Final answer:
Option A) DNA replication is a highly accurate process that occurs without many mistakes. It is bidirectional and discontinuous, with the rate of replication being quite rapid.
Step-by-step explanation:
DNA replication is a highly accurate process that occurs without many mistakes. However, occasional mistakes can occur, such as a DNA polymerase inserting a wrong base. Repair mechanisms are in place to correct these mistakes. In rare cases, mistakes are not corrected, leading to mutations.
The rate of DNA replication is quite rapid, with approximately 1000 nucleotides added per second. The process is bidirectional, meaning it occurs in both directions from a single origin of replication. It is also discontinuous, with the lagging strand replicated in short stretches, resulting in the formation of Okazaki fragments
