WebO The mutation will have no effect on transcription of the trp operon. The trp operon will be transcribed, unless tryptophan is supplied in the medium. A missense mutation in one of the enzymes encoded by the trp operon prevents a bacterial cell from producing tryptophan. What is the effect (if any) of this mutation on transcription of the trp ... WebTranscription is initiated by the attachment of a protein known as a sigma. The sigma attaches to one strand of the DNA (the template strand) at a very specific location. In …
WebSimply stated transcription is the synthesis of RNA from a DNA template. It is initiated by binding of RNA polymerase to double-stranded DNA; this step involves a transition to … WebBacteria cannot remove intronic sequence from a gene, so if the gene for insulin were transcribed, it would translate to a nonfunctional protein. The bacterial RNA polymerase will not bind to the eukaryotic promoter sequence. ... Order the steps that pre-mRNA undergoes after eukaryotic transcription is initiated. 1. 5′ capping of transcript 2 ...
WebBacterial transcription typically involves three stages abortive initiation, elongation of mRNA and stalling of RNA polymerase by intrinsic RNA sequences or rho factor. Primarily, … WebNov 23, 2024 · Trans-encoded bacterial regulatory RNAs (sRNAs) are functional analogues of eukaryotic microRNAs (miRNAs). These RNA classes act by base-pairing complementarity with their RNA targets to modulate gene expression (transcription, half-life and/or translation). Based on base-pairing, algorithms predict binding and the impact of …
