Firefly luciferase is a commonly used reporter gene. The gene originates from fireflies (a type of beetle) and when it combines with its substrate, luciferin, light is produced. Luciferin is very expensive to purchase. You would therefore like to figure out the biosynthetic pathway for making luciferin so that you can get bacteria to make luciferin. This will enable you pay off all your college loans! You have obtained 5 mutant firefly stocks that each fail to glow at night. The flies in each stock have the wild type luciferase gene but ultimately fail to make the luciferin substrate. Each stock has a unique mutation in one of the genes required to make luciferin. You know that the biosynthesis of luciferin involves 5 intermediate compounds: A, B, C, D, and E. However, you do not know the order that these compounds appear in the pathway. When you feed these intermediate compounds to the mutant fireflies, they sometimes are able glow (+) and sometimes still cannot glow (-). However, when you feed the mutant fireflies luciferin, they always glow. Based on the results in the table above, write the biosynthetic pathway for luciferin, showing the order of the intermediates (A-E) and the genes (M1-M5) required to convert each intermediate to the next in the pathway. Solution This is a probem, where in you can get the answer by the means of trial and error. Now that we have all pieces to this puzzle, lets join them. E>B>D>C>A this is the pathway in the production of Luciferase..

Explain the “life” of a secreted protein molecule - trace the pathway in a cell by which a secreted protein, such as an antibody, would be produced in an animal cell, starting in the nucleus. Solution Cells secrete proteins for their own cytosol or for release into surrounding extracellular fluid. These secretions may include various hormones, digestive enzymes, antibodies, mucus etc. The transcription process (conversion of DNA to mRNA) occurs inside the nucleus. This newly formed mRNA is translated into proteins in the cytosol at cellular structures called ribosomes.the ribosome remains in the cytosol if the protein has to be used within the cell, whereas if it is destined for secretion outside the cell, the signal sequence (first few amino acids) is synthesized on the ribosome and then the ribosome docks at the rough endoplasmic reticulum (RER) for completion of protein synthesis. Proteins enter and cross endoplasmic recticulum (ER) membrane co-translationally (i.e., they cross ER during synthesis of polypeptide). In the lumen of ER, proteins undergo glycosylation and molecular chaperones aid in the process of protein folding. Misfolded proteins are retrotranslocated to the cytosol, where they are degraded by a proteasome action. The vesicles with correctly folded proteins then enter the golgi appratus where further posttranslational modifications occur including cleavage and functionalization. When the protein moves through the entire Golgi apparatus, it buds off as secretion vesicles. Now, with the help of cell\'s cytoskeleton, it moves towards the edge of the cell and attaches itself to the membrane. Eventually, vesicle fuses with the cell membrane releasing its contents out of the cell through the process of exocytosis. This secretion pathway is followed for all protein molecules including antibodies..

7. Using to Table 1 to assist you, explain the rational for the diversity of the mycobiome, as compared to the number of bacterial species identified in the lungs of CF patients. This should be a full paragraph, not one or two sentences. Solution From the tabulated data given, it can be clearly noticed that majority of the population suffers from ascomycete infections. Particularly, the most infectious species can be identified as Candida albicans followed by C. dubliniensis. Saccharomyces cerevisiae infections are also very high followed by C. parapsilosis and C. glabrata. Other types of infections are also evident in patients but these organisms remain the most frequent infective agents for patients with cystic fibrosis. Since all of these microbes spread the disease from one organism to another, they are highly communicable in nature. Also, since very high frequency of some of the species can be noticed from the data, it is also suggested that the infections are opportunistic in nature i.e. they will infect the individual as soon as his immunity against these microbes is minimized. Importantly, since a huge population is suffering form nearly similar kind of infections, it can be suggested that fixation of these microbial infections is possible in this population which can be clinically deleterious in advanced stages because eradication of these microbes using multiple antibiotic treatment would be difficult. Hence, it can be evaluated from the data that the statisitical figures are clinically alarming and demand immediate attention..

Do people from different cultures experience emotions differently? One study designed to examine this question collected data from 411 college students from five different cultures. The participants were asked to record, on a 1 (never) to 7 (always) scale, how much of the time they typically felt eight specific emotions. These were averaged to produce the global emotion score for each participant. Here is a summary of this measure: Note that the convention of giving the standard deviations in parentheses after the means saves a great deal of space in a table such as this. (a) The ANOVA F statistic was reported as 5.57. Give the degrees of freedom and either an approximate (from Table E) or an exact (from software) P- value. Sketch a picture of the F distribution that illustrates the P-value. (Round your P-value to four decimal places.) What do you conclude? We have strong evidence at the 5% level that the means are not all the same. We have no evidence at the 5% level that the means are different. (b) Without doing any additional formal analysis, describe the pattern in the means that appears to be responsible for your conclusion in part (a). Are there pairs of means that are quite similar? European Americans have the highest emotion scores, Indians are in the middle, and the other three cultures are lowest. Hispanic Americans have the highest emotion scores, Japanese are in the middle, and the other three cultures are lowest. Japanese have the highest emotion scores, Hispanic Americans are in the middle, and the other three cultures are lowest.

What type of gametes did Sutton predict? Mendel? (parental, recombinant, both) Solution 1. According to Mendel’s law of segregation : 2 . The Chromosomal Theory of Inheritance (Theodor Boveri and Walter Sutton --1903) was consistent with Mendel\'s laws and the basic postulates were: -----------------------These lead to the conclusion that both Sutton and Mendel predicted parental types of gametes because in case of parental type , gametes are produced in equal proportion but recombinant type produces gametes in unequal proportions. Besides this , In 1911, after observing that linked traits could on occasion be inherited separately, Thomas Hunt Morgan suggested that \"crossovers\" can occur between linked genes and crossover is the prime reason for recombination.

With reference to Barth (2014), discuss how the author assessed the extent to which unmodified historical cost, modified historical cost, and fair value measurement possess the qualitative characteristics specified in the IFRS Conceptual Framework. Solution The conceptual framework in IFRS states the qualitative characteristics of the financial statements to be useful which are as follows: 1. Fundamental : Fundamental qualitative characteristics are relevance and faithful representation. 2. Enhancing: Enhancing qualitative characteristics are comparability, completeness, verifiablity and understandability. According to Barth(2014), Historical cost does not possess the qualitative characteristics of the IFRS conceptual framework as it does not facilitates comparability and relevance but yes it is sometimes relevant. The historical cost should be modified to use in financial statements, it should be indexed for Inflation. Modified historical cost possess the qualitative characteristics of the IFRS. It is understandable, complete, accurate, but not considered as faithful representation. This is widely used but both modified historical cost and unmodified historical cost lack meaning. Whereas the Fair value presentation is more consistent with the new framework and hence it should be widely used. This paper concludes that assets and liabilities at large should be measured at fair value to provide the financial statements with the qualitative characteristics..

Phase contrast 4. Scanning (SEM) 5. Transmission (TEM) Solution The characteristics of each microscope is as follows: 1.COMPOUND MICROSCOPE In compound microscope the objective lens forms a real, inverted and magnified image of the object. The eye piece acts like a magnifying glass and forms a virtual erect and magnified image. Object is placed outside the principal focus of the objective lens. It consists of two convex lens, ocular, close to the eye and s3cond objective lens. It also reduces chromatic abberrations. 2. STEREO (DISSECTING) It is an optical microscope which is designed for low magnification, it uses light reflected from the surfacevof an object rather than transmitted through it. It forms three dimensional erect image as the prism under the eye piece reverses the image. 3. PHASE CONTRAST It is used to examine biological tissues (live microorganisms). It is a type of light microscopy that increases contrasts of transparent and colourless objects. This is achieved by influencing the optical path of the light. Thus contrast of light and dark makes the specimen visible to the human eye. 4. SCANNING (SEM). It is used for producing high resolution images of a sample surface. The images have 3-D appearance and best used to judge the surface structure of the sample. It produces image using focused beam of electrons. In SEM, the picture is shown on the monitor. 5.TRANSMISSION (TEM). It is based on transmitted electrons. It provides details of internal composition (show morphology, crystallisation, stress or even magnetic domains of the sample). In TEM, picture is shown on fluorescent screens. It provides 2-D picture of the sample. It uses electromagnetic lenses to focus the electrons into very thin beams..
