Attenuatorsequence

2022年12月24日 — Attenuator is a nucleotide sequence in DNA that can lead to premature termination of transcription. An example of attenuation is the trp gene in ...

2022年12月24日 — Attenuators are characterized by the presence of stop signals within the DNA sequence that can result in either transcriptional- attenuation or ...

In this attenuation mechanism the regulatory signal is the level of aminoacylated tRNATrp and the sensory event is the efficiency with which the ribosome can ...

A sequence in DNA that is located between the operator and the gene for the first protein in an operon. It can cause transcription termination.
