Which of the following statements regarding gene mutations is NOT true? Conditional mutations have different phenotypic effects under different conditions and can be used to study the function of essential genes. Silent mutations cannot have any phenotypic effect on an organism. Frameshift mutations often result in a truncated protein product, similar to a nonsense mutation. Dominant mutations have a phenotypic effect despite the presence of one functional wild type allele.

4. Mutations in the CX26 gene are a common cause of deafness. (You probably know some people at RIT who are deaf due to CX26 mutations.) CX26 codes for a gap junction protein expressed in the cochlea (inner ear); this protein forms a connection between cells and allows ions to pass between them Mutation 35delG is the most common cause of simple, genetic deafness in Caucasians, with a carrier rate of 1 in 35. If 1 in 5000 children in...

Inheritance and Mutations in a Single-Gene Disorder (10pts - all questions worth 0.5pts) Some diseases are caused by the environment. For example, exposure to chemicals or extremely bright lights can cause certain forms of blindness. But other forms of blindness are inherited, meaning that they are passed on from one generation to another. In this activity, you will learn about a young woman, Molly Troxel, who has an inherited form of blindness called Leber congenital amaurosis (LCA). The activity explores...

How would you explain the effects that a mistake in transcription or translation could have on an organism? A friend of mine is a "cleaning nut". She insists that when she cleans her bathroom it is sterile. Thinking about the difference between disinfecting and sterilization, what would you tell her? Hand sanitizers are found everywhere. Antibiotics are in hand soap, dish soaps and even some lotions. Why is this a bad idea? Why does it matter when considering human pathogens?...

Question 24 5 pts 1. Beta-catenin is classified as a proto-oncogene and APC is classified as a tumor suppressor gene. Both are important parts of the Wnt signaling pathway. Describe the relationship between beta-catenin and APC. Explain in detail why they are classified as a proto-oncogene or tumor suppressor gene. 2. Suppose you're working in a cancer research lab and discover a small molecule...

Experiment 1 - Coding
ab 13DNA and RNA xperiment 1: Coding In this experiment, you will model the effects of mutations on the genetic code. Some mutations cause no structural or functional change to proteins while others can have devastating affects on an organism. Materials Red Beads Yellow Beads Blue Beads Green Beads Procedure: 1. Using the red, blue, yellow and green beads, devise and lay out a three color code for each of the following letters (codon). For example...

please answer all the question to get a like. Part III Dr. Hernandez sits down with Ann and her partner. The doctor is sorry to report that Ann has breast cancer; however, because it was caught early and responds to estrogen and progesterone, the prognosis is good. At this point it looks like the cancer is stage 1. However, as Ann is young, the doctor wants to perform a couple of tests. The first test is a genetic sequencing test...

Is there GxE (gene-by-environment interaction) for the effects of sex in humans? Recall that GxE occurs where the effect of a given environmental change depends on an individual's genotype (for example, where a "better" environment is not equally better for all genotypes), or where the effect of a given genetic change depends on an individual's environment (for example, where a "taller" genotype adds a quantitatively different increment to the individual's expected height, depending on its environmental circumstances). In fact, these...

2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
