How does an RNA polymerase know to start at the start codon and stop at the stop codon? Where is that information (where to stop and start) stored? Why does it start at AUG? What is the significance of the start and stop of codons in protein synthesis? ...

Codons transfer the genetic information from the nucleus to the ribosomes where protein synthesis takes place. What is called codon? A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis. ... Each codon ...

Termination is initiated by stop codons (UAA, UAG, or UGA) that do not have corresponding tRNAs, but instead signal release factors to put an end to protein synthesis. The polypeptide is sent off, and the two ribosomal subunits separate. ...
What is the function of an RNA prime during protein synthesis? View Solution Formation of a specific protein is necessary for a cell. What will happen if the mRNA coding for this protein synthesis does not have codons UAA, UGA and UAG ?
Cell-associated (CA) HIV RNA has received much attention in recent years as a surrogate measure of the efficiency of HIV latency reversion and because it may provide an estimate of the viral reservoir size. This review provides an update on some recent i
For example, the codons AUU, AUC, and AUA all correspond to the amino acid isoleucine. Mutations Mutations are changes that occur in the nucleotide sequence of DNA. “They can occur spontaneously when DNA is being replicated during cell division, but also can be induced by environmental factors...
mRNA degradation, which has traditionally been thought to result from stop codons that terminate translation more 5′ than is usual on an mRNA. Short ORFs (sORFs). Open reading frames of fewer than 100 codons on mRNAs that are not known to encode a canonical (long) protein. sORFs are a ...
