Genetic Engineering MCQs with Answers

Welcome to the Genetic Engineering MCQs with Answers. In this post, we have shared Genetic Engineering Online Test for different competitive exams. Find practice Genetic Engineering Practice Questions with answers in Biology Tests exams here. Each question offers a chance to enhance your knowledge regarding Genetic Engineering.

Genetic engineering is a cutting-edge technology that involves modifying an organism’s DNA to achieve specific traits or functions. This field encompasses various techniques for altering genetic material, including gene editing, gene cloning, and recombinant DNA technology. By manipulating genes, scientists can introduce new traits, enhance existing ones, or correct genetic defects.

One of the most notable methods in genetic engineering is CRISPR-Cas9, a revolutionary tool that allows for precise and efficient gene editing. CRISPR-Cas9 has transformed research by enabling targeted modifications in the genome, facilitating advances in areas such as medicine, agriculture, and biotechnology.

In medicine, genetic engineering is used to develop gene therapies that aim to treat or cure genetic disorders by correcting faulty genes. This approach has shown promise for conditions like cystic fibrosis and muscular dystrophy. Additionally, genetically modified cells are employed in immunotherapies to target and destroy cancer cells.

In agriculture, genetic engineering has led to the creation of genetically modified (GM) crops with enhanced traits such as pest resistance, improved nutritional content, and increased yield. These innovations address food security challenges and reduce the need for chemical pesticides.

In biotechnology, genetic engineering contributes to the production of pharmaceuticals, biofuels, and biodegradable materials. By engineering microorganisms, scientists can produce valuable substances more efficiently and sustainably.

Overall, genetic engineering offers transformative potential but also raises ethical and safety concerns that require ongoing research and regulation.
