WebAug 19, 2024 · The RNA Polymerase molecule is made up of 2 domains and 5 subunits: Core and holoenzyme; Subunits (β, β’, α (αI and αII), ω,) The promoter is the sequence of DNA that is required for accurate and specific initiation of transcription, and also, it is the sequence of DNA to which RNA polymerase binds accurately to initiate transcription. WebAntitermination is the prokaryotic cell's aid to fix premature termination of RNA synthesis during the transcription of RNA.It occurs when the RNA polymerase ignores the termination signal and continues elongating its transcript until a second signal is reached. Antitermination provides a mechanism whereby one or more genes at the end of an …

WebAfter entry into the target cell, the human immunodeficiency virus type I (HIV) integrates into the host genome and becomes a proviral eukaryotic transcriptional unit. Transcriptional regulation of provirus gene expression is critical for HIV replication. Basal transcription from the integrated HIV promoter is very low in the absence of the HIV transactivator of …
WebTranscription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination.
