Rna Operon Diagram


Rna Operon Diagram - the lac operon lactose operon is an operon required for the transport and metabolism of lactose in escherichia coli and many other enteric bacteria although glucose is the preferred carbon source for most bacteria the lac operon allows for the effective digestion of lactose when glucose is not available through the activity of beta galactosidase gene regulation of the lac operon was the transcription is the first step of dna based gene expression in which a particular segment of dna is copied into rna especially mrna by the enzyme rna polymerase both dna and rna are nucleic acids which use base pairs of nucleotides as a plementary language during transcription a dna sequence is read by an rna polymerase which produces a plementary antiparallel rna strand start studying bio chapter 11 homework learn vocabulary terms and more with flashcards games and other study tools the official website.
