Learn how to create a DNA MOLECULE
Posted on December 31, 2012
Your body produces billions of new cells every day. Each time one of your cells divides, it must first copy the genetic information contained within its nucleus. Copying the genetic information in one cell using this activity would take more than 95 years*, yet molecular machines in your cells accomplish this feat in about 6 to 8 hours.click here for learning how you can create a DNA MOLECULE .
DNA TO PROTEIN
Posted on December 31, 2012
DNA is made of four simple building blocks, yet it contains all of the information necessary to build an organism. Segments of DNA called genes contain specific instructions that make each individual unique.Cellular machinery uses genes as instructions to assemble proteins.click here to See how cells "read" the information in a DNA sequence to build a protein, then build one yourself!
