What is responsible for the continuity of genetic information across generations?

Proteins
DNA
RNA
Enzymes

The correct answer is: DNA

DNA, or deoxyribonucleic acid, is responsible for the continuity of genetic information across generations. This molecule contains the genetic information necessary for the development and function of all living organisms. Proteins cannot store genetic information as reliably as DNA, and are not involved in the replication and transmission of genetic information. RNA, while involved in the process of protein synthesis, is unable to maintain and transmit genetic information across generations. Enzymes are also not responsible for the continuity of genetic information, as they are molecular catalysts that help facilitate biochemical reactions but do not carry genetic information. Therefore, the correct answer is B.
