(Definition of âcentralâ from the Cambridge Business English Dictionary Â© Cambridge University Press)
Other combinations of the atoms form the four bases: thymine (T), adenine (A), cytosine (C), and guanine (G). These bases are the rungs of the DNA ladder. (It takes two bases to form a rung -- one for each side of the ladder.). A sugar molecule, a base, and a phosphate molecule group together to make up a nucleotide.Nucleotides are abundant in the cell's nucleus. Nucleotides are the units which, when linked sugar to phosphate, make up one side of a DNA ladder.ther combinations of the atoms form the four bases: thymine (T), adenine (A), cytosine (C), and guanine (G). These bases are the rungs of the DNA ladder. (It takes two bases to form a rung -- one for each side of the ladder.). A sugar molecule, a base, and a phosphate molecule group together to make up a nucleotide.
A nucleotide consists of three components:   1. A 5-carbon sugar (deoxyribose for DNA or ribose for RNA)   2. A nitrogenous base (adenine, cytosine guanine and thymine (â¦ or uracil in RNA)   3. nucleotide is made of a phosphate, a sugar and a nitrogenous base. In RNA the sugar is ribose and in DNA it is deoxyribose. The bases in DNA are A, T, G and C. The T is repl â¦ aced by U in RNA. 1 person found this useful.
