Genetic Engineering and Recombinant DNA in Modern Biology

The video tutorial covers essential concepts in genetics, including the structure and function of genes and proteins. It explains genetic modification, where genes from one organism are transferred to another, creating recombinant DNA and transgenic organisms. The tutorial details the tools used in genetic engineering, such as restriction enzymes and DNA ligases, and discusses vectors like plasmids and viruses for DNA transfer. These techniques have broad applications across various organisms, from bacteria to plants and animals.

What is a gene primarily responsible for?

• Coding for proteins
