Consider statements about biotechnology: 1. Genetic engineering involves altering an organism's DNA. 2. Cloning creates an exact genetic copy. 3. Tissue culture is used for plant propagation. Which are correct? MCQ with Answer and Explanation

Genetic engineering (recombinant DNA technology) involves the direct manipulation of an organism's genes using biotechnology to alter its characteristics. Cloning is the process of producing genetically identical copies of a biological entity, such as a gene, cell, or entire organism. Tissue culture (micropropagation) is a technique used to grow plant cells, tissues, or organs in a sterile nutrient medium, allowing for the rapid, large-scale propagation of plants from a small explant. All statements are correct.
