6. DNA Basics DNA is genetic material responsible for an organism’s hair color, body structure, enzyme production etc. DNA is genetic material responsible for an organism’s hair color, body structure, enzyme production etc.

7. DNA Basics DNA is located in the nucleus of a cell. DNA is located in the nucleus of a cell. For the information in DNA to leave the nucleus, it must be turned into mRNA. This process is called transcription. For the information in DNA to leave the nucleus, it must be turned into mRNA. This process is called transcription. When the cell divides, the DNA is copied in the process of replication. This is done so that the two new cells have the same genetic information.
