Question 1
Which of the following proteins appears to be cis-acting?
◦ The
Agrobacterium virG protein
◦ The φX174 A protein
◦ The adenovirus terminal protein
◦ The F plasmid tra proteins
◦ The plasmid ParA protein
Question 2
Why is rolling circle DNA replication used by many bacteriophages?
◦ It can only generate single-stranded copies, and many phage genomes are single-stranded.
◦ It is an efficient way to generate a large number of daughter molecules.
◦ It makes use of all the same proteins as bacterial chromosome replication but is faster.
◦ It simultaneously degrades bacterial chromosomal DNA.
◦ It allows transcription of phage genes to occur at the same time as they are replicated.
