What is DNA, and how does it work? You don't need a degree in genetics to understand. Here, we'll give an overview of DNA and ...

Combinations of these atoms form the sugar-phosphate backbone of the DNA -- the ... made along the way -- in other words, that a base pair in one DNA molecule doesn't match the corresponding ...

The sugar-phosphate backbone ... molecule. DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of ...

Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding nucleobases. (Image: Wikimedia Commons, CC SA 3.0) The most common type of base pairing is the Watson-Crick base ...

The double-stranded DNA that results from this pattern of bonding looks much like a ladder with sugar-phosphate side supports and base-pair rungs. Note that because the two polynucleotides that ...

The backbone of the DNA double helix consists of ... This is known as the base-pairing rule. A nucleotide consists of 1 phosphate, 1 sugar and 1 base. Each individual's DNA is unique.

Except for identical twins, each person's DNA is unique. This is why people can be identified using DNA fingerprinting. DNA can be cut up and separated, which can form a 'bar code' that is ...
