Researchers developed a reverse translation method that converts protein sequences into DNA, allowing standard DNA sequencers ...

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 ...

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics-meticulously placed chemical tags that influence which genes are expressed in ...

With eDNA metabarcoding, researchers read DNA traces from soil, water, or even air as if they were barcodes. This allows them to discover which plants are or were present, even when they are invisible ...

Proteins, one of the smallest building blocks of life on Earth, hold promise for answering some of biology's biggest ...
