Biotechnology primarily utilizes the biological molecules and systems from organisms, especially their DNA. Here's how:
DNA and Genes: DNA contains genes, which are like recipes that tell cells how to make proteins. In biotechnology, scientists take specific genes from one organism and put them into another to give it new abilities. For example, they might put a gene from a jellyfish into a plant to make it glow.
Proteins and Enzymes: Proteins made from DNA instructions do important jobs, like breaking down food or fighting off germs. In biotechnology, proteins and enzymes are used to create medicines (like insulin for diabetes) or help in industrial processes (like enzymes in laundry detergent).
Cells and Microorganisms: Whole cells, like bacteria or yeast, are used to make products. For example, yeast is used in biotechnology to make bread rise and to produce biofuels.
Viruses and Plasmids: These are used as tools to carry new genes into cells. For instance, in gene therapy, modified viruses deliver healthy genes to fix genetic disorders.
Overall, biotechnology uses parts of living things—mainly their DNA, proteins, and cells—to make useful products and solve problems.

A blood sample was collected from a crime scene and analyzed using DNA fingerprinting. The DNA profiles of the crime scene sample and three suspects (Suspect 1, Suspect 2, and Suspect 3) are shown below.
Based on the DNA profiles, which suspect is most likely to have been present at the crime scene? First look at the crime scene, then compare to the suspect to see the closest match.
