Proteins — practice question

Some antibiotics destroy prokaryotes by attaching to RNA polymerase. What impact will this have on protein synthesis?

  • ACodons on mRNA will be unable to hydrogen bond to complementary anticodons on tRNA.
  • BCondensation reactions joining RNA nucleotides will not take place to form mRNA.
  • CDNA will not unwind and unzip to allow for base pairing with RNA nucleotides.
  • DFree RNA nucleotides will not base pair to exposed bases on the DNA template strand.
