To solve this problem, we need to complete the flow chart on the central dogma of molecular biology. Let's analyze each part:$\newline \bullet$(a) DNA: The process that involves DNA making a copy of itself is called Replication.$\newline \bullet$(b) The process of synthesizing mRNA from DNA is called Transcription.$\newline \bullet$(c) The process of synthesizing a protein from mRNA is called Translation.$\newline \bullet$(d) The final product of translation is a Protein.$\newline$Now, let's complete the flow chart:$\newline (a) \rightarrow$Replication$\newline (b) \rightarrow$Transcription$\newline (c) \rightarrow$Translation$\newline (d) \rightarrow$Protein$\newline$This corresponds to Option 3.
