Web1 de jan. de 2016 · tRNA (transfer RNA) tRNA. (transfer RNA) The shortest RNA molecule in the cell (ca. 3.8S), consisting of about 76 to 86 nucleotides. tRNAs carry amino acids to the ribosomes during protein synthesis. The majority of cells have 40 to 60 types of tRNAs because most of the 61 sense codons have their own tRNA in the eukaryotic cytosol. Web15 de fev. de 2024 · tRNAs are transcribed from the genes present in DNA. And as we know, DNA runs from a 5′ end to a 3′ end, so tRNA that is synthesized does have the same direction.
