This review covers key concepts in DNA technology, biotechnology, and genetic engineering, highlighting methods such as cloning and the manipulation of living organisms for practical purposes. It discusses the modification of genetic material, techniques for introducing foreign genes into bacteria, and the use of selective breeding and hybridization to enhance desired traits. Additionally, it examines genetically modified organisms (GMOs) and the role of restriction enzymes in DNA manipulation, providing insights into the latest advancements in biotechnology.

What are some examples of genetically modified organisms (GMO’s)?
Golden Rice that produces a Vitamin A precursor in the hopes of alleviating Vitamin A deficiency in developing countries. • Bt Corn that has a gene inserted into its genome, which causes the corn to produce a toxin against poisonous caterpillars. • Human Insulin derived from the pancreas of cows and pigs. The insulin gene has been inserted into strains of bacteria and yeast that now produce insulin.
A plasmid is a small, circular piece of DNA found in bacteria
A) are found only in bacterial cells • B) can join with each other • C) can join only with complementary fragments of the same species • D) are immediately digested by enzymes in the cytoplasm of the cell Fragments of DNA having complementary “sticky ends”:

This is the uptake and expression of foreign DNA via plasmids:
Transformation This is the uptake and expression of foreign DNA via plasmids:
This is the uptake, genomic incorporation and expression of foreign DNA via viruses:
Transduction This is the uptake, genomic incorporation and expression of foreign DNA via viruses:
Plasmids can replicate themselves inside of bacterial cells • Plasmids also usually contain genes for antibiotic resistance.
How would you put your gene of interest into a bacterial plasmid?
Isolate the plasmid from the bacteria. • Isolate your gene of interest from a eukaryotic cell. • Cut your plasmid with a restriction enzyme. • Cut your gene of interest with the same restriction enzyme (sticky ends) • Mix your plasmid and gene together. • DNA ligase will join the two DNA pieces. • The bacteria will replicate the plasmid and your gene of interest.
A) determinant DNA • B) recombinant DNA • C) plasmid DNA • D) restriction DNA A strand of DNA formed by the splicing of DNA from 2 different species is called:

This is a process by where DNA is copied and amplified very quickly:
A) are used in genetic engineering to make copies of RNA • B) require the same ingredients to make copies of DNA • C) are used in genetic engineering to make proteins • D) None of the above PCR and DNA replication:

How do bacteria use restriction enzymes as a defense mechanism?
Bacteria do not have immune systems, so they use restriction enzymes to protect themselves from bacteriophages. • The restriction enzyme will prevent the bacteriophage DNA from being harmful once inside the bacteria. How do bacteria use restriction enzymes as a defense mechanism?
A) inducing a mutation on a source chromosome • B) cutting the DNA with a restriction enzyme • C) recombining pieces of DNA from different organisms • D) cloning and screening bacterial cells. Which of the following procedures is NOT a usual step in an rDNA experiment?
