No, the transfer RNA (tRNA) does not read the codons on the messenger RNA (mRNA) strand, the codons are read by the ribosome and matched by it to the...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer y...
These conditions are obvi-ously not identical in cases when the translation proceeds with more or less uniform speed along the polypeptide chain, and when the ribosome stalls at certain codons, thus leaving time for the already fi nished part of the chain to fold into a stable structure and ...
Restriction–modification (R-M) systems are highly widespread among bacteria and archaea, and they appear to play a pivotal role in modulating horizontal gene transfer, as well as in protecting the host organism against viruses and other invasive DNA par
TSEs are typically fatal neurodegenerative diseases; 90% of CJD patients die within 1 year of diagnosis which occurs sporadically at an annual incidence of 1 per million populations [1, 2]. Among all CJD cases, 10–15% has been reported as autosomal dominant disorders, with mutations in the...
(8-fold, Table2) using the same phage assay with a comparable number of restriction sites on phage genome. This may be explained by the fact the EcoRI R-M system has cluster of two codons (arginine and leucine), that are delivered by two different tRNAs, and this affects translation of...
Immunoblot analysis with the m6A antibody (top) shows that levels of m6A in poly(A) RNA (left) and poly(A) tail-depleted RNA (right) are comparable. Removal of poly(A) tails was confirmed using 3′RACE and RT-PCR to detect β-actin; no product is detected in the tail-depleted ...
