(GENETIC ENGINEERING) BIOLOGY QUESTIONS AND ANSWERS

(GENETIC ENGINEERING) BIOLOGY QUESTIONS
AND ANSWERS
genetic engineering - CORRECT ANSWER✅✅✅the process of manipulating genes



restriction enzymes - CORRECT ANSWER✅✅✅bacterial enzymes that recognize and bind
to specific short sequences of DNA and than cut the DNA between specific nucleotides


plasmid - CORRECT ANSWER✅✅✅DNA molecules that can replicate independently,
gene of interest is place inside after it is cut with restriction enzyme


What are plasmids used for? - CORRECT ANSWER✅✅✅sometimes genes inside provide
bacteria with genetic advantages, such as antibiotic resistance.


vector - CORRECT ANSWER✅✅✅an agent that is used to carry the gene of interest into
another cell


gene cloning - CORRECT ANSWER✅✅✅many copies of the gene of interest are made
each time the host cell reproduces


recombinant DNA - CORRECT ANSWER✅✅✅gene of interest + plasmid DNA



How is recombinant DNA made? - CORRECT ANSWER✅✅✅DNA fragments from the
organism containing the gene of interest are combined with the DNA fragments from the vector


sticky ends - CORRECT ANSWER✅✅✅produced protruding ends



genetic engineering steps - CORRECT ANSWER✅✅✅1. cutting DNA
2. making recombinant DNA
3. cloning (many copy's of the gene of interest are made)
