Question
For the following questions, refer to Chapter 4 in the textbook. Most of these questions are in chronological order. 14. The instructions for building proteins are stored in these long biomolecules. 15. The instructions for building proteins found in this cellular structure. 16.The process of making a copy of a gene is called: 17. The end product of the process (previous question) is: 18. The making of the copy of the gene is catalyzed by this enzyme 19. The next step in the nucleus involves cutting and splicing of the copy. This step is called: 20. The sections of the copy that are spliced together are called 21. The sections that are removed from the original copy are called: 22. The second major phase in the making of a protein takes place in the cytosol. This process in this phase is called: 23. The specific 2-subunit structure involved in the process is: 24. This molecule delivers the correct amino acid for the growing peptide. 25. This level of protein structure is achieved during this 26. The bond formed between the two amino acids is named 27. This 3-nitrogenous base complementary sequence process bond. matches up with the sequence mRNA to ensure the correct amino acid is placed in the growing chain. 28. The phase after translation for some peptide involves some changes such as cleavage, cross-linkage, or folding. This phase is called: 29. Sometimes the ribosomes attach to this membranous organelle so the peptide can enter and take on higher levels of structure. 30. Peptides or proteins that are going to be secreted from the cell are packaged in vesicles in this membranous organelle.Explanation / Answer
14. mRNA contains coding information to synthesize proteins.
15. Ribosomes are involved in protein synthesis
16. Transcription synthesizes a complimentary copy of a gene sequence.
17. The end product of transcription is RNA
18. RNA polymerase mediates transcription.
19. Splicing involves removal of introns and joining of exons.
20. The sections of RNA that are spliced together are exons.
21. The sections of RNA that are removed are introns.
22. Translation
23. Ribosome
24. tRNA
25. Primary structure
26. Peptide bond
27. Anti-codon of tRNA
28. Posttranslational modifications
29. Rough endoplasmic reticulum
30. Golgi membrane
