Nevertheless, some preliminary steps have been taken. Researchers have managed to add some new amino acids to a bacterial cell and were able to make proteins that were one amino acid less than usual.

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...

A new understanding of transfer RNA biology means researchers can assign up to 34 codons to amino acids of their choosing ...

A routine experiment with a new single-cell DNA sequencing method turned into a surprising scientific twist when researchers stumbled upon a bizarre genetic code in a microscopic pond organism.

Scheme showing the structure of cytosine, 5-methylcytosine, and 5-hydroxymethylcytosine. Adding a methyl group to the DNA base cytosine represses gene expression in mammalian cells. To remove the ...

While multiple sclerosis (MS) relapses are manageable with immune-modulatory treatments, the mechanisms behind the progressive stage of this disease are poorly understood. Karolinska Institute ...

A new study shows that long-read sequencing has the potential to improve the rate of diagnosis while reducing the time to diagnosis from years to days -- in a single test and at a much lower cost. One ...

The completion of the Human Genome Project in 2003 set the stage for genetic medicine by revealing the full sequence of human DNA. Reading the entire genome, however, remained costly and too ...

One in every 10 people worldwide is impacted by a rare genetic disease but about 50% of them remain undiagnosed despite rapid increases in genetic technology and testing. Even when a person does have ...
