Which enzyme is used to cut DNA at specific sequences?
DNA ligase
Amylase
Restriction enzyme
Protease
2.
What is the role of DNA ligase?
Joins pieces of DNA
Cuts DNA
Copies proteins
Breaks down plasmids
3.
A plasmid is:
A human chromosome
A virus coat
An enzyme
A small circular loop of bacterial DNA
4.
An organism containing a gene from another species is described as:
Cloned
Transgenic
Diploid
Mutant
5.
Why can bacteria make human insulin?
The genetic code is universal
Bacteria have a pancreas
Insulin is a bacterial protein
Bacteria have nuclei
6.
A concern about herbicide-resistant GM crops is:
They need more insecticide
They cannot grow in fields
The resistance gene may spread to wild plants
They produce insulin
7.
Which statement best describes Restriction enzyme?
An organism that contains a gene from a different species.
Something used to carry a gene into a host cell, such as a plasmid or virus.
A small circular loop of DNA found in bacteria, used as a vector.
An enzyme that cuts DNA at a specific base sequence, often leaving sticky ends.
8.
Which statement best describes Vector?
A large vessel in which microorganisms are grown in controlled conditions to make a product.
Something used to carry a gene into a host cell, such as a plasmid or virus.
An organism that contains a gene from a different species.
A small circular loop of DNA found in bacteria, used as a vector.
9.
Which statement best describes Sticky ends?
Short single-stranded overhangs of DNA left by some restriction enzymes, which pair with complementary sticky ends.
Changing the genetic material of an organism, usually by inserting a gene from another organism.
Something used to carry a gene into a host cell, such as a plasmid or virus.
An enzyme that cuts DNA at a specific base sequence, often leaving sticky ends.
10.
Which statement best describes Genetic modification?
Changing the genetic material of an organism, usually by inserting a gene from another organism.
An enzyme that joins pieces of DNA together by sealing the sugar-phosphate backbone.
An organism that contains a gene from a different species.
An enzyme that cuts DNA at a specific base sequence, often leaving sticky ends.
