The correct Answer is:
### Step-by-Step Solution 1. **Understanding the Assertion**: The assertion states that DNA polymerase must catalyze the reaction of nucleotide polymerization with a high degree of accuracy, in addition to having a high rate of polymerization. This means that while DNA polymerase is efficient in replicating DNA, it must also ensure that the correct nucleotides are added to the growing DNA strand. 2. **Evaluating the Reason**: The reason provided explains that any mistake during DNA replication can lead to mutations. This is a crucial point because mutations can have significant consequences for the organism, including potential diseases or developmental issues. 3. **Analyzing the Relationship**: The assertion and reason are closely related. The high accuracy of DNA polymerase is necessary to prevent mutations during replication. If mistakes occur, they can result in incorrect base pairing, leading to mutations. Therefore, the reason supports the assertion. 4. **Conclusion**: Both the assertion and the reason are true, and the reason correctly explains why the assertion is important. DNA polymerase must work quickly and accurately to ensure proper DNA replication and to minimize the risk of mutations. 5. **Selecting the Correct Option**: Based on the analysis, the correct option is: - **Option A**: Both assertion and reason are true, and the reason is the correct explanation of the assertion.

Read the following paragraph and answer the questions given below , Stable equilibrium is of various types . Mechanical equilibrium is achieved when all particles are at rest and total potential energy of the system is minimum . At any stage where particles are at rest but the system is not at stable equilibrium as it can reduce its potential energy by reverting to another position, is called metastable equilibrium . Thermal equilibrium is result from the absence of temperature gradients in the system. Chemical equilibrium is obtained when no further reaction occurs between reacting substances, i.e forward and reverse rates of reaction are equal. When steam with solid iron at high temperature Fe_3O_4(s) and hydrogen gas are produced . But the reaction never goes to completion. This is because as the products are formed the reaction proceeds in reverse direction and when rate of reverse reaction is equal to rate of forward reaction , the concentration of reactants and products become constant and equilibrium is reached. The primary objective of the passage is

Assertion :- The probability of DNA polymorphism would be higher in non-coding DNA sequences. Reason : Mutations in these seuqences may not have any immediate effect in an individual's reproductive ability.

Assertion : When the DNA sequences of two people are cut using the same restriction enzyme, the length and number of fragments obtained are different for both. Reason : DNA sequence is arranged tandemly in many copy numbers which varies from chromosome to chromosome in an individual, showing high degree of polymorphism.

Assertion : Critically endangered category includes the species which have sufficient populationa at present but is undergoing depletion due to some factors. Reason : Vulnerable category includes the species which are facing very high risk of extinction in the wild an can become extinct any moment.
