The process of transcription is a major source of DNA damage, due to the formation of single-strand DNA intermediates that are vulnerable to damage. [53] The regulation of transcription by processes using base excision repair and/or topoisomerases to cut and remodel the genome also increases the vulnerability of DNA to damage. [53]
Transcription is the process by which the information contained in a section of DNA is replicated in the form of a newly assembled piece of messenger RNA (mRNA). Enzymes facilitating the process include RNA polymerase and transcription factors. In eukaryotic cells the primary transcript is pre-mRNA. Pre-mRNA must be processed for translation to ...
The transcription-translation process description, mentioning only the most basic "elementary" processes, consists of: production of mRNA molecules (including splicing), initiation of these molecules with help of initiation factors (e.g., the initiation can include the circularization step though it is not universally required),
Transcription initiation sites generally occur on both strands of an organism's DNA, and specify the location, direction, and circumstances under which transcription will occur. If the transcript encodes one or (rarely) more proteins , translation of each protein by the ribosome will proceed in a 5′-to-3′ direction, and will extend the ...
When transcription is arrested by the presence of a lesion in the transcribed strand of a gene, DNA repair proteins are recruited to the stalled RNA polymerase to initiate a process called transcription-coupled repair. [47] Central to this process is the general transcription factor TFIIH that has ATPase activity.
The process of gene expression itself is a source of endogenous DNA damages resulting from the susceptibility of single-stranded DNA to damage. [8] Other sources of DNA damage are conflicts of the primary transcription machinery with the DNA replication machinery, and the activity of certain enzymes such as topoisomerases and base excision ...
Translation promotes transcription elongation and regulates transcription termination. Functional coupling between transcription and translation is caused by direct physical interactions between the ribosome and RNA polymerase ("expressome complex"), ribosome-dependent changes to nascent mRNA secondary structure which affect RNA polymerase activity (e.g. "attenuation"), and ribosome-dependent ...
Bacterial transcription is the process in which a segment of bacterial DNA is copied into a newly synthesized strand of messenger RNA (mRNA) with use of the enzyme RNA polymerase. The process occurs in three main steps: initiation, elongation, and termination; and the result is a strand of mRNA that is complementary to a single strand of DNA.
