In genetic material, what type of molecule is crucial for inheritance of traits?

  1. Glucose

  2. DNA

  3. Proteins

  4. Lipids

The correct answer is: DNA

DNA, or deoxyribonucleic acid, is the molecule responsible for storing and passing on genetic information from one generation to the next. It contains the necessary instructions that dictate the development and functioning of all living organisms. Glucose, proteins and lipids may play important roles in various biological processes, but they are not the primary molecule involved in inheritance of traits. Therefore, they are incorrect options for this question.
