What is co transcriptional translation?
Coupled transcription-translation (CTT) is a hallmark of prokaryotic gene expression. CTT occurs when ribosomes associate with and initiate translation of mRNAs whose transcription has not yet concluded, therefore forming “RNAP. mRNA. ribosome” complexes.
What is DNA replication transcription and translation?
DNA Replication creates two new strands of DNA from one strand of DNA. Transcription makes RNA from a DNA template. Translation links together amino acids to make protein from a RNA template.
What is transcriptional polarity?
Transcriptional polarity results in decreased synthesis of inefficiently translated mRNAs and therefore in decreased expression of downstream genes in the same operon (intercistronic polarity).
Is polyadenylation a transcriptional?
In addition to capping, splicing and cleavage/polyadenylation, some transcripts are processed co-transcriptionally by A–I editing or miRNA excision from introns.
Where is RNA translated?
Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins. The ribosome has a small and a large subunit and is a complex molecule composed of several ribosomal RNA molecules and a number of proteins.
What are RNA codes?
RNA is composed of four nucleotides: adenine (A), guanine (G), cytosine (C), and uracil (U). Three adjacent nucleotides constitute a unit known as the codon, which codes for an amino acid.
What is RNA translation?
Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA).
What is the difference between replication transcription and translation?
Differences. DNA replication occurs in preparation for cell division, while transcription happens in preparation for protein translation.
