Were there any unusual
findings in your creating of transgenic organisms? Explain.
Use your textbook to
answer the remaining questions. Identify ways GM crops can have an improved
yield or improved nutritional value.
One drawback to GM crops
is the question of whether they are truly safe in the long run or not. Are you
in favor of banning GM crops—even if it means food prices would rise? Do you
approve of ecoterrorists who burn GM crops and destroy biotechnology labs?
One step further into GM
organisms is gene pharming, research, and xenotransplantation. Distinguish
between these three uses of GM animals.
The manipulation of an
organism’s genes can be extended to humans in a process called gene
therapy. What exactly is gene therapy? What are the two types. Provide
examples of each type of gene therapy.
proteomics and the proteome.
Why does a cell contain
many more proteins than there are protein-coding genes?
Much genetic evidence
indicates that humans and chimpanzees are very closely related, despite the
observation that chimpanzees have 48 chromosomes and we have only 46. At first,
the difference in chromosome number was considered significant—so significant
that the great apes (chimpanzees, gorillas, and orangutans) and humans were
classified into different families. The apes were in family Pongidae, and
humans were in family Hominidae. Further research has proven that we are closer
to the chimps than we thought. Explain.

Several hours; 16 B. one hours, 5 C. zero hours, 10 D. several hours, 1
In whose womb is the
Mimi B. momi C. megdo
What is the gestation
period (pregnancy length) for a mouse?
20 days B. 18 days C. 19 days D. 21 days
Using your textbook,
answer the remaining questions in the lab report. Based on your textbook, what
type of cloning did you do with the mice today?
Reproductive B. sensitive C. human
Gene cloning is a bit of
a different process. Describe it briefly in a paragraph. Be sure to use the key
words: rDNA, vector, plasmid, restriction enzyme, DNA ligase.
What are the
uses/services of GM bacteria?
Identify which type of
noncoding DNA occupies the largest percentage of the genome and functions it
