Teleomeres are absent in prokaryotes because
a) prokaryotes are single celled and cannot age.
b) the circular chromosome in prokaryotes has no end.
c) plasmids have the same function in prokaryotes.
d) prokaryotes lack telemerase.
Homework Answers
Option b is correct. Teleomeres are absent in prokaryotes because the circular chromosome in prokaryotes has no end. Telomeres are found in eukaryotes as they have linear DNA which tends to deteriorate every division. Thus, the function of telomere is to prevent the shortening of the chromosome ends and their from fusion with neighboring chromosomes.

Question 6 Amoeba, a single celled protist, has a specialized structure called a contractile vacuole whose function is to collect excess water from the cell and discharge this water into the environment. From this information you can deduce that Amoeba lives in an environment that is (hypertonic, isotonic, hypotonic) to the cytoplasm of Amoeba. Thus, you would expect to find Amoeba living in: A. a freshwater pond B. the ocean C. Great Salt Lake D. a bottle of unpasteurized milk...
