Biology Quiz

Which type of cells can differentiate into a variety of cells?

• stem cells

• nerve cells

• blood cells

• sperm cells

What was the Human Genome Project specifically trying to find?

• shape of DNA

• polymerase chains

• nucleotide base sequences

• forms of resistant DNA

Which has been a major application of the Human Genome Project?

• To produce alien life forms.

• To identify the structure of RNA.

• To determine the size of the human population.

• To trace ancestry of human populations.

For what reason is DNA fingerprinting most useful?

• gene therapy

• stem cell research

• investigating paternity

• developing recombinant DNA

What is the primary purpose of using restriction enzymes in gel electrophoresis?

• It restricts the number of base pairs that can be tested in a sample.

• It allows the strands of DNA to be cut into various lengths for testing.

• It makes the testing simpler by moving the strands into the gel faster.

• It allows the DNA strands to be charged so the electrical current can send the strands into the gel.

Which would be a benefit of a genetically engineered crop?

• lower sun tolerance

• increased pest resistance

• decreased fungal resistance

• increased water dependance

Which concerns may some people have about eating foods that have been genetically modified?

• creating obesity epidemic

• loss of biodiversity

• creating a super bacteria

• having an allergy to an inserted gene

Which would be best described as an advantage of stem cell research?

• Most adult stem cells are pre-specialized.

• It is completely unknown what the long-term effects of genetic interference could be.

• Most stem cells are derived from embryos that are not a patient’s own, and the patient’s body may reject them.

• It has the potential for discovering treatments and cures to several diseases including cancer, spinal cord injuries, diabetes, and many more.

Dogs are closely related to wolves. To prove this, what type of testing or experiment would a scientist most likely carry out?

• compare wolf and dog DNA

• examine their social habits and record similarities

• feed them similar foods and see if they have similar diets

• determine whether a female dog will care for a wolf pup

Maggie is a transgenic goat. How does being transgenic make Maggie different from non-transgenic goats?

• Maggie has DNA from both of her parents.

• Maggie has DNA that winds around proteins.

• Maggie has DNA implanted from another organism.

• Maggie has DNA that uses a different coding system.
