Question

33. Which of the following statements is NOT true of mRNA? a) Prokaryotic mRNAs are mainly polycistronic. b) Eukaryotio-mRNAs aremainly-menocistronio c) Prokaryotic mRNAs are capped with 7-methylguanosine Prokaryot ic mRNAs are immediately translated into protein without e) Euk aryotic mRNAs are extensively modified prior to translation genes are often organized in operons. Which of the following is NOT true about operons. DNA is transcribed into a single polycistronic mRNA 30 e) Polycistronic mRNA has individual ribosome binding sites. 4. What are the products of the reaction below? Mg2* Asp HO. OH OH H HO glycerol b) ATP-and-glycerot-3-phosphate Glycerol-3-phosphate and ADP d) Glycerol-AMP and pyrophosphate -e)-Phosphoryleted Aspartate andADP Answers circled may not be right can someone explain correct answers

Explanation / Answer

33) The correct answer is option C that is prokaryotic mRNA are capped with 7-methylguanosine because prokaryotes don't have 5' cap.

30) The correct answer is option C that is poly cystronic mRNA is spliced prior to translation. This statement is not true about operons because in order to splicing to occur, introns should be present in between genes but bacteria do not have introns, so splicing can't occur.

4) The correct answer is option C that is glycerol-3-phosphate and ADP.
