WebLike mRNA, +ssRNA (single-stranded RNA) viruses can immediately be translated by host cell ribosomes and do not need to bring an RNA-dependent RNA polymerase (RdRp) into the cell. RNA viruses with dsRNA (double stranded RNA), −ssRNA (negative-sense single-stranded RNA), or ambisense genomes must carry their own RdRp protein into the cell in … Web6 mei 2024 · Translation is the final step in the process of the cell carrying out genetic instructions. It starts, in a sense, with DNA making messenger RNA (mRNA) in a process called transcription. The mRNA is a sort of "mirror image" of the DNA from which it was copied, but it contains the same information. The mRNA then attaches itself to ribosomes.
