Capitolo 11
Attenuazione della trascrizione nei procarioti
Transcriptional attenuation occurs when RNA transcription is prematurely terminated due to the formation of a terminator mRNA hairpin…
Riboswitch (interruttore genico a RNA)
Riboswitches are non-coding mRNA domains that regulate the transcription and translation of downstream genes without the help of proteins.…
RNA modificato
RNA editing is a post-transcriptional modification where a precursor mRNA (pre-mRNA) nucleotide sequence is changed by base insertion, deletion, or…
Trasporto regolamentato di mRNA
In eukaryotes, transcription and translation are compartmentalized; an mRNA is first synthesized in the nucleus and then selectively transported to…
Scansione che perde - Leaky scanning
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start…
Stabilità dell'mRNA ed espressione genica
The structure and stability of mRNA molecules regulates gene expression, as mRNAs are a key step in the pathway from gene to protein. In eukaryotes,…
Interferenza dell'RNA
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the expression of a gene by binding to its messenger RNA (mRNA)…
MicroRNA
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of…
siRNA - Piccoli RNA interferenti
Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional…
piRNA - RNA interagenti con Piwi
PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs…
CRISPR e crRNA
Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to…
lncRNA - RNA lunghi non codificanti
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces…
Ribozimi
The term ribozyme is used for RNA that can act as an enzyme. Ribozymes are mainly found in selected viruses, bacteria, plant organelles, and lower…
Condizioni sulla Terra primordiale
Around 4 billion years ago, oceans began to condense on earth while volcanic eruptions released nitrogen, carbon dioxide, methane, ammonia, and…
La fusione assoluta e relativa PCR quantitativa dei dati per quantificare STAT3 Splice Variant Trascrizioni
Human signal transducer and activator of transcription 3 (STAT3) is one of many genes containing a tandem splicing site. Alternative donor splice…
Sistema di espressione plasmide controllato da Transcriopzionalmente per l'analisi della stabilità delle trascrizioni dell'mRNA nelle cellule epiteliali primarie
Studying posttranscriptional regulation is fundamental to understanding the modulation of a given messenger RNA (mRNA) and its impact on cell…
Interferenza dell'RNA nei Coleotteri acquatici come potente strumento per manipolare l'espressione genica in punti specifici del tempo di sviluppo
RNA interference (RNAi) remains a powerful technique that allows for the targeted reduction of gene expression through mRNA degradation. This…
