Science — Introduction to Biotechnology and Its Foundations + 6 more topics

Biotechnology is simply the application of biological organisms, systems, or processes for industrial, agricultural, medical, or environmental purposes. It's not just about cutting-edge science; it has ancient roots.

The Central Dogma describes the fundamental process by which genetic information is expressed in all living organisms. It's a one-way street for information flow, generally from DNA to RNA to protein.

DNA, or deoxyribonucleic acid, is the blueprint of life. It's a complex molecule that carries all the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses.

You've probably heard of DNA – it's the famous double helix. Well, genes are specific sections of that DNA. Each gene carries the code, or "recipe," for a particular trait or function, like eye color, blood type, or how to make a specific protein.

Chromosomes are highly organized structures found inside the nucleus of almost every cell in your body. They're essentially tightly wound bundles of DNA. If you stretched out all the DNA from a single human cell, it would be about 2 meters long! Chromosomes keep this incredibly long strand of DNA compact and protected, making it manageable during cell division.

Gene expression involves two main steps:
1. Transcription: DNA's genetic information is copied into an RNA molecule.
2. Translation: The RNA molecule's information is used to synthesize a protein.

Biotechnology heavily relies on understanding and manipulating cells. We're generally interested in two main types of cells: prokaryotic and eukaryotic.
