Question 1

selective breeding

Answer 1

uses controlled mating to develop an organism with the desired characteristics

Question 2

characteristics of selective breeding

Answer 2

-can take many generations
-may result in selection of undesirable traits along with desirable traits
-typically results in decrease of genetic diversity
=increases vulnerability to disease

Question 3

gene editing

Answer 3

-process by which DNA of an organism is modified by using technology
-examples:
Molecular cloning
CRISPR/Cas9
-Much faster and more targeted than selective breeding

Question 4

Gene editing technology is derived from nature

Answer 4

-Bacterial resistance to viruses
-DNA synthesis

Question 5

Bacterial resistance to viruses

Answer 5

-Restriction endonucleases
-CRISPR/Cas9

Question 6

DNA synthesis

Answer 6

-ligase
-DNA polymerase
