DNA molecules have a consistant width of about 2.5 nanometers (a nanometer is one billionth of a meter; human hair has a thickness of roughly 20,000 nm to 180,000 nm), but the length of DNA molecules varies greatly. Scientists usually describe the length of DNA using a unit called kb or kbp. One kb is 1000 base pairs, the base pair being the basic repeating nucleotide unit of the DNA chain. Each base pair has a length of 0.33 nm. Plasmid DNA might have a length of 1-200 kb, or 0.33 nm to 66 nm. Bacterial chromosomal DNA length would be perhaps 3800 kb, or 1300 nm (1.3 microns). The length of human chromosome number 1 DNA is 200,000 kb, or 67,000 nm (67 microns). Of course, within the cell, DNA is coiled into a ball much smaller than its length.
Would some smart person answer this question, please.
Really small
About the size of two nanometers
The sides of the DNA ladder are alternating deoxyribose (sugar) molecules and phosphate molecules. The DNA bases attach to the sugar molecules.

Thymine
By the size of the DNA molecule. longer DNA molecules move slower, and shorter DNA molecules move faster!

DNA Molecules
DNA helicases are proteins, while DNA molecules are nucleotides.
Daughter moloqules are newer than DNA moloqules
DNA replication begins in areas of DNA molecules are called origins of replication.

DNA are replicator molecules. DNA molecules are able to male copies of themselves in a process called DNA replication. RNA molecules however, are synthesized using a DNA template through a process called transcription

Two double stranded DNA molecules are created by the process of DNA replication.
The sides (uprights) of the DNA molecule are composed of alternating deoxyribose sugar molecules and phosphate molecules.
