M11L1 Uses fpr Geneticis

By inserting DNA from one organism into another, humans have been able to improve the food supply and make crops more resistant to insect damage.  Which type of technology is this an example of?

• recombinant DNA

• DNA fingerprinting

• gel electrophoresis

• karyotype

Which is an example of recombinant DNA technology?

• identifying the remains of an unknown person by using gel electrophoresis

• developing a DNA fingerprint from blood left at a crime scene to identify a suspect

• inserting a gene from a cold water fish into a strawberry so it becomes frost-resistant

• breeding the best of the best to produce the best desireable trait for that organims

How does the DNA from two different organisms combine?

A bonds with G and T bonds with C

• A bonds with T and G bonds with C (Because it is DNA)

• A bonds with C and G bonds with T (DNA backwards)

• A bonds with C and G bonds with T (Curvy letters to Stick letters)

• A bonds with U (because it is RNA)

Which is the first step in creating recombinant DNA?

• The DNA of an animal cell is cut with enzymes to remove a certain gene

• Recombinant DNA with both animal and bacterial DNA is placed in the bacterial cell.

• Bacteria reproduce quickly and begin making the animal protein coded for in the animal DNA.

• The DNA is used to create GMO's that are used to help humans with everyday life.

Which molecule is used to cut genes from human DNA and bacteria plasmids so they can be spliced together?

• Recombinant DNA

• Plasmid

• Restriction enzyme

• Glue
