Which enzyme could be used to join two DNA fragments?
DNA ligase
DNA polymerase
DNA recombinase
DNA endonuclease
Which statement about recombinant DNA is true?
All restriction endonucleases generate blunt end fragments.
Hydrogen bonds between base pairs are very strong.
Restriction endonucleases cut both strands of DNA at the same time.
Sticky ends prevent DNA ligase activity.
Why are plant cells, as opposed to animal cells, particularly useful as hosts for recombinant DNA?
Animal cells cannot be cultured.
Plant cells can make totipotent stem cells.
Plant cells have reverse transcriptase.
Plant cells have plasmids
Genetic engineering involves
cutting out a DNA sequence.
changing a DNA sequence.
reinserting DNA into living organisms.
all of the above
A recombinant plasmid gets inside a bacterial cell by
. hybridization
radiation
transformation
recombination
A DNA molecule produced by combining DNA from different sources is known as
a mutant
a change
strange DNA
recombinant DNA
The process of making changes in the DNA code of living organisms is called
selective breeding
genetic engineering
inbreeding
hybridization
Small circular pieces of DNA found inside bacteria in addition to their chromosome is called
a DNA
a clone
RNA
a plasmid
What does it mean to “clone a gene”?
make many copies of the gene
remove the gene
change the gene
destroy the gene
DNA from a human has been inserted into a bacterial plasmid and reinserted back into the bacterium. The bacterium now contains both human DNA and bacterial DNA. The bacterium is now considered a
mutation
clone
PCR
transgenic organism
