(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.
DNA is composed of nucleotides, which are composed of a 5-carbone sugar (deoxyribose), a phosphate, and a nitrogenous base (adenine, guanine, thymine, or cytosine abbreviated A, G, T, or C). DNA is composed of two complimetary strands, with complimentary bases matching up through hydrogen bonds. pairs with T, and C with G. DNA is not composed of amino acid or proteins, rather it serves as a set of instructions to combine amino acids into proteins (after it hads been transcribed into RNA the RNA is translated into amino acid sequences for proteins).
