Concept essentials
- The DNA template is read during transcription but is not consumed.
- Temporary hydrogen bonding allows copying without changing the DNA base sequence.
- The sugar-phosphate backbone preserves the continuity of the template strand.
- DNA can be reused for repeated transcription of the same gene.
