Question
The prolate form of this shape is characterized by the Q number. For 10 points each:
[10h] Name this shape. Caspar-Klug theory states that the number of “quasi-equivalent” subunits creating this shape is characterized by an integer T that equals h squared plus hk plus k squared, for non-negative integers h and k.
ANSWER: icosahedron [or icosahedra]
[10e] In “spherical” viruses, these components are typically icosahedron-shaped. These components are the protein shells of a virus containing its genetic material and are sometimes enclosed within an envelope.
ANSWER: viral capsids
[10m] This prolate virus elongates by having different T values for different portions of the capsid. DNA ligase used in experiments is isolated from this model virus that notably does not reproduce by the lysogenic cycle.
ANSWER: Escherichia virus T4 [or T4 virus; prompt on T-even bacteriophage; prompt on bacteriophage]
