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.
DNA is a very large molecule, made up of smaller units called nucleotides that are strung together in a row, making a DNA molecule thousands of times longer than it is wide. Each nucleotide has three parts: a sugar molecule, a phosphate molecule, and a structure called a nitrogenous base.The nitrogenous base is the part of the nucleotide that carries genetic information, so the words nucleotide and base are often used interchangeably.The bases found in DNA come in four varieties: adenine, cytosine, guanine, and thymineoften abbreviated as A, C, G, and T, the letters of the genetic alphabet.ach nucleotide has three parts: a sugar molecule, a phosphate molecule, and a structure called a nitrogenous base.
