Textbook Question
Chapter 23.6, Problem 1CR
Q How is it possible for aphids to feed only on the carbohydrate-rich but nutrient-poor sap of phloem vessels in plants? Why do symbionts that are transmitted horizontally show less genome reduction, as opposed to the significant genome reduction observed in heritable symbionts?

The figure below shows the life cycle of the fungus Neurospora. The adult stage of the Neurospora is a multicellular haploid.
Neurospora has an arginine amino acid synthesis pathway shown below. Suppose I have a Neurospora strain that has a mutation such that it will not grow unless I supplement the media (food) with arginine (but not with citrulline or ornithine). What gene is mutated? Explain your reasoning.
Most phages that use DNA to propagate work by hijacking host bacterial machinery including RNA Polymerase. Scientists found that treatment of jumbo bacteriophage PhiKZ with Rifampicin did not stop the phage from propagating. What is allowing for the survival of this phage?
How does core genome and pan genome contributes to the genome of C.diphtheria.
