Question 1 1. Which of the following statements could NOT be used to describe a multifactorial trait?

Question 2 2. Which of the following statements is TRUE?

Question 3 3. Which of the following is the main purpose of the origin of replication?

Question 4 4. A scientist isolates a human DNA repair gene and inserts it into a plasmid. The plasmid is inserted into a bacterial cell, so more plasmid can be produced.

Which of the following statements regarding VECTORS is TRUE?

Question 5 5.

Which of the following experiments uses a selectable marker?

I. An experiment in which genetically modified bacteria are blue and all other bacteria are white.

II. An experiment in which the bacteria that has been genetically modified to produce the human insulin protein is identified by checking the DNA sequence.

III. A fruit fly experiment in which a lethal gene kills all progeny except those of the desired genetic makeup.

Question 26 26.

Evaluate each of the following sets of data separately. Which of them provide evidence that the trait is polygenic?

I. The genotype at loci A, B and C each produces a protein that influences the length of an organism by an average of 0.6, 0.4 and 0.3 cm, respectively.

II. Three different alleles of gene D affect the length of an organism by an average of 0.6, 0.4 and 0.3 cm, respectively.

III. Loci E, F and G each modulates an independent pathway, which plays a role in determining the length of an organism.
