Web16 mrt. 2024 · A single transcript can be read by multiple ribosomes at the same time forming a complex known as polysome (Munro et al. 1964). Once engaged, polysome will translate the mRNAs and would not readily exchange it for newly added mRNA until the translation of the initial mRNA is completed (Thompson and Gilbert 2024). Transcripts … WebIn translation, the codons of an mRNA are read in order (from the 5' end to the 3' end) by molecules called transfer RNAs, or tRNAs.
