Answer:
Macromolecules are "large" molecules, such as DNA, RNA, and proteins. During gel electrophoresis, the macromolecules (DNA in the forensics example above) are loaded into a gel. Then a current is applied across the gel. The result is a separation of the macromolecules, based on mass.Understanding macromolecules is crucial in forensic analysis. Macromolecules like DNA, proteins, and carbohydrates provide valuable insights into biological materials. DNA analysis helps identify individuals and link suspects to crime scenes. Protein analysis aids in identifying substances and estimating deposition time. Macromolecules are also vital in forensic toxicology, serology, and entomology, helping determine causes of death, evidence of drug consumption, and postmortem intervals. Overall, understanding macromolecules allows for accurate analysis of biological evidence, aiding in investigations and court presentations.
