Decoding DNA: The Blueprint of Life

The video tutorial explains that genes carry genetic information and are located on chromosomes. Genes are segments of DNA, which is the molecule containing the genetic code for all life forms. DNA is structured as a double helix and is stored in the cell nucleus. It consists of four bases: adenine, guanine, cytosine, and thymine. The unique combination of these bases results in genetic variability among individuals. DNA can replicate itself, ensuring that each cell in the body has the same genetic information. The tutorial concludes with a review and quiz questions to reinforce learning.
