Bacteria cells can be used to produce insulin for the treatment of diabetes in humans. Which best explains how the bacteria cells are able to produce insulin for humans?
The bacteria have been grown on a petri dish containing insulin.
The bacteria have been genetically engineered to contain the DNA needed to produce insulin.
The bacteria have been exposed to radioactivity to create mutant strains capable of producing insulin.
The bacteria have been grown on a petri dish containing sugar; the bacteria produce insulin in response to the sugar.
Which is most important when investigating ethical issues in biotechnology?
cost of the technology
advantage of the technology
public opinion of the technology
benefits of the technology outweighing the harm
Which would be reduced as a result of the development of pest-resistant crops?
use of organic fertilizers
use of chemical insecticides
practice of crop rotation techniques
practice of hydroponic farming techniques
Which of the following would result in a frameshift mutation?
Insertions only
Substitution only
Deletion only
Insertions and Deletions
A mutation is defined as:
A change in the cell's structure
Anything that changes in an embryo
Any change in the physical features of a human
A change in the DNA sequence
Why are insertion and deletion (frameshift) mutations so harmful?
They change all of the codons from the mutation on down the line, which changes the amino acid sequence
They insert things that an organism doesn't need.
They often delete things that organisms need.
Insertion and deletions are not any more harmful than substitution mutations.
