Question 4.4. (TCO 8) If a person has a mutation in a proto-oncogene, what will happen? (Points : 2)

       The mutation will not result in cancer unless (or until) there are additional mutations in genes, such as tumor suppressors.
       The mutation will deactivate the proto-oncogene.
       The mutation will inevitably cause cancer.
       The mutation will have a greater impact on increasing cancer risk only if the person is elderly.
       The mutation will inhibit cell division.

Question 5.5. (TCO 8) Some cancers can be inherited. Which of the following statements about inherited cancers is true? (Points : 2)

       These cancers are inherited as a dominant trait.
       Mutations that occur in somatic cells can be passed from parent to offspring.
       Not every individual with the mutation will get cancer.
       Lifestyle will have little impact on cancer risk for these individuals.
       Most cancers are inherited.

Question 6.6. (TCO 8) Operons contain regulatory genes that code for _____. (Points : 2)

       RNA polymerase
       repressors
       promoters
       enzymes
       lactose

Question 7.7. (TCO 8) What do transcription factors bind to? (Points : 2)

       DNA
       Signal molecules
       Plasma membrane receptors
       Proteins
       mRNA

Question 8.8. (TCO 9) A microbiologist wants to make bacteria produce a foreign protein. He has cloned the protein gene into a plasmid. What is the next step? (Points : 2)

       The plasmid is inserted into the main bacterial chromosome.
       The plasmid multiplies and produces the protein outside of the bacterium.
       The bacterial chromosome should be genetically engineered. The plasmid is just used to help the bacterium replicate.
       The plasmid is taken up by the bacterium, the plasmid replicates, and the protein is produced inside the bacterium.
       The bacterial genome and the plasmid are inserted into the genome of the species that contains the desired gene.

Question 9.9. (TCO 9) Which of the following is an example of a transgenic organism? (Points : 2)

       An organism carrying a gene that was acquired by artificial means
       The first organism in which a particular mutation has appeared
       An organism carrying genes from two different parents
       A cloned organism carrying two different alleles
       An organism that gestated in an artificial womb

Question 10.10. (TCO 9) If a human’s _____ cells are genetically modified, this may have an effect on the person’s offspring. (Points : 2)

       intestinal
       immune
       pancreatic
       gametic
       somatic

1. (TCO 8) Bacterial RNA polymerase binds to the _____. (Points : 2)

       operator
       proto-oncogene
       regulatory gene
       promoter
       exon

Answer:

1). Promoter

Both RNA polymerase and transcription factors bind with the promoter.

2). Initiation, codon recognition, peptide bond formation, translocation, termination

i. initiation. ii. elongation (codon recognition, peptide bond.formation and translocation). iii. termination.

3). Initiation, elongation, termination

4). The mutation will not result in cancer unless (or until) there are additional mutations in genes, such as tumor suppressors.

5).

Most cancers are inherited.
