Which statement best describes how replication, transcription, and translation are similar and different?

• A. Replication, transcription, and translation are all processes where nucleic acids serve as templates to produce different biopolymers. Hydrogen bonding is crucial in aligning subunits correctly for these processes. Replication involves copying DNA, transcription converts DNA into mRNA, and translation uses mRNA to assemble proteins. Replication and transcription occur in the nucleus, while translation occurs in the ribosomes.
• B. Replication, transcription, and translation are all processes that exclusively use proteins as templates to synthesize nucleic acids. Replication involves making RNA copies of proteins, transcription synthesizes DNA from RNA, and translation creates new DNA molecules. These processes occur in the mitochondria and use unique enzymes not found elsewhere in the cell.
• C. Replication, transcription, and translation are similar in that they all happen in the mitochondria. Replication creates proteins from DNA, transcription makes RNA from proteins, and translation produces DNA from mRNA. All these processes involve the same type of bonding and happen in the cytoplasm.
• D. Replication, transcription, and translation all involve converting DNA into different forms of RNA. Replication synthesizes mRNA from DNA, transcription creates tRNA from mRNA, and translation makes rRNA from tRNA. These processes occur only in the cell membrane and do not involve hydrogen bonding.
