Solution
The central dogma of molecular biology states that DNA is a template for all RNA production.
Explanation:
The central dogma of molecular biology describes the fundamental flow of genetic information within a biological system. It establishes that DNA serves as the master template for producing all types of RNA (including mRNA, tRNA, and rRNA) through the process of transcription. This RNA then acts as a messenger to guide the synthesis of proteins during translation. While the dogma also includes DNA replication (DNA making more DNA), its core principle is the unidirectional flow from nucleic acids to proteins.
