Example sentences for: ribosomes
How can you use “ribosomes” in a sentence? Here are some example sentences to help you improve your vocabulary:
This would imply that Tat up-regulates many ribosomal genes that may be necessary to produce functional ribosomes needed for viral mRNA translation.
Finally, upregulation of translation genes in Tat expressing cells is specially intriguing in light of the recent discovery of internal ribosome entry sites (IRESs) in HIV-1 gag ORF [ 43 ] . IRESs are thought to promote initiation of translation by directly binding to ribosomes, in a manner independent of the mRNA cap or of scanning through upstream sequences.
Concomitant with the increased eIF2α phosphorylation in the parental strain was a secondary shift of ribosomes from polysomes to free ribosomes.
Since, the TAR is located at the 5' end of all HIV-1 RNA transcripts and the presence of secondary structure at or near the 5' end of RNAs reduces the accessibility of the 5' cap to eIF4F, it is thought that this feature of HIV-1 mRNAs can inhibit their cap-dependent translation [ 44 45 46 ] . Therefore, a possible function of the HIV-1 gag IRES might be to serve as a mechanism to bypass the structural barriers to cap-dependent translation by recruiting ribosomes easily and directly to the gag ORFs.
The increased phosphorylation by IfkA normally occurs from 1 to 7 hours after the onset of development, resulting in a secondary shift from polysomes to free ribosomes for bulk mRNA.
