Are silenced genes associated with high or low levels of DNA methylation? Solution 1.Genes are silenced by methylation(adding methyl groups). Gene silencing is the process of turning off genes,so that it will not produce proteins through translation process. 2. Gene silencing is done by adding methyl groups to the genes. So that gene is inactive. So we conclude that silenced genes associated with high methylation. Because when gene is methylated only then silencing of gene occurs..

There are several things fundamentally wrong in this illustration. Point out two of them. Point them out, describe why they are wrong, and what they were supposed to be. You can look up anything (especially the lecture 12). size or shape of illustration do not apply (e.g. RNA primer looks like only a few bases, but that is okay, or Helicase is triangular, but that is fine, too). Solution 1: Since lagging strand is discontinuously synthesized in form of Okazaki fragments, RNA primer serve to form primer for synthesis of each of these fragments. So, RNA primer should be located adjacent to the DNA pol at lagging strand. 2: DNA pol alpha serve to form RNA/DNA primers for lagging strand synthesis. These primers are then exptended by DNA pol delta. At lagging strand, only DNA pol alpha is shown..

The poor are available to do the unpleasant jobs that no one else wants to do. The poor purchase goods, such as those of poor quality, that otherwise could not be sold Jobs are established for those people, such as social workers, who provide services to the poor. All of the above are true. Conflict theorists view poverty as functional for our society. Functionalists believe poverty could best be dealt with if the poor became politically aware and active, organizing themselves to reduce inequality through government action. Conflict theorists assume that since there is such enormous wealth in modern societies, no one in these societies should go without satisfaction of their essential needs. To resolve the poverty problem, functionalists urge elimination of the stigma and negative definitions associated with poverty.

NEED HELP ON C HOMEWORK Introduction: Programmers for a Better Tomorrow Programmers for a Better Tomorrow is an organization dedicated to helping charities, medical societies, and scholarship organizations manage various tasks so that they can focus on making the world a better place! They have asked you and your classmates to help them develop some new programs to benefit their organizations. Problem: Food Bank Management (foodbank.c) Programmers for a Better Tomorrow is now in partnership with a local Food Bank which distributes food items to people in need. People come in to a Food Bank and make their donations, and others might come in to make a request for any food item they want. A Food Bank Management Program is used to keep track of the stock the Food Bank has (i.e., the donations), keep a record of requests that come in, fulfilling requests and printing the status report which consists of the amount of stock present in the food bank and the requests that are not yet fulfilled. The program will require you to make at least one array. You may choose to make multiple one- dimensional arrays: one to serve as a Donations Table and one to serve as a Request Table. The index of the array will represent the inventory type. The value in the array will represent the amount present or needed of that type. You may, instead, choose to combine these to two arrays into a single two-dimensional array. There are 5 inventory types: Protein Dairy Grains Vegetables Fruits Your program should allow the user the following options: Enter a Donation Enter a Request Fulfill Requests Print status report Exit Option 1: Ask the user for the inventory type and amount of the donation to be made. When the donation has been added to the donations table, the program should notify the user by printing out “Donation Added”. Option 2: Ask the user for the inventory type and amount of the request to be made. When the request has been added to the requests table, the program should notify the user by printing out “Request Added”. Option 3: Check each type of inventory in the Request Table. For each item that has a value in the request table, check to see if there is inventory of the same type in the donations table. If there are no donations of that type, print “ requests cannot be fulfilled.” Replace with the correct inventory type (Dairy, Fruit, etc.). If there is some inventory in the donations table, but not enough to process all requests, print “ requests will be partially fulfilled”. Reduce both the donation and request amounts based on how much of the request was able to be fulfilled. Replace with the correct inventory type (Dairy, Fruit, etc.). If there is enough inventory to fulfill the request, print “type x> requests will be fulfilled.” Reduce the appropriate amount from the Donations Table and remove the amount from the Request Table. Replace with the correct inventory type (Dairy, Fruit, etc.). Option 4: Print both tables, indicating which is for donations a.

Our understanding of genetic inheritance and the function of DNA in producing the characteristics of the individual have been developing for more than 150 years. Consider our current state of knowledge. Link genetic characteristics to DNA structure. Explain how DNA through the process of protein synthesis is responsible for the ultimate expression of the characteristics in the organism. Describe how interference in protein synthesis can result in disruption of cellular and bodily processes? How does the significance of one class of proteins, the enzymes, relate to the importance of proper nutrition throughout life? Our understanding of genetic inheritance and the function of DNA in producing the characteristics of the individual have been developing for more than 150 years. Consider our current state of knowledge. Link genetic characteristics to DNA structure. Explain how DNA through the process of protein synthesis is responsible for the ultimate expression of the characteristics in the organism. Describe how interference in protein synthesis can result in disruption of cellular and bodily processes? How does the significance of one class of proteins, the enzymes, relate to the importance of proper nutrition throughout life? Solution 1.The gene encoding the production of protein is transcribed into the gene language required for the next stage which is RNA. The RNA is then transcribed into protein for protection or the function assigned. This is a simple illustration of how DNA can regulate expression of characteristics.There are 2 parts to this process:translation and transcription.The gene for a particular trait undergoes a process called transcription. This is a process in which the language of the body\'s make-up is transcribed from one cell language to another (DNA to RNA) which the body will recognize in order to carry out the next process. The next process is the translation of the information from RNA to the actual product, which is the protein. Specific proteins play specific roles so the body synthesizes the specific protein for the specific job at the specific time. 2.Errors in protein synthesis disrupt cellular fitness, cause disease phenotypes, and shape gene and genome evolution.errors in protein synthesis reduce organism fitness: disruption of translational fidelity with common antibiotics such as streptomycin and kanamycin kills bacteria; cells with impaired translational proofreading ability display altered morphologies and suffer severe fitness defects, as do cells with elevated rates of transcription errors in an essential gene; defects in translational fidelity and in protein folding cause disease phenotypes in mouse models.Synthesis and degradation of non-functional proteins may also be costly without being obviously harmful. Ribosomal throughput dedicated to a polypeptide that will ultimately fail to function represents an opportunity cost, particularly for fast-growing organisms.

Material Science::: Why metals can go through plastic deformation while ceramics can not? Solution Metals creep, or deform in response to stress, because they exhibit malleability and ductility. The malleability and ductility of metals is due to the fact that metallic bonding is uniform in all directions throughout the solid. One plane of atoms in a metal can slide past another without encountering great resistance and without breaking bonds. Metals are therefore immune to brittle failure within a certain limit of deformation. metals expand when exposed to heat. ceramics have very little expansion when heated to the same degree.

Mendel studied the inheritance of phenotypic characters determined by seven pairs of alleles. It is an interesting coincidence that the pea plant also has seven pairs of chromosomes. What is the probability that no two of the traits studied by Mendel were determined by genes located on the same pair of chromosomes? Solution Ans.) Mendel studied the garden pea (Pisum sativum) for two main purposes. The first reason, peas were easily available. Second was peas can be both self (self-pollinate) or be cross-pollinated. The peas self pollinate because the anthers (produce the pollen) and ovaries (ovules containing eggs) of the flower are enclosed by two petals fused to form a compartment known as keel. The peas can be cross-pollinated with any two pea plants. The anthers from one plant are removed before they have opened to shed their pollen, by the process of emasculation to prevent selfing. Then, pollens are transferred to the receptive stigma with a paintbrush or on anthers themselves. Hence, the experimenter can choose to self or to cross the pea plants. It is evident from all the analysis and research that no two of the traits studied by Mendel were determined by genes located on the same pair of chromosomes. Only inked genes are located on the same chromosome are inherited together in genetic crosses. It is also proved by the three different laws of Mendel..

Life history traits are products of natural selection What are life history traits? What defines an organisms\' life history? Define and distinguish between semelparity and iteroparity. Explain what factors may favor the evolution of each life history strategy. Solution 1.Life history characteristics are the traits that affect the life table of an organism, and can be imagined as various investments in growth, reproduction, and survivorship. The trait is the most important for any organism and the change in the trait may create the difference in the organism’s level of fitness. Evolutionary forces act on life history traits serves to limit the genetic variability and heritability of life history strategies. The list of the traits are size at birth, growth pattern, age and size at maturity time, number, size and sex ratio of the offspring, reproductive and mortality rate and length of life. 2.Mostly many factors define the life history of organism but especially the unpredictability of environment. Unpredictable environment resources, hazards and competitors may fluctuate and select organism that produce more offspring than earlier and it also leads to the plasticity where the individual can shift along with the spectrum. 3.Semelparity and iteroparity are the two reproductive strategies in living organisms. Semelparity is characterized with single reproductive cycle before death and iteroparity is characterized with multiple reproductive cycles during its life time. Examples for semelparity are salmon pacific fish, butterflies, mayflies, cicadas, some mollusks, arachinids. Examples of iteroparity are mammals ,reptiles, birds etc. 4.Life history traits and the life events combination creates the life history strategies. Body size, age of maturation, high or low survivorship, and the environment type are some of the factors that favours the evolution of life history strategies. The type of behavior taking place at the life event may define the life history strategies. The life history strategy is the age and stage specific patterns and all the stages of life make up the organisms life..

How are Ecology and Environmental Science similar to, and different from, each other? 100 words or more please Solution Ecology deals with the study of interactions between organisms and their habitat/environment or more broadly – an ecosystem. It includes earth science, nutrient cycles, food chains and webs. Environmental science also deals with biological aspect of organisms but it also encompasses, physical and chemical aspects of environment and their effects on different organisms. Therefore the similarity lies in study of organisms and environment in a broader sense. But ecology will focus on groups of organisms, specific interactions – food preferences, area occupancy, species richness, mating habits, predation, migration, adaptation to new habitats,competition strategies for survival and biodiversity. Environmental science has more detailed analysis of both abiotic and biotic factors and their interplay in environment. Examples include- effects of global warming or other major environmental changes on organisms, sustainability studies, effects of human encroachment on natural resources, urbanisation , industrialization and its effects on environment.

1. How have the Internet, intranets, and extranets affected the types and uses of data resources available to business professionals? What other database trends are also affecting data resource management in business? 2. Why is the object-oriented database model gaining acceptance for developing applications and managing the hypermedia databases on business Web sites? Solution Answer 1. The Internet, intranets, extranets and the World Wide Web have a great affect on the types and uses of data resources available to business professionals and business end users. Now the users are able to access massive amounts of data from these resources, which enable them to analyze greater amounts of information so that they are able to make better decisions affecting their or other organizations .Cloud data storage, data replication, agile data architecture are few other database trends that are also affecting data resource management in business. 2. Multimedia web-based applications have become a major application area for object technology that can be applied for the Internet and corporate Intranets and extranets . Object-oriented database models are able to handle complex types of data, such as, graphics, pictures, voice, and text, better than other structures. Also, they are relatively easy to use, and they are the key technology being used in multimedia-based applications for the Internet and corporate Intranets and extranets. They support inheritance as well, i.e. new objects can be automatically created by replicating some or all of the characteristics of one or more parent objects..
