Report Abuse. There are about 25,000 base pairs in one human DNA molecule (one double-helix), however some animals have DNA that is 2,000,000 base pairs long. One DNA molecule is made up of two polynucleotide strands that form a double-helix using hydrogen bonds between the nitrogenous bases. A chromosome is one DNA molecule.
A DNA nucleotide is one of two kinds of bases... a pyrimidine or a purine. The purine is a heterocyclic (two-ring) molecule with a 5 member and 6 member ring each containing 2 â¦ Nitrogens.Purines are just a single ring with 2 Nitrogens.Each base is paired with a sugar (ribose) less one oxygen (hence the prefix de-oxyribose).here are four nucleotides that make up DNA: Adenine, Thymine, Guanine and Cytosine. There are billions of them that make up one strand of DNA. Adenine always pairs with Thymi â¦ ne and Guanine always pairs with Cytosine.
