Exam 3- Chapters 12-15Return to Assessment ListPart 1 of 1 -83.33/ 100.0 PointsQuestion 1 of 402.5/ 2.5 PointsYour labmate’s ligation reaction didn’t work. The regular ATP had run out, so he fueled thereaction with dATP from the PCR kit. What advice can you give him?A. Suggest trying one of the other nucleotides from the PCR kit to drive the ligationreaction.B. Suggest adding all four nucleotides from the PCR kit.C. Add heat to the ligation reactions to provide energy, instead of ATP.D. Remind Sam that dATP is not the same as ATP.Feedback:For synthesizing DNA in PCR, nucleotides may be provided in separate tubes of dATP,dCTP, dGTP, and dTTP. Because these are deoxyribonucleotides, they do not have the samestructure as ATP, and therefore cannot be used as energy currency molecules to drive a ligationreaction.
Question 2 of 402.5/ 2.5 PointsDue to a random error by the aminoacyl tRNA synthetase, a tRNAVal was misloaded with Ile.What do you predict will result?
Feedback:Learning Objective: Analyze how genes determine the proteins found in all cellsQuestion 3 of 402.5/ 2.5 PointsWhat best describes the human karyotype?
