Protein synthesis worksheet 1. In bacteria (prokaryotes), as the cell is translating a protein it can also be ___________. 2. Protein synthesis makes a polypeptide out of these monomers? 3. Nucleosides are nucleotides that have three ____________ instead of one, the energy is used to drive the synthesis reactions. 4. List the types of RNA’s used in protein synthesis and their role. 5. __________ are cut out of the pre-mRNA sequence. 6. These are added onto the ends of the Pre-mRNA sequence. 7. To make secretory proteins, this type of RNA brings the ribosome to the ER. 8. The stop codon codes for this… 9. ______________________________ results in more combination of the different domains of a gene in the code getting expressed. 10. The poly A tail determines how many times the RNA transcript can be _________________. 11. RNA polymerase attaches to the _____________ a section of DNA before the transcribed unit. 12. To open the DNA strand during initiation, ___________ bonds are broken on a stretch of A’s and T’s called the ____________ box 13. Transcription __________ are added to the transcription initiator complex 14. To elongate the strand _________ (DNA / RNA ) nucleosides are added. 15. RNA processing happens in the _________________ (nucleus /cytoplasm). 16. Spliceosomes cut out the _______________ from the pre-MRNA transcript. 17. In bacteria there is no a. RNA processing b. g cap c. poly A tail d. all of the above 18. tRNA’s have an ____________ that is complementary to the mRNA codon 19. tRNA’s each can hold a different _______________, that gets refilled at the aminoacyl-tRNA synthetase enzyme. 20. The growing poly peptide is at the _____ (E / P / A ) site. 21. SRP’s bring the primary transcript and the ribosome to ER ( that’s rough!). 22. The mutation that has the biggest effect on the protein is the __________ (frameshift / silent/ substitution) mutation. 23. Missense mutations makes a _____________ ( different amino acid/ stop codon). 24. Nonsense mutations makes a _____________ ( different amino acid/ stop codon). 25. A chemical that causes mutations is called a ________________ .
