Pigs to the

Rescue

Using CRISPR, a hot new genome-editing tool,

scientists hope to create a steady stream of transplant

organs—from pigs.

◆ (^) Describe the structure of DNA, using appropriate terminology.
◆ (^) Use the base-pairing rules to determine a complementary strand of DNA based on a
given template strand.
◆ (^) Describe how the genome editing tool CRISPR-Cas9 works.
◆ (^) Label a diagram of DNA replication, identifying the location of each step in the
process.
◆ (^) Identify when PCR and gene sequencing technology should be used in an
experiment.
◆ (^) Explain the cause of DNA replication errors, and describe how they are repaired.
◆ (^) Give an example of a mutation and its potential effects on an organism.
