You are working in a molecular biology lab and, unbeknownst to you, your lab partner left the foreign genomic DNA you are planning to clone on the lab bench overnight instead of storing it in the freezer. As a result, it was degraded by nucleases, but still used in the experiment. The plasmid, on the other hand, is fine. What results would you expect from your molecular cloning experiment?

The streamlined bodies seen in sharks, tuna, and dolphins best relate to

Which of the following populations has violated the conditions of Hardy-Weinberg Equilibrium?

Does alternative gene splicing increase or decrease the flexibility of gene expression? Explain your answer.

Does alternative gene splicing increase or decrease the flexibility of gene expression? Explain your answer.

During development in the mother’s uterus, human embryos have pharyngeal pouches (sometimes called gill slits) that later develop into various glands. Fish also have pharyngeal pouches as embryos, but these develop into gills. The best explanation for why human and fish embryos develop pharyngeal pouches is

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

New drugs are being developed that decrease DNA methylation and prevent the removal of acetyl groups from histone proteins. Explain how these drugs could affect gene expression to help kill tumor cells.

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.”
