The double helix unwinds, and each strand serves as a template for ... with only minor variations in some species. DNA mutations are changes in the nucleotide sequence of the DNA molecule. Mutations ...

Causes: LIG4 syndrome is caused by a mutation in the LIG4 gene ... breaks in both sides of the DNA double helix structure. These kinds of breaks are commonplace, occurring between 10 and 50 ...

When a cell divides, it makes a copy of its DNA instructions for the new cell. The twisted double strand structure -- the famed double helix -- unwinds ... called mutations, but some inevitably ...

In 1953, Francis Crick and James Watson described the molecular shape of DNA as a "double helix." Double-stranded DNA is composed of two linear strands that run opposite to each other, known as ...

Researchers led by Prof. TONG Minghan from the Center for Excellence in Molecular Cell Science of the Chinese Academy of Sciences, collaborating with Prof. HUANG Ying from Xinhua Hospital, Shanghai ...

In 1953, James Watson and Francis Crick proposed the double-helix model of DNA based on X-ray crystallography ... These variations can arise from mutations, which are changes in the DNA sequence of a ...

A new method for mapping torsion provides insights into the ways that the genome responds to the torsion generated by RNA polymerase II.

The signature imagery of two DNA strands locked around each other is one that everyone has seen in school. And, everyone was also taught that the double helix shape with the strands are bound by ...

This new discovery led investigators on a hunt for a "culprit," a genetic mutation ... of this repeated DNA strand—which resides in a gene called CASP8—have more than double the risk (2.2 ...

James Watson (left) and Francis Crick (right) report in Nature the discovery of the double-helix structure of the DNA molecule. Papers from Rosalind Franklin and Maurice Wilkins, which appear ...
