Sample Oral Examination Questions

These questions merely indicate the content of oral examinations. Exams are not limited to these questions. In general, and throughout the exams where appropriate, be prepared to speak about the relevance of the scientific material to philosophical, ethics, metaphysical, and theological questions (we call these “boundary issues”).

Explain why the periodic table arranged the way it is.

Describe the role of H+ bonding in macromolecular structure. Give two examples in:

  • Protein structure

Summarize the work of Gregor Mendel. What two main principles of genetics were derived from his work (Independent Assortment and Segregation)? What is the molecular biological basis for these principles? What is an allele?

In mice there are two separate alleles for coat color and hair length. The dominant alleles are gray coat with short hair and the recessive alleles are tan coat with long hair. Work out a cross between a homozygous dominant mouse with a homozygous recessive mouse in the P generation and predict the allelic distribution in the F1 and F2 generations.

Examination of Mathematics Segments M2, M3: Vector Calculus

What is a vector space? linear combination? linear dependence and independence? basis? dimension?

How do we define a metric on a vector space? Examples of metrics on R2, including graphs of length-1 vectors in Euclidean and Lorentzian metrics.

How do we use a metric to speak of length of vectors and angle between vectors? What is an orthonormal basis? coordinate system? How do we represent the same vectors in more than one coordinate system?

What is flux? circulation?

What is Gauss's theorem (divergence theorem)? Stokes’ Theorem?

State Maxwell’s equations in differential and integral form. Show how to derive the integral from the differential form, and vice versa.

Explain the connection between Maxwell’s equations and the basic results of electrostatics. Derive Coulomb’s law from Maxwell I and Ampere’s Law from Maxwell II.

Write down the field equation for Electromagnetic radiation. (Bonus: derive it from Maxwell’s equations!) Explain the velocity of electromagnetic radiation from the field equation.
