The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step 1: Understanding the Assertion The assertion states that "The enzyme involved in the continuous replication of DNA strand is DNA polymerase." - **Analysis**: DNA polymerase is indeed the enzyme responsible for synthesizing new DNA strands during replication. It adds nucleotides to the growing DNA chain in a 5' to 3' direction, which is essential for DNA replication. ### Step 2: Understanding the Reason The reason states that "The polarity of the template strand is 3' to 5'." - **Analysis**: While it is true that the template strand runs in a 3' to 5' direction, this does not directly explain why DNA polymerase is involved in continuous replication. DNA polymerase synthesizes new DNA in the 5' to 3' direction, which means it uses the template strand that is oriented in the opposite direction (3' to 5'). ### Step 3: Evaluating the Relationship Between Assertion and Reason Now we need to determine if the reason correctly explains the assertion. - The assertion is correct: DNA polymerase is involved in continuous replication. - The reason is also correct: the template strand has a polarity of 3' to 5'. - However, the reason does not provide a correct explanation for the assertion since it does not clarify the role of DNA polymerase in the context of replication. ### Step 4: Conclusion Based on the analysis: - The assertion is true. - The reason is true but does not explain the assertion. Therefore, the correct answer is option C: "The assertion is correct but the reason is wrong."

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:
