Genes exist in most cells. Inside a cell is a long strand of the chemical DNA (deoxyribonucleic acid). A DNA sequence is a specific lineup of chemical base pairs along its strand. The part of DNA ...

From synthetic biology and gene therapy to data storage and biofuel production, the demand for synthetic DNA is rising. (1) Chemicals remove the 5’-hydroxyl protecting group. The nucleosides are rich ...

It coats the DNA and shuts down gene expression on that X. For genes to escape, researchers hypothesize, certain sequences on the X, so-called escape elements, attract proteins that help nearby genes ...

In eukaryotes, DNA is tightly wound into a complex called chromatin. Thanks to the process of chromatin remodeling, this complex can be "opened" so that specific genes are expressed.

Each chromosome contains short sections of DNA called genes. These genes carry the instructions that determine features, such as eye colour, hair colour, blood group and height. Our largest ...

How does a gene, which consists of a string of DNA hidden in a cell's nucleus, know when it should express itself? How does this gene cause the production of a string of amino acids called a protein?

This infographic shows how gene therapy works. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the ...
