The genes lacZ, lacY and lacA are transcribed from a single promoter (P) that produces a single mRNA from which the three proteins are translated. The operon is regulated by Lac repressor, the product ...

COLD SPRING HARBOR, N.Y. (Wed., Jan. 2, 2008) – This month’s release of Cold Spring Harbor Protocols highlights methods that permit scientists to observe protein dynamics in chromosomes and embryos.

The tRNA3 Leu gene from yeast contains an intervening sequence of 32 nucleotides not present in mature tRNA. This sequence is transcribed and subsequently removed during the maturation of the RNA. To ...

Gene-expression events are intricately linked — and there is now a way to view the complete set of events together in a single living cell. Reporting in Cell, David Spector and colleagues have ...

Aranan Tarih Aralığı: 2025-9-23 / 2025-09-24 Aranan Kelime: the likely outcome from a mutation in the laco site lac operator of the lac operon would be multiple choice binding of the activator protein ...
