Options
Transcription, Translation, Replication
Transcription, Replication, Translation
Duplication, Translation, Transcription
Replication, Transcription, Translation

Solution
Replication, Transcription, Translation
Explanation:
The Central Dogma describes the fundamental flow of genetic information within a biological system, typically following a specific three-step sequence:
- Replication: The process by which DNA makes an exact copy of itself, ensuring genetic continuity during cell division.
- Transcription: The genetic code from a DNA template is used to synthesise a complementary messenger RNA (mRNA) molecule.
- Translation: The sequence of nucleotides in the mRNA is decoded at the ribosome to assemble amino acids into a specific protein.
