Genetics Braun

2. Infectious RNA molecules that function independently without encapsidation by any protein coat.
4. mRNA with introns still embedded in the code.
5. The sequences that are represented in the mature protein.
6. An enzyme that lowers activation energy and jump starts a chemical reaction.
7. 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.
10. the RNA sequence is read from _____ to ____ end don't forget the "'".
11. DNA to RNA to polypeptide. (Two words with a "_" between them)
13. Acts as a binding site for repressor proteins and when a repressor binds here, prevents transcription.
15. A product of a gene that diffuses away to act on an area different from synthesis.
18. A secondary structure at the cleavage site that viroids and virusoids undergo during self-cleavage.
19. The sequences that are removed from a mature protein.
20. ________ RNA that contains a sequence that is complementary to the correctly edited mRNA.

1. A classic mode of transcription control in bacteria where a repressor protein prevents a gene from being expressed. (Two words with a "_" between them.
3. This type of gene is any gene that codes for a protein or RNA product.
4. An alternative form of control where the gene is turned off.
8. DNA sequences that are initially transcribed but then excised during when mRNA ages.
9. This type of bond makes up the sugar-phosphate backbone of DNA. It is also involved in branching during mRNA.
12. The bread and butter of genetics. DNA-->mRNA--->Polypeptide (Two words with a "_" between them)
14. Group I and group II introns can participate in ___-____ where they can excise themselves. (hyphen)
16. Occurs when a single gene gives rise to more than one mRNA sequence.(Two words with a "_" between them)
17. Created in 1961 by Jaques Monod and Francois Jacob as a way to explain how transcription is controlled in bacteria.
