WebA chimeric tRNA with the human acceptor stem and other sequences from the yeast molecule acts similarly to the human tRNASer. The 3:70 base pair in the acceptor stem (C:G in yeast and A:U in humans) is a prime determinant of the specificity. Chimeric RNA, sometimes referred to as a fusion transcript, is composed of exons from two or more different genes that have the potential to encode novel proteins. These mRNAs are different from those produced by conventional splicing as they are produced by two or more gene loci. WebDec 8, 2009 · ( a) Schematic figure of chimeric tRNA concept: chimeric tRNAs are engineered by substituting the wild-type anticodon in tRNA Ser to specific triplets coding for other amino acids.
