acceptor RNA,soluble RNA,tRNA ribonucleic acid,RNA- (biochemistry) a long linear polymer of nucleotides found in the nucleus but mainly in the cytoplasm of a cell where it is associated with microsomes; it transmits genetic information from DNA to the cytoplasm and controls certain chemical proces...
The triplet codes in DNA needed to specify a specific polypeptide chain are found in the: a) cytoplasm. b) gene. c) codon of mRNA. d) anticodon of tRNA. If the base sequence on a strand of DNA is TACCCGTATACT, what would be the sequence of the codons ...
As a consequence of these changes in the genetic material, the protein synthesizing capacity of the cell is affected. For example, it was observed that if the synthesis of TMV occurs in the presence of 5-fluorouracil, more than half of the uracil normally present in the TMV-RNA may be ...
It is suggested that while the standard base pairs may be used rather strictly in the first two positions of the triplet, there may be some wobble in the pairing of the third base. This hypothesis is explored systematically, and it is shown that such a wobble could explain the general natu...
That question was a midterml essay topic on Gene expression course that I have taken last semester. Here is what I found … Why Triplet Codon ? “The origin of the code is perhaps the most perplexing problem in evolutionary biology. The existing translation machinery is at the same time so...
2b). Thus, triplet pairing of SufB2 to the first three Cs of the CCC-C motif is necessary and sufficient for rapid delivery of the tRNA to the A site and its participation in peptide-bond formation. The A-site activity of SufB2 depends on the sequence of the anticodon loop...
Synonymous mutations change the triplet of nucleotides among degenerate mRNA codons encoding the same amino acid, leading to an altered mRNA sequence that encodes the same protein primary structure. Such mutations can alter the translation-elongation rate of ribosomes and have been found to alter the...

Accurate chromosomal DNA replication is essential to maintain genomic stability. Genetic evidence suggests that certain repetitive sequences impair replication, yet the underlying mechanism is poorly defined. Replication could be directly inhibited by th
The GAA-triplet repeat leads to transcriptional silencing of FXN that is caused most likely by heterochromatin condensation of the locus [176], which drastically reduces transcription of FXN by 70%–95% [177], [178]. A recent investigation reports on the transcriptional silencing of FXN, ...
