Genetic engineering B6

Question 1

Is selective breeding an effective, quick method?

Answer 1

No, this is because it takes a long amount of time for organisms to reach sexual maturity, gestate organisms and process the next generation. As well as this, due to sexual reproduction, there is variation. Characteristics are not guaranteed.

Question 2

What is genetic engineering?

Answer 2

taking a gene that codes for a desired characteristic from an organism, then putting the gene in the genome of another organism.

Question 3

examples of GM

Answer 3

Corn that can produce a toxin that kills off damaging insects.

Question 4

what are vectors?

Answer 4

usually a bacterial plasmid, single loop of DNA, or a virus.

Question 5

What is the function of a vector?

Answer 5

Plasmids are cut by a restrictive enzyme leaving it with corresponding bases that act as sticky ends that connect with the isolated gene, using ligase enzyme. the plasmid/ vector inserts the gene into the requires cell.
