polymerize in the 3 ' to $5^{\prime}$ direction and replication fork
prove semi-conservative nature of DNA replication
polymerize in the $5^{\prime}$ to 3 ' direction and explain 3' to 5' DNA replication
result in transcription.
Solution
Okazaki fragments in DNA are linked up by the enzyme DNA ligase after replacing the RNA primers with deoxyribonucleotides after replacing the $\mathrm{RNA}$ primers with deoxyribonucleotides solution of the Okazaki fragments in DNA chain growth. Replication occurs always in 5'-3' direction. However, Okazaki fragments are synthesized on 3'-5' DNA template, join to form lagging strand which grows in $3^{\prime}-5^{\prime}$ direction.
