Promoter sequences are DNA sequences that define where transcription of a gene by RNA polymerase begins. Promoter sequences are typically located directly upstream or at the 5' end of the ...

Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a particular cell determine what that cell can do. Moreover, each step in the flow of ...

Genetic switches could play a role in creating complex eukaryotic genetic circuits for programmed cell-free systems or artificial cells.

“This is the most exciting and important paper on big questions about eukaryotic origins and the tree of life in years,” said evolutionary biologist Jeffrey Palmer of Indiana University, Bloomington, ...

New analyses find that divergent transcription, in which one promoter directs the expression of two adjacent genes oriented in opposite directions, is conserved across all domains of life. Jack is a ...
