Pol III is a type of enzyme that synthesizes transfer RNA (tRNA). You would expect this enzyme to form: correct answers phosphodiester bonds between adjacent ribose molecules You would expect DNA in mitochondria to be correct answers circular between the time when pre mRNA is generated and when introns are removed from it, a type of RNA called SnoRNA adds a methyl group to some bases in the pre mRNA. From what you know about RNA processing, you would expect these enzymes to function in the...
