Question

which nuclear process is represented by the following steps:

1. a dna molecule untwists
2. the two strands of dna separate
3. molecular bases pair up
4. 2 identical dna molecules are produced

options: transcription, translation, recombination, replication

Explanation:

The steps describe DNA untwisting, strand separation, base pairing, and producing identical DNA molecules, which are key steps of DNA replication. Transcription makes RNA from DNA, translation synthesizes proteins, and recombination involves DNA rearrangement. So the process is replication.

Answer:

Replication (the last option, labeled "Replication")
