A molecule of DNA consists of two strands that form a double helix structure DNA is a macromolecule consisting of two strands that twist around a common axis in a shape called a double helix The double helix looks like a twisted ladder—the rungs of the ladder are composed of pairs of nitrogenous bases ( base pairs ), and the sides of the ladder are made up of alternating sugar molecules1/3/ · The double helix describes the appearance of doublestranded DNA, which is composed of two linear strands that run opposite to each other, or antiparallel, and twist together Each DNA strand within the double helix is a long, linear molecule made of smaller units called nucleotides that form a chain3 In a doublestranded DNA molecule, what is the relationship between AG and CT, and Suppose that a nonsupercoiled DNA molecule is composed of 4,800 base pairs How many helical turns are 480 turns of the helix are present (4,800 bases at 10 bases per turn) The molecule would be 1632 um long (480 turnsX34A/turn
