The name of the twisted ladder shape of the DNA molecule is called a double helix. This is because it is constructed of two long strands that twist around each other to form a ladder-like structure. Continue Reading. The double helix shape of DNA molecules consists of two rails and steps that link the rails together.
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.NA is often said to have a sugar and phosphate backbone.. Each rung of the ladder is made of two nitrogenous bases linked together in the middle. The length of a DNA molecule is often measured in base pairs, or bpthat is, the number of rungs in the ladder.
