CHOOSE THE BEST ANSWER What is the relationship between the terms “genotype” and “phenotype”?

CHOOSE THE BEST ANSWER The BRCA gene is a tumor-suppressor gene that regulates the cell cycle. Mutations in BRCA are associated with the development of breast cancer.  As a tumor-suppressor gene, how do you expect mutations in BRCA to disrupt the cell cycle?

CHOOSE THE BEST ANSWER Hunter Syndrome is a rare genetic disorder that is inherited as a recessive X-linked trait. The healthy allele is H, and the allele for Hunter Syndrome is h. A husband and wife have 2 sons and 2 daughters. One son and one daughter have Hunter Syndrome. What are the genotypes of the parents?

CHOOSE THE BEST ANSWER FOR EACH QUESTION You have identified the mutation in a p53 gene responsible for an aggressive type of lung cancer. The normal template sequence is on the top, while the mutant template sequence is below. The specific mutation is shown below in red. What type of mutation is it? [answer1] What change does the mutation cause? [answer2] Normal p53 DNA Sequence: 3′ – AAT GCA AAA CCA TTG CCA – 5’Mutant p53 DNA Sequence: 3′ – AAT GCA AAT CCA TTG CCA – 5′

CHOOSE THE BEST ANSWER Zlorp is an alien world is governed by Mendelian genetics, so your hard-learned “Earth Biology” will still apply. On Zlorp, there’s a vegetable called Zulara, which a lot of Zlorpians love. Unfortunately, there’s a disease that’s sweeping through the Zulara population. Zlorpians have discovered that Zulara susceptibility to the disease is controlled by a single gene with two alleles – S (susceptible) and s (not-susceptible). A Zlorpian farmer crosses a Zulara plant with susceptible fruit (Ss) with a plant with non-susceptible fruit (ss). What is the chance that any offspring of this crossing will not be susceptible?

CHOOSE THE BEST ANSWER The spinach plant (Spinacia oleracea) is a diploid organism. The total number of chromosomes in a spinach somatic cell is 12 (2n = 12). Following meiosis, how many chromosomes would you find in a spinach gamete?

CHOOSE THE BEST ANSWER The building blocks of DNA are nucleotides. The four nucleotides of DNA are commonly referred to by the first letter of its full name: A, T, C, and G. What component of the following is not a component of a nucleotide molecule?

CHOOSE THE BEST ANSWERS Which 3 of the following processes DO NOT generate new, heritable genetic variation in a population?

CHOOSE THE BEST ANSWER We reviewed multiple definitions of life, including one from the textbook. All of these definitions identified a common set of basic characteristics that must be met for something to be considered alive. Which of the following is not included in that common set of basic characteristics?

(a) (2 points) What is penetration testing? (b) (4 points) What does it mean to be “stealthy” during a penetration testing? (c) (4 points) What are the benefits of penetration testing?
