Which of the following is NOT part of the central dogma?

The central dogma of molecular biology describes the flow of genetic information within a biological system. This process typically involves the transfer of information from DNA to RNA, which is then translated into proteins. In this framework, DNA serves as the template for transcription into RNA, and RNA is used as a template for translation into protein.

Carbohydrates, while essential biomolecules involved in various biological functions such as energy storage and cellular structure, do not play a direct role in this flow of genetic information described by the central dogma. They are not involved in the processes of transcription or translation that underlie the synthesis of proteins from nucleic acid templates. Thus, carbohydrates are correctly identified as not being part of the central dogma.
