Explain an advantage the polymerase chain reaction (PCR) has for DNA research.

A rare disease is now understood to be caused by a single mutant gene. When the researcher learns that the gene encodes a ________, he says “Oh good! We may be able to treat the disease with recombinant protein produced in E. coli and delivered by injection.”

Two strands of DNA that have been cut by an endonuclease can be sealed together by a(n)

Vertebrate cells possess a protein that binds to clusters of 5-methylcytosine and ensures the gene will stay in the “off” position. This control of gene regulation is a result of

The most recent techniques developed in the biological sciences allow the manipulation of DNA with the ultimate goal of intervening directly with the ________ fate of organisms.

Can you predict how alternative splicing may lead to an economy of genes? Do you need a different gene for every protein that the cell can produce?

In a small population of cockroaches living in your kitchen, only a few roaches mate in one year.  This can lead to random changes in allele frequency in the population through ________
