DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

This means that one strand's sugar-phosphate chain runs in the ... another key characteristic of double-stranded DNA is its unique three-dimensional shape. The first photographic evidence of ...

The structure of DNA can also be described as a ladder. The chemical backbones of the ladder are made up of sugar and phosphate molecules that are connected by chemical bonds. The rungs of the ...

Shown here is the structure of naked DNA -- DNA without all of the proteins ... The sides of the DNA ladder consist of a long string of sugar and phosphate molecules, to which the bases are ...

This had helped her deduce that the phosphate part of the ... just like the one before. This way DNA can reproduce itself without changing its structure -- except for occasional errors, or mutations.

In its structure, DNA contains a pattern for producing amino ... Two nucleotides together form a base pair; the sugars and phosphates form a "backbone," along which the base pairs are strung.

In the second step, the AMP is transferred to the 5’-end of the 5’-phosphate-terminated DNA strand to form DNA-adenylate — an inverted pyrophosphate bridge structure, AppN. In this reaction, the ...

Each nucleotide consists of alternating sugar and phosphate sections with one of the four different bases attached to the sugar.

How DNA gets its shape Researchers at the Chambers University ... DNA has two strands — one is made of sugar molecules and the other of phosphate groups. Between these two strands are nitrogen ...

In its structure, DNA contains a pattern for producing amino ... Nucleotides are the combination of a five-carbon sugar, ...
