Dr Rob Carter - Genetic Engineering

What is the main topic Dr. Rob is discussing in his presentation?

• The history of coral reefs

• Genetic engineering and its implications

• The process of photosynthesis

• The migration of fish species

Which organism did Dr. Rob mention as being genetically modified in his example?

• A jellyfish

• A coral

• A fish

• A plant

Why did Dr. Rob investigate the different pigments found in corals?

• To learn how corals move

• To understand the reasons behind coral colors and their roles

• To measure the size of coral reefs

• To find out what corals eat

If you wanted to create a fluorescent colony of bacteria, what would be the correct procedure based on the text?

• Add blue dye to the bacteria and expose them to sunlight.

• Take all the RNA out of an organism, throw it into E. coli, and select the colonies that glow.

• Feed the bacteria with coral proteins.

• Mix jellyfish and coral extracts together.

What is the function of exons in a gene?

• They are coding regions that must be joined together before protein can be made

• They are non-coding regions that are removed from RNA

• They help bacteria process introns

• They produce fluorescent proteins

Which of the following best describes a palindrome in the context of DNA sequences?

• A sequence that reads the same forwards and backwards.

• A sequence that forms a loop.

• A sequence that codes for a protein.

• A sequence that is only found in bacteria.

What is a plasmid?

• A type of bacterial enzyme.

• A circular piece of DNA found in many bacterial species.

• A protein that cuts DNA.

• A sequence of RNA used in translation.

Why is it important that restriction enzymes cut DNA at specific sites rather than randomly?

• It allows for the creation of sticky ends that can be joined with other DNA.

• It increases the speed of DNA replication.

• It prevents the DNA from being degraded.

• It ensures that only bacterial DNA is cut.

If a plasmid carries an antibiotic resistance gene, what happens to bacteria carrying that plasmid when grown on antibiotic-containing media?

• The bacteria will die.

• The bacteria will survive.

• The bacteria will mutate.

• The bacteria will stop replicating.

How did the scientist confirm the presence of the red fluorescent protein colony?

• By checking the plates again after more time had passed

• By using a microscope immediately

• By tasting the colony

• By adding more antibiotics
