<span>1. Replication by means of complementary base-pairing. (This is mentioned in the W&C paper).
I think that's about it. Since you have to come up with two more, try these:
2. Transcription to RNA, also by means of complementary base-pairing
3. Not getting into a tangled mess. The double-stranded nature meant
