Transfer Rna (tRNA) Notes
Transfer Rna (tRNA) The RNA which possesses the capacity to combine specifically with only one amino acid in a reaction mediated by a set of amino acid-specific enzymes called aminoacyl-tRNA synthetases; transfers that amino acid from the amino acid pool to the site of protein synthesis and recognizes the codons of the mRNA is known as the soluble RNA (sRNA) or transfer RNA … [Read more...] about Transfer Rna (tRNA) Notes
Messenger RNA Questions And Answers
Messenger RNA Questions And Answers Question 1. What are intervening sequences or introns? What is mRNA splicing? Answer: Untranslated sequences that interrupt the coding sequence of a transcript and that are removed before translation begins. Removal of introns. Question 2. Many eukaryotic genes contain noncoding introns that separate the coding … [Read more...] about Messenger RNA Questions And Answers
RNA Editing Notes
RNA Editing In the late 1980s, still, another quite unexpected form of post-transcriptional RNA processing was discovered in several organisms. In this form, referred to as RNA editing, the nucleotide sequence of a pre-mRNA is changed before translation. As a result, the ribonucleotide sequence of the mature RNA differs from the sequence encoded in the exons of the DNA … [Read more...] about RNA Editing Notes
Rna Processing And Modifications Notes
Modification And Processing Of mRNA Most eukaryotic mRNAs undergo a quite complicated series of modifications and processing events before translation occurs. These include: Chemical modification to the two ends of the mRNA molecule (Capping). Polyadenylation Removal of introns (Splicing). In a few special cases, alterations to the nucleotide sequence of the mRNA … [Read more...] about Rna Processing And Modifications Notes
