Here we present the crystal structure of MutS in complex with a 30-base pair (bp) DNA oligomer with a G·T mismatch at position 9. The non-conserved 53 amino acids at the carboxy terminus were ...

DNA is a biological molecule that contains the instructions an organism needs to function, develop, and reproduce. It is present in all forms of life on earth and contains each organism’s ...

James Watson and Francis Crick revealed the structure of DNA — the genetic instructions in all living things — 70 years ago in the journal Nature. Watson and Crick could not have succeeded ...

He and a colleague proved a theory advanced by the Nobel Prize winners James Watson and Francis Crick, who discovered DNA’s ...

The Discovery of DNA's Structure: They were hardly modest, these two brash young scientists who in 1953 declared to patrons of the Eagle Pub in Cambridge, England, that they had "found the secret ...

In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

Find out how the structure of DNA was discovered by Francis Crick and James Watson, and why the discovery revolutionized science and medicine ...

Structure: DNA consists of two strands, arranged in a double helix. These strands are made up of subunits called nucleotides. Each nucleotide contains a phosphate, a 5-carbon sugar molecule and a ...

Inside almost every cell in your body is a structure called the nucleus. This is the control centre of the cell. Inside the nucleus are 23 pairs of chromosomes. These are long strings of DNA. DNA ...

Researchers Valerii Plotnikov and Dan Fisher slice a sample from 52,000-year-old mammoth skin. The skin provided the first ever look at the 3-D structure of the extinct animal’s DNA.
