Verified step by step guidance

Understand the central dogma of molecular biology, which describes the flow of genetic information in cells. It states that genetic information is transferred from DNA to RNA and then to protein.

Recognize that DNA serves as the template for RNA synthesis in a process called transcription. This involves the enzyme RNA polymerase creating a complementary RNA strand from the DNA template.

Next, RNA acts as the template for protein synthesis in a process called translation. During translation, ribosomes decode the messenger RNA (mRNA) sequence to assemble amino acids into a polypeptide chain, forming a protein.

Eliminate incorrect options based on the central dogma. For example, DNA does not directly convert into protein, nor does protein serve as a template for RNA or DNA synthesis.

Select the correct answer: DNA \\(\rightarrow\\) RNA \\(\rightarrow\\) Protein, as this accurately represents the flow of genetic information according to the central dogma.
