Question 20 of 402.5/ 2.5 PointsNondisjunction during meiosis II will result in ________.A. nB. n-1C. n+1
D. n+1 and n-1E. n,n-1 and n+1Feedback:CorrectQuestion 21 of 402.5/ 2.5 PointsWhat causes RNA polymerase to stall so that the rho protein bumps into it and knocks it off theDNA?
Feedback:Learning Objective: Describe how and when transcription is terminatedQuestion 22 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 23 of 402.5/ 2.5 Points________ unwinds the helix during replication.
B. DNA helicaseC. DNA primaseD. DNA ligaseE. DNA polymerase IFeedback:CorrectQuestion 24 of 402.5/ 2.5 PointsSerious disease syndromes are associated with trisomy of chromosome 21 (Down syndrome), 18(Edwards syndrome) and 13 (Patau syndrome).What is the result of trisomy of the other chromosomes?A. no disease symptomsB. minor disease symptomsC. disease symptoms with varying severity based on genetic background
D. lethal early in developmentFeedback:Correct- Trisomies of the other chromosomes are less-often mentioned because theyare more devastating, not less. Fetuses with other trisomies seldom complete development andare typically lost as miscarriages, sometimes quite early. Even for trisomy 13, 18 or 21, asignificant number are lost as miscarriages.Question 25 of 402.5/ 2.5 PointsMature tRNA has an amino acid binding site at one end and the other end interacts with themRNA by complementary base pairing due to the ________.
Feedback:Learning Objective: Explain how tRNAs and rRNAs are processed
