The assertion that DNA replication in prokaryotes is bidirectional is true. Bidirectional replication means that DNA synthesis proceeds in both directions from the origin of replication, creating two replication forks that move in opposite directions. The reason given for this assertion is also true. Prokaryotes typically have a single, circular chromosome, unlike eukaryotes, which have linear chromosomes. The presence of a single origin of replication on the circular chromosome leads to bidirectional replication. Hence option 1 is the correct answer.
