A
is the use of recombinant DNA vectors to alter the expression of a particular gene, either by introducing mutations in a gene, or by eliminating the expression of a certain gene by deleting a part or all of the gene sequence from the genome of an organism.
Gene targeting
Scientists are working to develop a way to make crops resistant to frost due to drops in temperature in the winter in order to allow certain crops to grow into the winter months that normally would not. They would like to try inserting genes from arctic fish that help them survive the icy waters into the crops to see if this would allow for the crops to withstand lower temperatures. Which technique could be used first to locate the specific gene they are looking for in the arctic fish?
Responses

DNA fingerprinting
Which of the following statements about genomic analysis is FALSE?
Responses
DNA fingerprinting can be used to differentiate between identical twins who otherwise could not be told apart just by their phenotypes.

Responses
Genetic screening
