McArdle Disease is a form of anemia that can be treated with regular iron infusions. The disorder is caused by a mutation in a gene, NX2, that results in a a mis-folding of a cell surface protein, which affects the body’s ability to transport iron. Individuals with this disorder are resistant to a virus that uses the same cell surface protein to enter cells. This scenario illustrates:

DNA acquires more mutations in:

Which of the following situations would NOT affect gene dosage?

A cDNA:

Which of the following results in an increase in genetic variation?

A gene encodes three related yet slightly different proteins. All are perfectly functional. What is most likely to account for this scenario?

In order to overcome some technology barriers to fulfill the promise of precision medicine:

How does genome editing through CRISPR/CAS work?

Tropism is best defined by a virus’s ability to:

In the gene chip method of genotyping, the fragments are [blank1], which [blank2].
