 15.  Can you differentiate between transfection and transduction?

Transfection is the direct introduction of foreign DNA into eukaryotic cells using chemical or physical methods. In fact, transduction involves the transfer of genetic material through viral vectors, where viruses deliver foreign DNA into the host cell’s genome.

16. What are the bacteria that we can consume?

Some bacteria that are safe for consumption include certain probiotic strains like Lactobacillus and Bifidobacteria. Actually, they are commonly found in yogurt and fermented foods.

17. How can you define Bio-ethics?

Bioethics is the study of ethical issues and dilemmas arising from advances in biology, medicine, and biotechnology. Basically,it addresses moral considerations related to human life, health, research, and the environment.

18. What is drug targeting?

Drug targeting is a strategy to deliver medications selectively to specific cells, tissues, or organs in the body while minimizing their effects on non-targeted areas. It aims to enhance the drug’s efficacy, reduce side effects, and improve treatment outcomes.

19. How can you say that biotechnology has generated a variety of novel therapeutic agents?

Biotechnology has generated a variety of novel therapeutic agents through advances in genetic engineering, recombinant DNA technology, and biopharmaceutical production. Also, these innovations have led to the development of biologics, gene therapies, monoclonal antibodies, and personalized medicines.

20. Tell us what you know about cytokines.

Cytokines are small proteins that play crucial roles in cell signaling and communication within the immune system. Basically, they regulate immune responses, inflammation, cell growth, and differentiation, acting as key mediators in various physiological and pathological processes in the body.

21 What is the difference between type I and type II hypersensitivity?

Type I hypersensitivity is an immediate allergic reaction involving IgE antibodies and the release of histamine, causing rapid inflammation and symptoms like hives and anaphylaxis. Type II hypersensitivity is an antibody-mediated reaction where antibodies target specific cells or tissues, leading to cell destruction or dysfunction, such as in autoimmune diseases and certain drug reactions.
