Question 3 1 pts How would exchanging the CW ter sites with the CCW ter sites alter DNA replication? ODNA replication and termination would proceed as normal O CW forks would stop at CCW fork traps & CCW forks would stop at CW fork traps Neither CW or CCW forks would stop the replication forks The chromosome would not be completely replicated Replication would abort Question 4 1 pts Which of the following is true about...

Yet, all the cells in your body contain the same
genes (and same alleles). The difference across cell types
is that genes get selectively expressed (turned on or off)
based on the proteins needed for cellular function given their
environment.
