- maternal mRNA clearance
The chemical reactions and pathways resulting in the clearance of maternal mRNA transcripts from the zygote as part of the maternal-to-zygote transition in gene expression.
- CUT catabolic process
The chemical reactions and pathways resulting in the breakdown of cryptic unstable transcripts (CUTs).
- reverse transcription
A DNA synthesis process that uses RNA as the initial template for synthesis of DNA, but which also includes an RNase activity to remove the RNA strand of an RNA-DNA heteroduplex produced by the RNA-dependent synthesis step and use of the initial DNA strand as a template for DNA synthesis.
- transcriptional attenuation
A negative regulation of gene expression mechanism by which bacteria and archae can direct RNA polymerase to prematurely terminate transcription in response to a specific metabolic signal.
- plastid transcription
The synthesis of RNA from a plastid DNA template, usually by a specific plastid RNA polymerase.
- transcription antitermination
A positive regulation of gene expression mechanism that allows RNA polymerase to continue transcription beyond a termination site, thus allowing expression of downstream genes under specific conditions.
- rRNA transcription
The synthesis of ribosomal RNA (rRNA), any RNA that forms part of the ribosomal structure, from a DNA template.
