What specific mutation is in each of the following proto-oncogenes: A)EGF receptor, B) Ras, C) Src kinase, would cause them to become oncogenes? Explain. Solution A) The most common EGFR mutations are deletion of exon 19 which converts the EGFR proto oncogene to oncogene that leads to lung cancer. B) Ras proto-oncogene encodes a protein that receives and transfers signals required for cell division. Mutation at amino acid position 12 or 61 causes formation of oncoprotein that leads to uncontrolled cell division. Thus mutation of amino acid 12 or 61 converts Ras proto-oncogene to oncogene. C) A truncating mutation of codon 531 of SRC proto-oncogene converts it into oncogene that leads to colorectal cancer.

6. List and define the underlying conditions, or assumptions, which have had an impact on the development of GAAP. Solution ANSWER: The underlying conditions/ assumptions, which have had an impact on the development of GAAP are as follows: --Business entity: The company for which the financial statements are prepared is distinct and separate from the owners. --Going concern or continuity : The assumption is made that the organisation will remain in business for an indefinite time frame. --Monetary unit : Accountants requires certain standard of measure to bring financial transactions together in an appropriate way. --Realization: Revenue must be recognized when the earning process is virtually complete and the exchange value need to be objectively determined --Matching: This concept states to recognize the costs that are related with the recognized revenue --Full disclosure: Accounting reports must disclose all facts that may influence the judgment of an informed reader --Materiality: The approach involves the relative size and importance of an item to a business. --Verifiability: The accountant need to adhere as closely as possible to verifiable data. --Industry practices: Few business use accounting reports that do not conform to the general theory that underlies accounting --Transaction approach : The accountant records only events that affect the business financial position and also can be reasonably determined in monetary terms. --Accrual basis: Expenses need to recognized when incurred (matching concept), and revenue are to be recognized when it is realized (realization concept), and --Consistency: The business must give the similar treatment to comparable transactions from period to period --Conservatism : The measurement with the least favorable effect on financial position and net income in the current period need to be selected. --Historical cost : Of the numerous values that could be used, the objective and determinable value should be selected -- Time period With this assumption, inaccuracies of accounting for entity short of its complete life span are accepted..

Using the six general trends of the general environment, give a hypothetical example of how each trend could affect a restaurant business. Solution There are six general trends of the general environment-- 1) Demographic Segment--It consists of people from different ethnic groups like Indians, Europeans, Asians etc and its affect on a business. In case of a restaurant business opening of a Indian restaurant in China will attract lower customers 2)Socio Cultural Segment--It consists of diverse set of people in the workplace who helps in the company\'s success in the Global Market. E.g. a business employing women, not engaging into racial discrimination etc. will attract more employees 3)Economic Segment--It depends on the nation\'s economic condition in the World Market. In case of a restaurant business, an economic slowdown or recession will have a negative impact on the business. 4)Legal Segment--This segment is dependent on an economy\'s governance laws, policies, taxation laws and regulations for its employees. In case of restaurant business, a restaurant set up in a country with heavy taxes and strict regulation, operations can be difficult and prove to be of losses. 5)Technological Segment--It relates to technological advancements and updation of newer technology at pace with the competitors. In case of restaurant business, restaurants adopting newer technologies will be able to produce more and earn more 6)Global Segment--This segment expands the organisation globally so that it can gain a competitive advantage over its competitors when they have a global presence in the industry. In case of a restaurant business, going global can prove to be profitable if given chances..

Pattern of Stars Listing 6.4 in the text book demonstrates the use of a nested for loop by printing a pattern of asterisks (stars), starting from the least number of stars per row (1) to the most number of stars per row (10). You will modify this program so that it does the following: Asks the user how many rows of stars they want. Prints the stars starting with the least stars per row and ending with the most stars per row, but the stars must be lined up along the right margin instead of the left. (In other words, print a version of the pattern that has been flipped horizontally i.e. along a vertical axis). You will need: An input statement to prompt the user for the number of rows. An assignment statement to store the number of rows. A nested for loop as shown in Listing 6.4 (pg 263). You will need to modify the conditions in some of your for loops to accomplish this task. This time, you will need two for loops nested within the outermost loop. The outer loop will control the number of rows, as in the example. One of the inner loops will control the number of stars per row, again as in the example. You will need to create another for loop that controls the number of spaces per row, to achieve the intended pattern. The spaces need to be printed before each row of stars is printed. Note: The two inner loops do not have to be nested. See the code shell for the intended design. Sample output: Enter the number of rows: 8 * ** *** **** ***** ****** ******* ******** Code Shell //********************************************************* // StarPattern.java // // This is a modified version of the Stars.java program // from Listing 6.4 in the text. //********************************************************* //import Scanner class here public class StarPattern1 { //------------------------------------------------------ // Prints a triangle shape using asterisk (star) // characters. //------------------------------------------------------ public static void main(String[] args) { //Create Scanner variable final int MAX_ROWS = 10; // Replace this constant // with a variable to store // the number of rows //Ask for number of rows //Store in variable for (int row = 1; /*adjust condition*/; row++) { /*insert a for loop here.

Let’s assume 3M produces “Command Hooks” at a rate of 10,000 units per day. Before reconfiguring their production process, their flowtime through the process was 100 days. After reconfiguring, the new flowtime is 35 days. After reconfiguring, how many units of work in progress inventory are in the process? < 100,000 Between 100,000 and 300,000 Between 300,000 and 600,000 Between 600,000 and 900,000 >900,000 < 100,000 Between 100,000 and 300,000 Between 300,000 and 600,000 Between 600,000 and 900,000 >900,000 Solution The number of units in the work in progress inventory would be in the range of 600,000 and 900,000. As the flowtime has decreased from 100 days to 35 days, thus there would be inventory of 65 days remaining in the process or in other words there would be wor in process remaining for 65 days. Earlier, when the flowtime was 100 days, then each day production was 10,000, hence inventory in the system would be for 65 days and related with producing 10,000 units per day, which would come in the range of 600,000-900,000..

In a mouse cell, a cytosine within the genome deaminates spontaneously and becomes a uracil. Which DNA repair system is most likely to detect and correct this defect before it can be fixed in the genome as a permanent mutation? Base-excision repair Mismatch repair Homologous recombination Reactivation Nucleotide-excision repair Base-excision repair Mismatch repair Homologous recombination Reactivation Nucleotide-excision repair Solution Base excision repair This is the DNA repair system that can detect and correct the spontaneous deamination Cytosine into Uracil. First, the enzyme, uracil DNA glycosylase abstracts the deaminated cytosine in the DNA. Then the sugar phosphate containing the missing base is cut out by the action of enzyme AP endonuclease. This space is then filled by DNA polymerase and DNA ligase. In this manner the Uracil is reconverted into original cytosine. The AP endonuclease enzyme can identify any site in the DNA helix that contains a deoxyribose sugar with a missing base..

How can we know that microorganisms comprising several groups and several species, are growing and producing their metabolites as desirable products for human How can we know that microorganisms comprising several groups and several species, are growing and producing their metabolites as desirable products for human Solution Scientist has been researching and found many metabolites which can be useful to humans. Micro-organisms are the surrounded by chemical signals. They produce small molecules which are popularly known as metabolites for their growth and development. Certain metabolites which they produce are used to stop the growth of pathogens. Many antibiotics (Erythromycin, penicillin) are also produced by these microbes to protect themselves from competitors. A wide range of chemicals are produced in the form of these metabolites. They are not only produced to kill but certain metabolites are used to act on activity of particular chemical to affect the cellular pathway e.g.: metabolite Compactin inhibits an enzyme in sterol synthesis pathway. This led to the production of whole new class of metabolites called statin. Micro-organisms can modify and produce many different combinations of chemicals and manipulate cellular pathways. There are certain microbes which can produce mixtures of analogues and not just 1 class of metabolites. Also antagonists of metabolites are not yet found so they are well known for their environment control. Thus microorganisms and their metabolites are the desirable products for humans.

Gomez runs a small pottery firm. He hires one helper at $11,500 per year, pays annual rent of $7,000 for his shop, and spends $22,500 per year on materials. He has $40,000 of his own funds invested in equipment (pottery wheels, kilns, and so forth) that could earn him $6,500 per year if alternatively invested. He has been offered $22,000 per year to work as a potter for a competitor. He estimates his entrepreneurial talents are worth $4,500 per year (input cost for organizing resources). Total annual revenue from pottery sales is $80,000. Calculate the accounting profit and the economic profit for Gomez’s pottery firm. Accounting Profit = $ Economic Profit = $ Solution Let me first tell you what it is, so that you understand better - In calculating economic profit, opportunity costs are deducted from revenues earned. Opportunity costs are the alternative returns foregone by using the chosen inputs. As a result, you can have a significant accounting profit with little to no economic profit. For example, say you invest $100,000 to start a business, and in that year you earn $120,000 in profits. Your accounting profit would be $20,000. However, say that same year you could have earned an income of $45,000 had you been employed. Therefore, you have an economic loss of $25,000 (120,000 - 100,000 - 45,000).Per AnnumHelper Salary11,500Shop Rent7000material cost22500Gomez funds40000Alternate Investment income6,500Gomez goodwill talent4500Annual Sales Revenue80000Annual Salary as potter22000Total Salary when working as Potter22000+6500 = 28,500Total CostHelper Salary11,500Shop Rent7000Material cost22500Gomez entrepreneurial talent450045,500Annual Sales Revenue80000Accounting profit80,000 -45,500 = 34,500Economic Profit=34,500 -28,500=6000.

1.Review news reports from a specific data breach. Choose a breach for which plausable news reports have identified how the attack occured and have identified the likely attacker. Complete the following reports. a. write a thrat agent profile of the likely attacker b. write an attack scenario for the data breach. c. write an attack case study about the data breack. 2.based on your answer to tha question above, develop an authentication policy for Alice, asuming she faces weak authentication threats at home. 3. Review news reports for cyber attacks. identify a cyber attack that relied on masquerade to succeed. Write an attack case study about that attack. Be sure to explain how the masquerade was supposed to work and whether or not it succeeded. Solution The Attack Surface describes all of the different points where an attacker could get into a system, and where they could get data out. The Attack Surface of an application is: You overlay this model with the different types of users - roles, privilege levels - that can access the system (whether authorized or not). Complexity increases with the number of different types of users. But it is important to focus especially on the two extremes: unauthenticated, anonymous users and highly privileged admin users (e.g. database administrators, system administrators). Group each type of attack point into buckets based on risk (external-facing or internal-facing), purpose, implementation, design and technology. You can then count the number of attack points of each type, then choose some cases for each type, and focus your review/assessment on those cases. With this approach, you don\'t need to understand every endpoint in order to understand the Attack Surface and the potential risk profile of a system. Instead, you can count the different general type of endpoints and the number of points of each type. With this you can budget what it will take to assess risk at scale, and you can tell when the risk profile of an application has significantly changed. Identifying and Mapping the Attack Surface You can start building a baseline description of the Attack Surface in a picture and notes. Spend a few hours reviewing design and architecture documents from an attacker\'s perspective. Read through the source code and identify different points of entry/exit: The total number of different attack points can easily add up into the thousands or more. To make this manageable, break the model into different types based on function, design and technology: You also need to identify the valuable data (e.g. confidential, sensitive, regulated) in the application, by interviewing developers and users of the system, and again by reviewing the source code. You can also build up a picture of the Attack Surface by scanning the application. For web apps you can use a tool like the OWASP_Zed_Attack_Proxy_Project or Arachnior Skipfish or w3af or one of the many commercial dynamic testing and vulnerability scanning tools or servi.
