It also is preparation for a review of all of the practice questions from unit 3, which is due Mon ay want to work on these quizzes together, or use this quiz to guide your studying and the old question revie onday to assess your studying. D l Question 1 0.2 pts (LO 15.7) How do the amino acids get added to a new polypeptide in the right order? The promoter moves along the mRNA adding the correct amino acid by reading the codons O The anticodons on tRNA molecules pair with the codons on the mRNA to bring the next amino acid to the polymer o The amino acids bind to the codons on the mRNA, then the protein polymerase makes the phosphodliester bonds The ribosome reads the codons and moves the new polypeptide to the right site for each amino acid for esample to the P site for odding phenylalarine Question 2 0.2 pts LO 15.5) After an mRNA is madc and is still in the nucleus of a e quick-charging function s 3 6

Answer 1

1. c) the amino acids to the codons the mRNA the protein polymerase make the phosphodiester bond
2. d) the 5' end of the mRNA modified to make mRNA more stable
3. a) are processed to the golgi apparatus,then moved to the RER for further processing into vesiscles for exocytosis
4. b) make ATP and NAPDH from the light energy that is reflected by the photopigments
5. d) is parallel whereas the leading strand is antiparallel
6. d) enchancers binding directly to promoter proteins so RNA polymerase can bind to histones
7. a) half of the double helices to the heavy and half to be light

9)c) many prokaryotic use non oxygen electron acceptors for anaerobic respiration

10)c) telmers are absent
