a. Zombies
b. The cost of genetic engineering will
rise
c. Humans will start to splice their genes to be
able to photosynthesize
d. Accidently trigger unwanted changes
(unpredictable consequences)
e. All of the above
17. What takes place during the termination stage of translation to
end the protein-making process?
a. Nonsense codons are recognized as release factors
b. Continuously moves the off-loading tRNA between the A and P
sites
c. Initiation factors (proteins) position the tRNA on the ribosomal
surface (rRNA) at the P site where the peptide bond
forms
d. When a tRNA attaches a ribosome, its amino acid is attached
adjacent to the initial methionine
e. Relocated the initial tRNA to the E site and ejects it from the
ribosome (rRNA)
18. What is the definition of gene flow?
a. Genetic mutations occurring at a very slow
rate
b. When some individuals leave behind more
progeny than others and the rate at which they do so is affected by
phenotype or behavior causing a change in alleles frequencies over
time
c. The movement of alleles from one population to
another
d. When frequencies of particular alleles may
change drastically due to chance alone
e. None of the above
19. According to the video Genetic Engineering Will Change

scientists experimented with DNA during the (a) 1960s, (b) 1970s,
(c) 1980s, or (d) 1990s?
a. Scientists in the 1960s were the first to
inject DNA in bacteria, plants, and animals to modify them for
agriculture and medical purposes
b. Scientists in the 1970s were the first to
obtain GMO patents which were given out for certain microbes that
could absorb oil
c. Scientists in the 1980s were the first to put
radiation on plants to see if they could cause random
mutations

create the edible GMO called the flavor savor tomato

20. What is the function of elongation factors?
a. Proteins that position the tRNA on the
ribosomal surface at the P site where the peptide bond
forms
b. Specific tRNA molecules that attach specific
amino acids through the action of these enzymes
c. Release the newly made polypeptide from the
ribosomes
d. Is specialized to transcribe rRNA and
recognize promoters that are unique to specific enzymes
e. Assists in binding tRNA carrying an amino acid
to the exposed mRNA codon at the A site
