases that make up the rungs of the DNA ladder
The enzyme helicase separates the nitrogen base pairs, or rungs, of the DNA ladder.
Yes, the rungs of the DNA ladder consist of pairs of nitrogen bases.
They are nitrogen bases.
nucleotitdes
The rungs of the DNA ladder are composed of alternating deoxyribose sugar molecules and phosphate groups.
The base pairs form the rungs of the ladder.
The sequence of the nitrogenous bases, which are the 'rungs' of the DNA 'ladder' are what give DNA its specificity.
