Gene is a new staff-level auditor on the audit of CalPower, a publicly traded energy and utility company. On his first day, his senior informs him that the engagement team is scheduled to have lunch with the internal auditor to discuss ways to improve this year's audit. While Gene has heard a lot about internal auditing in school and has some friends who recently began working as internal auditors, he is unfamiliar with exactly what internal auditors do and how internal and external auditors can work together to improve the audit process. Gene decides to take a look at last year's internal audit report prepared by CalPower's internal auditors. He notices that the report includes a sentence that reads, "CalPower's Internal Audit group maintains a high level of independence from management." Because Gene is intimately familiar with the extensive independence requirements of his own firm, he cannot figure out how CalPower's internal audit group can possibly assert their own independence. What is meant by independence from management for internal auditors? 250-500 words

Researchers have long been asking the question of what causes addictive behavior and why some people feel compelled to keep abusing substances they know are harmful and detrimental to themselves. Growing evidence suggests both the biologic and genetic basis of addiction, which may explain this apparently self-destructive behavi
In this Nature journal article about the dog genome, how do I answer the following questions? What was the author's purpose? Why did the author decide to sequence the domestic dog's genome?

Gregor Mendel discovered that tall was dominant and short recessive in pea plants. When he crossed two plants that were both heterozygous tall (Tt) he found a 3:1 ratio of tall to short (75% tall, 25% short) in the offspring leading him to conclude that in a monohybrid cross, the offspring would show a 3:1 ratio of dominant to
In couples where each person is heterozygous for the sickle-cell gene, there is a probability of 0.25 that any child of the couple will have the disease. A husband and wife, who are both heterozygous for the sickle-cell allele, are planning to have a family of four children. What is the probability that their first child wil
A locus in mice has been identified as determining pigment production.When parents heterozygous at this locus are mated, 3/4 of the progeny are coloured and 1/4 are albino.Another locus determines the actual coat colour; for example, when two yellow mice are mated,2/3 of the progeny are yellow and 1/3 are agouti.It was noticed t

Dihybrid crosses: Using the principles of Mendelian genetics, determine the genotypes and phenotypes of the resulting offspring from a parental dihybrid cross. The solution demonstrates how to find the phenotypic and genotypic ratios of the resulting progeny.
A scientist studying diploid pea plants is interested in two particular traits of the plant: pea color and pea texture. From previous studies, the scientist knows these traits to be genetically unlinked; therefore, these traits follow the Mendelian principles of segregation and independent assortment. The scientist also knows th
Given the complete sequence of an organismâ??s genome, 500 Mb, find motives that might regulate genes, based on the putative motivesâ?? proximity to known expressed genes.

This solution provides a map of a typical Ti-based plasmid from agrobacterium tumefaciens, explains the various elements present and why they are needed to transfect a gene into plant cells.
Early research established that the full naturally occurring Bt protoxin is a protein containing 1156 amino acids (later work has shown that insecticidal activity results from a much shorter amino acid sequence). The Bt protoxin gene was introduced into plant cells using a vector based on the Ti plasmid of Agrobacterium tume
