The mechanism of DNA replication is studied in an E. coli replication fork. Which is a property of Okazaki pieces in an E. coli replication fork?

#Unit 3. Fundamental Processes
  1. Okazaki pieces are joined together by DNA polymerase I to form a long chain.

  2. Okazaki pieces are polymerized in the 3′→ 5′ direction by DNA polymerase III.

  3. An Okazaki piece for the leading strand is polymerized to a length of 1000-2000 nucleotides.

  4. An Okazaki piece for the lagging strand has a base sequence complementary to its template.
