5. Purpose of DNA Transcription
mRNA Transcript
To make messenger RNA (mRNA) from a DNA template

6. Where Does Transcription Occur?
DNA transcription occurs in the nucleus

7. Parts of the Transcription Machinery

8. Difference between DNA Replication and DNA Transcription
DNA replication copies the whole DNA strand
Creates two identical copies
Uses thymine (T)
DNA transcription copies small sections (genes)
Creates one single strand (mRNA)
Uses uracil (U)
