LIFE SCIENCE

Detailed explanation-1: -DNA is analogous to a cookbook that contains many recipes to make meals. DNA makes not meals (of course!) but proteins. A gene, a segment of DNA, is analogous to a specific recipe in the cookbook. Thus each gene makes a specific protein.

Detailed explanation-2: -DNA is information. Think of DNA as a collection of cookbooks that contain all the recipes for making and running living things like worms, plants, birds, and people.

Detailed explanation-3: -Think of your DNA as a giant cookbook: it contains all of the recipes that your cells need to use in order to function. mRNA’s job is to copy a recipe from the cookbook and then bring it to the part of the cell that uses it to build a protein.
