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. WebA ribosome is made up of two basic pieces: a large and a small subunit. During translation, the two subunits come together around a mRNA molecule, forming a complete ribosome. The ribosome moves forward …
