Explore cytosine, a fundamental base in DNA and RNA, its critical role in gene regulation and epigenetics, and its significance in biotechnology and genetic diseases.

DNA aptamers are powerful molecular tools in biosensing, bioimaging and therapeutics. However, a limited understanding of ...

In the middle of the 20th century, accumulating data suggested that DNA carries life’s genetic information. Biochemists around the world raced to determine its structure. The competition led to ...

DNA’s chemical cousin, RNA, was the messenger that carries DNA instructions from the double helix in the cell’s nucleus to ...

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 ...

In 1957, just four years after Francis Crick and other scientists solved the riddle of DNA’s structure—the now famous double ...

Researchers analyze various aspects of gene regulation, among which are the three-dimensional structure of the genome and DNA methylation, which differ for different cell types and play significant ...

A piece that aired on NPR this week about the discovery of DNA's structure neglected to mention the significant contribution of Rosalind Franklin to that scientific milestone.

This is called the Wobble hypothesis. Until now such synonymous changes in DNA were deemed “silent” mutations that did not affect the structure or function of the resulting protein.
