Question 1 1 / 1 pts Which of the following are true regarding cancer cells and their ability to grow? Correct! The telomeres are rebuilt by the enzyme telomerase The telomeres are broken down by the enzyme telomerase The telomere inhibits cyclin and causes cell to grow out of control The telomeres are broken down and the cell grows out of control The telomeres are rebuilt and the cell undergoes apoptosis Question 2 1 / 1 pts Which of the following is an example of a malignant tumor? Pancreatic carcinoma in the pancreas Sarcoma in the muscle organ Basal cell carcinoma (skin cancer) remaining in the top skin layer Astrocytoma (neuroglia cancer) in the brain Correct! Melanoma (melanocyte cancer) in the kidneys Question 3 1 / 1 pts How is it that family members can share a predisposition to cancer? Autosomal dominant proto­oncogenes can be passed on from parent to child through the somatic cells Correct! Autosomal recessive tumor supressor genes can be passed on from parent to child through the gametes Mutations during mitosis can generate new alleles that are cancerous Mutations in somatic cells can be passed on through the gametes https://uvu.instructure.com/courses/302339/quizzes/425999 1/4 9/10/2014 Lecture 13 Quiz: BIOL-1010-151-V32-Bradshaw-SPRING 2014-XLIST Proto­oncogenes and tumor supressor genes cancel each other out until one mutates in the somatic cells and is passed on Question 4 1 / 1 pts Which of the following is a type of general cancer of the organs? Sarcoma Melanoma Correct! Carcinoma Astrocytoma Leukemia Question 5 1 / 1 pts Which of the following procedures is used to induce apoptosis in cancer cells by only damaging their DNA? Hormone Therapy Stem cell replacement Chemotherapy drugs Surgery Correct! Radiation Therapy Question 6 1 / 1 pts Moles and freckles come from melanocytes that produce melanin in the skin. Sometimes moles can be an early warning sign for a type of cancer called __________________. sarcoma basal cell carcinoma leukemia astrocytoma Correct! melanoma Question 7 https://uvu.instructure.com/courses/302339/quizzes/425999 1 / 1 pts 2/4 9/10/2014 Lecture 13 Quiz: BIOL-1010-151-V32-Bradshaw-SPRING 2014-XLIST An oncologist looks at a group of cells under a microscope trying to find cells that may have become cancerous. Which of the following would be a clear indication that some cells in the mass have become cancerous? Have contact inhibition Can induce apoptosis Have controlled growth Normal chromosomes Correct! Cells are non­specialized Question 8 1 / 1 pts No matter what type of cancer a person has, when it is known to have metastasized doctors will usually treat the person immediately with angiostatins and endostatins. Why is this done even if they don't know what caused the cancer? To raise the heart rate in preparation for chemotherapy Correct! To slow down new capillary formation and stop nutrient flow to cancer cells To boost the immune system and help fight off the cancer To try to kill as many cancer cells before actually knowing what type it is To slow down the rate of mutation in the cancer cells Question 9 1 / 1 pts Which of the following is not a role of apoptosis? keep the number of somatic cells in check in a multicellular organism remove damaged cells shaping of tissues during development Correct! increase cell cycle divisions programmed cell death Question 10 1 / 1 pts Which of the following is an example of a proto­oncogene? a gene that inhibits the cell cycle and prevents apoptosis a gene that transposes other segments of DNA into other genes a gene that inhibits the cell cycle and stimulates apoptosis https://uvu.instructure.com/courses/302339/quizzes/425999 3/4 9/10/2014 Lecture 13 Quiz: BIOL-1010-151-V32-Bradshaw-SPRING 2014-XLIST a gene that promotes the cell cycle and stimulates apoptosis Correct! a gene that promotes the cell cycle and prevents apoptosis Quiz Score: 10 out of 10 https://uvu.instructure.com/courses/302339/quizzes/425999 4/4 ...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
