Describe how DNA is like a recipe ? What happens if DNA changed abnormally?
plz help :'(

Your DNA is like the cookbooks of your cell. So that would mean each cell has two editions of 23 different cookbooks. In our example, each recipe in the cookbooks is like a gene. For humans, this cookbook collection would need to contain at least 25,000 recipes.

If DNA changed abnormally, it could lead to an disease.
