Multiple Choice

Some viruses can be crystallised and their structures analysed. One such virus is yellow mottle virus, which infects beans. This virus has a single-stranded RNA genome containing about 6,300 nucleotides. Its capsid is 25-30 nm in diameter and contains 180 identical capsomeres. If the yellow mottle virus begins its infection of a cell by using its genome as mRNA, which of the following would you expect to be able to measure when analysing the reproduction of this virus?

• A) replication rate
• B) transcription rate
• C) translation rate
• D) formation of new transcription factors
