Reason: It involves transfer or replacement of genes to create recombinant DNA.

A

B

If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion.

C

If Assertion is true but Reason is false.

D

If both Assertion and Reason are false.

Text Solution

AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Assertion**: The assertion states that genetic engineering involves the alteration of the genetic makeup of cells through deliberate and artificial means. This means that scientists intentionally modify the DNA or RNA of an organism. 2. **Understanding the Reason**: The reason provided explains that genetic engineering involves the transfer or replacement of genes to create recombinant DNA. This indicates that through genetic engineering, genes from one organism can be inserted into another organism's DNA, resulting in a new combination of genetic material. 3. **Linking Assertion and Reason**: Both the assertion and reason are closely related. The assertion describes the overall process of genetic engineering, while the reason provides a specific mechanism (transfer or replacement of genes) that explains how this alteration occurs. 4. **Evaluating the Truth of Both Statements**: - The assertion is true because genetic engineering does involve intentional changes to genetic material. - The reason is also true because the creation of recombinant DNA is a fundamental aspect of genetic engineering, achieved through the transfer or replacement of genes. 5. **Conclusion**: Since both the assertion and reason are true, and the reason correctly explains the assertion, we can conclude that the answer is that both statements are correct and the reason is the correct explanation of the assertion. **Final Answer**: Both the assertion and reason are true, and the reason is the correct explanation of the assertion. ---

    [A]: Genetic engineering is the use of tech- nology to alter the genome of a cell for the benefit of we people. [R]: Here foreign gene is inserted into the cell to get desirable product

    Assertion: Genetic engineering overcomes the drawbacks of tradiational hybridisation. Reason: Genetic engineeing involves creation of a recombinant DNA and introduce the desirable genes into target organisms.

    Assertion : Translocations involve shifting, not deleting or adding genetic material which can cause chromosomal defects when gametes are formed. Reason : Translocation involve transfers of genetic material between homologous chromosomes.

    The term biotechnology refers to the use of living organisms or their products to modify human health and their human environment. For example, 'testtube' programme, synthesis of a gene or correcting a defective gene are all part of the biotechnology. The basis of the modern biotechnology are genetic engineering and maintenance of sterile conditions. Genetic engineering is the technique that alter the chemistry of genetic material i.e. DNA and RNA, then this genetic material is introduced into host organisms, which alter the phenotype of the host organism. The specific DNA sequence where EcoRI cuts is:
