The replication process involves the following steps: (I) The enzyme DNA-dependent DNA poly merases catalyse the polymerisation of DNA strand. (II) The lagging strand is synthesized in frag ments known as Okazaki fragments, which are later joined by the enzyme DNA Ligase. (III) The origin of replication serves as the recognition site for DNA polymerase and also it provides the site for attachment of RNA primer. (IV)The structural gene coding for a partic ular protein is flanked by the promoter and terminator. Choose the correct option:
