Chicago: Field Enterprises, 1996. On the average, a single human chromosome consists of DNA molecule that is about 2 inches long.. 2.3 m. The chromosomes in the nucleus of a cell contain all the information a cell needs to carry on its life processes.t is a double-stranded helical macromolecule consisting of nucleotide monomers with deoxyribose sugar and the nitrogenous bases adenine (A), cytosine (C), guanine (G), and thymine (T). In the chromosomes of a cell, DNA occurs as fine, spirally coiled threads that in turn coils around another, like a twisted ladder.
The average distance between base pairs measured parallel to the axis of a DNA molecule is 3.4 Ã. The average molar mass of a pair of nucleotides is 650 g/mol. Estimate the length in centimeters of a DNA molecule of molar mass 5.0 Ã 10 9 g/mol. Roughly how many base pairs are contained in this molecule?
