WebbA ribosome is a complicated but elegant “micro-machine” for producing proteins. Ribosomes are made up of ribosomal proteins and ribosomal RNA (rRNA). In prokaryotes, ribosomes consist of roughly 40 percent protein and 60 percent rRNA. A eukaryotic ribosome comprises three or four rRNA molecules and about 80 different proteins. WebbAn mRNA travels to the ribosome, which uses the information it contains to build a protein with a specific amino acid sequence. This process is called translation. Prokaryotes lack a nucleus, so their mRNAs are transcribed … WebbPost- transcriptional modification of mRNA in eukaryotes. In bacteria, transcription from DNA to mRNA is a direct pathway. However in eukaryotes once mRNA is synthesized by RNA Polymerase II, the mRNA goes through further modification (Fig. 11). The product following transcription is known as a primary transcript (or pre-mRNA). flow number agitator
