5. Translation.
6. Eukaryotic ribosomes are ten times larger than prokaryotic ones.
7. Not sure about this.But they are necessary for protein synthesis as they assemble amino acids into protein chains.
8. Ribosomal RNA is part of ribosome.These complex structures catalyze the assembly of amino acids into protein chains.They also bind tRNAs and various accessory molecules necessary for proteins.
9. When a ribosome is not working,it disassembles into two smaller units.

Answer:
No
Explanation:
The universality of the genetic code refers to how the codons for amino acids are always the same in almost all species. Amino acids have corresponding nitrogenous bases in pairs of three called a codon. so to have the same amino acids, all species would need the same nitrogenous bases.
