1, the differences and relations between traditional biotechnology and modern biotechnology

What a broad question. I'll just talk about it from the study of aquatic products.

Difference: the research level of traditional biotechnology is at the level of cells or tissues, while the research level of modern biotechnology is at the molecular level.

Connection: The research of modern biotechnology is based on traditional biotechnology. The research of modern biotechnology can promote the research of traditional biotechnology.
