When a particular mutagen is identified by the Ames test and injected into mice (group A), it causes tumors, showing that the substance in carcinogenic. When cells from those tumors are injected into mice that were not exposed to the mutagen, the new mice get tumors (group B). However, when mice with tumors are mated to unexposed mice, no tumors are seen in the offsprings (group C). Explain why each of these mice get/do not get tumors and the nature of those tumors (environmental/inherited).

n yeast cells, telomerase remains active and maintains telomeres of about 300 base pairs. Propose what would happen to the telomeres over time in a yeast lineage in which the following mutations were created. The gene encoding the catalytic subunit of the telomerase is deleted.
In addition to C. elegans and Drosophila, Zebrafish are also another model organism - and have a spine. We're interested in two phenotypes, a curved spine and a gene that causes skin tumors to form on the fish's skin. We'd like to know if we could use the curved spine as an indicator if a fish may develop tumors (if the genes are linked). We'll assume that each of these traits is controlled by a single gene where: a curved spine is the result of a dominant allele S (and a normal spine is the result of recessive alleless), ⚫ and tumor growth is the result of a recessive allele t (and no tumor growths are a dominant T allele). A testcross is performed with a fish that is heterozygous for both genes and the resulting progeny are given below. TtSs x ttss curved spine & no tumors curved spine & tumors normal spine & no tumors 27 45 normal spine & tumors 30 SUN 50 Are these two genes following Mendelian inheritance patterns?

There are a small number of genes in which the maternal or paternal copy that an organism inherits is methylated. In one case in mice there are known mutations in the gene. If a mouse inherits a mutated gene from its mother, the mouse is normal. However, if the mouse inherits a mutated gene from its father, the mouse is much smaller than normal. Based on this information which allele is normally methylated, the paternal allele or the maternal allele? Explain your reasoning.
When the cloned cat Carbon Copy (CC) was born , she had black patches and white patches, but completely lacked any orange patches. The knowledgeablestudents of genetics were not surprised at this outcome.Starting with the somatic ovarian cell used as the sourceof the nucleus in the cloning process, explain how this outcomeoccurred.
Starting with a population of genetically identical mice, you discover two new independent mutant strains in which all of the animals have epileptic seizures. In both strains, you know that the epileptic seizures are due to a single recessive mutation. You cross a mutant mouse from one strain to a mutant mouse from the second strain and find that none of their many offspring undergo spontaneous seizures. From this experiment you would conclude that the two mutant strains of mice most likely have mutations in: two different genes the same gene, but not necessarily the same DNA base position the same DNA base position within a particular gene
Sarah has always lived what many consider an active and healthy lifestyle. She makes a conscious effort to eat well and exercise daily, never smoked, and drinks moderately. Many of Sarah's female relatives (including her mother and grandmother) have had breast cancer. Sarah has decided to have her genome sequenced. She is specifically interested in whether she shows mutations in BRCA1 and BRCA2 that are linked to breast cancer. What information can be drawn from the sequence data Sarah will receive? Justify your answer. • Sarah will know if she will develop breast cancer. • Sarah will know if and when she will develop breast cancer. • Sarah will know the severity of her breast cancer based on the number of mutations; that is, the more mutations in those genes, the greater the severity of the disease. • Sarah will know whether she is predisposed to breast cancer. • Sarah will know that she will not develop breast cancer if there are no mutations in those genes.
Your friend can't understand how it is possible to combine a somatic cell from their pet with an oocyte from a different animal and create a clone of their pet. Won't the animal that develops be the offspring of the two animals rather than a clone of the animal that donated the somatic cell? Explain to your friend why this is not the case.
In a mutant mouse, it was discovered that a gene "W" is moved from its original chromosomal locus to the telomere region, where chromatin is packed into heterochromatin. Given what we have learned about eukaryotic gene regulation, can you speculate how the expression of gene W in the new mouse line would be changed as compare to the normal mouse? Question 18 options: elevated in the mutant mouse than in the wild-type mouse. cannot be determined. reduced in the mutant mouse than in the wild-type mouse. no change in the mutant mouse as compared to the wild-type mouse.
