In bacteria, DNA replication begins at a site on the chromosome known as the ________________. 4. DNA replication requires enzymes, list the key enzymes involved in the process and their function. 5. What is the enzyme that builds a complementary strand of DNA? Which direction does it build a new strand? 6. When DNA replication occurs there is the synthesis of a leading and lagging strand. What do these terms mean? Use the space below to draw replication of a strand of DNA and indicate which strand Is the leading strand and which is the lagging strand. 7.
