Our collaborative work (with Shashi Thutupalli’s lab at NCBS) on tracking mistranslation-induced phenotypic variability is now published! Protein sequences often differ because of underlying differences in DNA sequence (i.e. genetic mutations). However, making mistakes while building the protein can also introduce differences in the protein sequence, although at a low frequency. Proteins altered in this... Continue Reading →
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 →
Our work on ‘useful’ mistakes in bacteria (E. coli) is finally out! Laasya and Parth found that making rebel proteins not encoded by our DNA can be a good thing. In cells that frequently make mistakes, the accumulated ‘junk’ proteins end up triggering a high alert situation. This allows the cells to better deal with... Continue Reading →
