Chloroplasts B. Golgi apparatus C. Lysosomes D. Mitochondria E. Nuclei 12. Give two examples of biological polymers. For each, give the name of the subunit that is assembled to form the polymer, and give the type of covalent bond that joins the subunits. Type of polymer Subunit used to make polymer Bonds joining subunits 14.
Many proteins can undergo change their shape between two alternative stable and functional forms.
More than one answer may be correct. Produces intermediates called Okazaki fragments that are later ligated together 16. Nucleosomes bind nonhistone chromosomal proteins HMG 14, HMG 17 18. You have just isolated a mutation in yeast cells in which the enzyme telomerase is active when the cells are grown at 25 o C, but is inactive when the yeast are grown at 30 C. Explain what structure or biochemical process in the yeast cells would be affected by this mutation. Synthesis of ribosomal RNA and assembly of ribosomes 24.
