Superimposed on the genetic sequences coding for amino acids is a second genetic code. This second genetic code, which makes use of dual-use codons, or duons, specifies how genes are controlled. The ...
LA JOLLA, CA—One of modern biologists’ most ambitious goals is to learn how to expand or otherwise modify the genetic code of life on Earth, in order to make new, artificial life forms. Part of the ...
Despite the highly conserved nature of the genetic code, the frequency of usage of each codon can vary significantly. The evolution of codon usage is shaped by two main evolutionary forces: mutational ...
Cells working with an expanded genetic code could make more diverse medicines. A new study shows scientists are within striking distance. One of modern biologists' most ambitious goals is to learn how ...
“In a recent study published in PNAS, Sidi et al. (7) leverage an mBART-based (multilingual Bidirectional and Auto-Regressive Transformer) deep-learning approach (Fig. 1) to decode the evolutionary ...
A hidden and never before recognized layer of information in the genetic code has been uncovered by a team of scientists, thanks to a new technique called ribosome profiling, which enables the ...
