Confusing DNA Replication with Transcription
Students treat DNA replication and transcription as the same copying process and mix up the product made.
Quick check
Why students make it
Both processes use a DNA template and base-pairing rules, so they feel like the same step. The misleading shortcut is thinking that any DNA template always gets copied into more DNA.
The rule done right
DNA replication copies the whole DNA molecule into DNA before cell division. Transcription copies one gene into RNA, so the product is mRNA and it uses U instead of T.
