1. DNA → Carbohydrates → Proteins 2. DNA → RNA → Proteins 3. DNA → RNA → Carbohydrates 4. Amino acids → Proteins → DNA

The central dogma of molecular genetics states that the genetic information flows from

1. DNA \(\rightarrow\) Carbohydrates \(\rightarrow\) Proteins

2. DNA \(\rightarrow\) RNA \(\rightarrow\) Proteins

3. DNA \(\rightarrow\) RNA \(\rightarrow\) Carbohydrates

4. Amino acids \(\rightarrow\) Proteins \(\rightarrow\) DNA

Best answer

Answer: 2. DNA \(\rightarrow\) RNA \(\rightarrow\) Proteins

Key idea: the central dogma: DNA is transcribed to mRNA, which is translated to protein.
