6. The sequences that are removed from a mature protein.
7. The binding site for the repressor protein.
9. gene _______ gene is simply any gene that codes for a protein.
11. Occurs when a single gene gives rise to more than one mRNA sequence.(Two words with a "_" between them)
13. A classic mode of transcription control in bacteria where a repressor protein prevents a gene from being expressed. (Two words with a "_" between them.
16. _______ acting molecules are products that diffuse away from their site of synthesis to act elsewhere. (Hint: In chapter 24.1)
18. Infectious RNA molecules that function independently without encapsidation by any protein coat.
19. DNA sequences that are initially transcribed but then excised during when mRNA ages.
20. A secondary structure at the cleavage site that viroids and virusoids undergo during self-cleavage.

2. An enzyme that lowers activation energy and jump starts a chemical reaction.
3. mRNA with introns still embedded in the code.
4. The sequences that are represented in the mature protein.
5. Process which the 5' terminus generated at the end of the intron simultaneously transesterificates to become linked by a 2'-5' bond to a base within the intron.
8. _____ model was proposed by Francois Jacob and Jacques Monod in 1961.
