Exploring the Basics of Genes and Genetic Modification

The video explains what genes are and their role in coding for proteins. It describes how DNA is composed of nucleotides and how genes, as segments of DNA, contain instructions for making proteins. These proteins interact to form various structures and functions in the body. The video also highlights genetic similarities across species and discusses genetic engineering, where genes from one organism can be inserted into another to produce desired proteins. The basic DNA language is shared among all living things, supporting the idea of common ancestry.

What are the four types of nucleotides in DNA?
