Takeaways

• 😀 Conventional biotechnology is simple, using basic tools and methods like fermentation without sterilization.
• 😀 Modern biotechnology involves advanced tools, research-driven applications, mass production, and sterilization processes.
• 😀 Cloning is a method of reproducing individuals vegetatively, such as embryo cloning and somatic cell nuclear transfer, with Dolly the sheep as a famous example.
• 😀 IVF (In Vitro Fertilization) is a technique where sperm and eggs are combined outside the body, while ICSI (Intracytoplasmic Sperm Injection) involves injecting sperm directly into the egg.
• 😀 IVF is used when the egg has issues, while ICSI is used when the sperm has trouble fertilizing the egg.
• 😀 Somatic cell nuclear transfer, exemplified by Dolly the sheep, involves transferring a donor's cell nucleus into an egg cell to create a genetically identical organism.
• 😀 Dolly the sheep experienced premature aging and died at 6 due to the aging of the somatic cell nucleus she carried.
• 😀 Tissue culture is a plant propagation method based on totipotency, allowing a plant cell to grow into a complete individual.
• 😀 Recombinant DNA technology involves combining DNA from two different organisms, like in the production of insulin using bacteria.
• 😀 Monoclonal antibodies are antibodies produced by hybrid cells (hybridomas) and are used to target specific antigens, often in medical applications like diagnostics and treatments.

Q & A

What is the difference between conventional and modern biotechnology?

Conventional biotechnology uses simple tools and methods without sterilization and is based on fermentation processes. Modern biotechnology, on the other hand, uses advanced equipment, complex processes, and sterilization, with mass production capabilities and research-driven applications.

What is the role of fermentation in conventional biotechnology?

Fermentation is a core principle in conventional biotechnology. It is a process where microorganisms, such as bacteria or yeast, break down substances like sugars in the absence of oxygen, producing useful products such as alcohol or antibiotics.

How does IVF (In Vitro Fertilization) work?

In IVF, sperm and egg are combined outside the human body in a laboratory. The fertilized egg, or embryo, is then implanted into the mother's womb for pregnancy to occur. This method is often used when there are fertility issues in either the sperm or egg.

What is the difference between IVF and ICSI in fertility treatments?

In IVF, sperm and egg are placed together in a petri dish to allow natural fertilization. In ICSI, a single sperm is directly injected into the egg, which is typically used when the sperm quality or count is a concern.

What is somatic cell nuclear transfer and how was it used with Dolly the sheep?

Somatic cell nuclear transfer involves transferring the nucleus from a donor's somatic cell (e.g., mammary cell) into an egg cell that has had its nucleus removed. Dolly the sheep was cloned using this method, resulting in an organism genetically identical to the donor sheep.

What is the process of creating a transgenic organism using recombinant DNA?

In recombinant DNA technology, the DNA from different organisms is combined. For example, in insulin production, the gene for insulin from humans is inserted into a bacterium's plasmid. The modified bacterium is then cultured to produce the hormone, which is harvested for medical use.

What is the significance of totipotency in plant tissue culture?

Totipotency refers to the ability of a single plant cell to regenerate into a whole new plant. This property is used in plant tissue culture to grow new plants from small tissue samples, ensuring that the new plants are genetically identical to the original.

How are monoclonal antibodies produced?

Monoclonal antibodies are produced by fusing mouse immune cells (which produce antibodies) with cancer cells, creating hybridoma cells. These hybridoma cells are capable of producing large quantities of a single, specific antibody that can target a particular antigen.

What is the main difference between monoclonal antibodies and vaccines in terms of production?

Monoclonal antibodies are produced using animals or cell cultures, whereas vaccines are produced by directly injecting antigens into the human body, prompting the body to generate antibodies against the disease.

What are the ethical concerns surrounding cloning, such as in the case of Dolly the sheep?

Ethical concerns about cloning include issues related to animal welfare, the risk of premature aging or health problems in clones (as seen with Dolly), and the potential for human cloning. These concerns have led to debates about the limits of biotechnology in cloning applications.
