Transcription Unit Structure — a labelled NEET Biology diagram with a definitions lexicon.
Transcription Unit Structure Labelled parts: Genetics, Gene Expression, Molecular Biology. A DNA sequence located upstream of a gene that provides a binding site for RNA polymerase to initiate transcription. The DNA strand with 3'-5' polarity that serves as the template for RNA synthesis. The DNA strand with 5'-3' polarity which has the same sequence as the RNA transcript (except T is replaced by U).
