Our long-dreamt-of project on understanding the effects of widely varying tRNA gene copy number is finally complete! In a new paper, we describe the growth consequences of altering redundancy in the bacterial translation machinery. We find that the costs and benefits of redundancy vary with the possible growth rate, i.e. it is nutrient-driven. This was... Continue Reading →
New paper: Evolutionary effects of non-genetic inheritance
Laasya’s single-author review on how non-genetic changes can contribute to evolution is now out in Current Genetics! Transfer of information in biology usually occurs from nucleic acids to protein, but not vice-versa (The Central Dogma). Any molecular alteration that does not change the DNA sequence (genotype) is generally short lived, and is thought to have... Continue Reading →
