Document Summary
2: coli promoters, promoter consensus (most common or average) sequences: sigma factor bonds to the. First rna processed is called the primary rna transcript: generally unprocessed, but can have cap, not spliced (has intron: 4. Mature rna: has cap (m7g), introns removed: 6. Types of rna: mrna: messenger rnas, code for proteins rrna: ribosomal rnas, form the basic structure of the ribosome and catalyze protein synthesis trna: transfer rnas, central to protein synthesis as adaptors between mrna and amino acids.

Eukaryotic rna polymerases require proteins to help position them at the promoter, called: transcription factors: 2. These factors fulfill a similar role to the sigma subunit of the bacterial rna polymerases: 3. Eukaryotic rna polymerases need to deal with chromosomal structures. Gene structure: procaryotic mrna: translation codes in sections (coding/noncoding sections)
