WebTransfer RNA (abbreviated tRNA and formerly referred to as sRNA, for soluble RNA) is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length (in eukaryotes), that serves as the physical link between the mRNA and the amino acid sequence of proteins. tRNAs genes from Bacteria are typically shorter (mean = 77.6 bp) than tRNAs … WebIn RNA, the pentose sugar is ribose, which has a hydroxyl group attached to the 2′ carbon. In DNA, the pentose sugar is deoxyribose, which has a hydrogen atoms attached to the 2′ carbon. The “deoxy” in the name of DNA refers to the missing oxygen atom at the 2′ carbon (Figure 5.2). Nucleic acids are long, linear chains of nucleotides.
