Bacterial Enzyme Keeps Rotifers’ Transposable Elements in Check
Christie Wilcox | Mar 3, 2022
Jumping genes in bdelloid rotifers are tamped down by DNA methylation performed by an enzyme pilfered from bacteria roughly 60 million years ago, a study finds.
Mapping Neuronal Gene Expression to Understand Pain
