WebApr 12, 2024 · One of the stranger phenomena that can occur during gene translation is where, as a ribosome reads along the mRNA, various cellular and molecular properties contribute to stalling the ribosome on a slippery sequence, shifting the ribosome into one of the other two alternate reading frames. The alternate frame has different codons, so … WebFeb 13, 2024 · Transcriptional regulation usually requires the action of several proteins that either repress or activate a promotor of an open reading frame. These proteins can counteract each other, thus allowing tight regulation of the transcription of the corresponding genes, where tight repression is often linked to DNA looping or cross-linking.

WebWell the open reading frame would be the sequence that contains no stop codon and is read by the polymerase and subsequently by the ribosome to form the protein. A reading frame in itself is just a sequence of nucleotides, cut into codons. All sequences will have 3 different reading frames. http://bioweb.uwlax.edu/GenWeb/Molecular/seq_anal/translation/translation.html dhs child welfare oklahoma
