Scientists uncover mystery of DNA methylation

All species mark their DNA with methyl groups. This is done to regulate gene expression, distinguish indigenous DNA from foreign DNA, or to mark old DNA strands during replication. Methylation is carried out by certain enzymes ...

New nucleotide could revolutionize epigenetics

Anyone who studied a little genetics in high school has heard of adenine, thymine, guanine and cytosine - the A,T,G and C that make up the DNA code. But those are not the whole story. The rise of epigenetics in the past decade ...

Regulation of fruit development and ripening by DNA methylation

Recently, scientists from Shanxi Datong University and Chongqing University revealed that SlCMT4, which encodes a DNA methyltransferase responsible for de novo and non-CG methylation, plays an important role in diverse developmental ...
