The following reaction shows the formation of a cyclic acetal from a cyclic hemiacetal by the addition of methanol and the removal of water. In this case, the oxygen shown has been tagged with oxygen-18. After the formation of the cyclic acetal, at what position would you expect to find the oxygen-18 atom?
List other types of errors that occur during replication of
DNA.7. Explain why the formation of mismatched base pairs during
replication can cause a mutation.
1. Explain why bacterial behaviors such as biofilm formation,
quorum sensing, and endospore formation can promote disease
