Question 15 of 40Why did Mendel’s work go unnoticed?A. The scientific community believed new traits develop through mutationB. The scientific community believed new traits developed through blending of traits from parents.C. The scientific community believed dominant traits would always mask recessive traitsD. The scientific community believed that physical characteristics were dependent on many genes interacting.E. The scientific community believed that traits are inherited in distinct groups.
Feedback:Learning Objective: Describe the scientific reasons for the success of Mendel’s experimental workQuestion 16 of 40An experiment started with15N15N DNA. After two generations in14N medium, E. coli will haveNN14NN
Feedback:CorrectQuestion 17 of 40Why do so many geneticists focus on studying yeast, fruit flies, nematodes, mice or the small plantArabidopsis?
2.5/ 2.5 PointsC.They have multiple features that allow for cheap, fast and efficient manipulation of genes and chromosomes.D. They are some of the few organisms in which mutations can be generated.Feedback:Genetic model organisms have a quick lifecycle, small size, and resilience that makes them easy toculture in the lab.Question 18 of 40The codon AUG specifies the amino acid methionine. What would the tRNA anitcodon be thatrecognizes this codon?
2.5/ 2.5 PointsFeedback:CorrectQuestion 19 of 40Your labmate’s ligation reaction didn’t work. The regular ATP had run out, so he fueled the reactionwith 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 ligation reaction.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 same structure as ATP, and thereforecannot be used as energy currency molecules to drive a ligation reaction.
