Bacterial Enzyme Keeps Rotifers’ Transposable Elements in Check
Christie Wilcox, PhD | Mar 3, 2022 | 5 min read
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.
Carl Woese In Forefront Of Bacterial Evolution Revolution
Lisa Holland | May 13, 1990 | 4 min read
For the better part of this century, microbiologists have largely ignored evolutionary relationships among bacteria. But a revolution has occurred in microbiology with the advent of nucleic sequencing: Today, new phylogenetic relationships can be determined in far more detail and depth than was ever thought possible. Carl R. Woese, 62, of the department of microbiology at the University of Illinois in Urbana, is widely considered the leader of this revolution. His 1987 review, "Bacterial evolu
