Cell adhesion, both cell-cell and cell-ECM, can influence whether a cell will proceed through cell division or die by apoptosis. Compare/contrast the influence on cell survival and cell division between cell-cell and cell-ECM adhesion. What signal in behavior is an integrin sending to a cell when the integrin is binding its ligand? Explain your answer. What signal in behavior is a cadherin sending to a cell when the cadherin is binding to its ligand? Explain your answer. Compare and contrast how normal cells and cancer cells interpret cell adhesion (either cell-cell and cell-ECM) to a change in cell behavior. Solution Answer B Integrins and cadherins are adhesive molecules that are also called as cell adhesion molecules or CAM. Cell matrix adhesion is brought over by integrins. Integrins are the receptors that bring about ECM adhesion. Integrins activate signal transduction pathways, once they are activated by ligand binding. These signal transduction pathways mediate cell signals for cell cycle regulations, intracellular cytoskeleton organisation and new receptor movements to the cell membranes. AnswerC Integrins and cadherins are adhesive molecules that are also called as cell adhesion molecules or CAM. Junction adherin and cell cell interactions are generally carried out by cadherins. The cadherins release a beta catenin that plays a role in cell cell adhesion and carries out cadherins mediated cell division at the plasma membrane. Their name cadherin comes from their dependency on Ca2+ ions required to function. There are different classes of cadherins. It is generally seen that that cells containing a specific cadherin subtype tend to cluster together to the exclusion of other types, both in cell culture and during development. When E cadherin is expressed there is a release signal for the epithelial cadherin, followed by the expression of N cadherin which is present for neural development. When the N cadherin is expressed E cadherin is reduced , finally when there is development of notochord and so mites, E-P and N , cadherins are expressed. Answer D In cancer cells , many of the stem cells show loosened attachment and higher motility. This is generally seen in the cases where the cancer is highly invasive or malignant, affecting more than one part of the body. The molecular adhesion fingerprint is altered in cases where the tumour calls show high mobility showing a high need to dissociate. Note- could not answer the first part due to lack of appropriate descriptive evidences. Thank you..

When Gregor Mendel was developing his ideas of inheritance of characteristics, molecular genetics was not yet discovered. Explain in your own terms, why his two most important ant laws have stood the test of time. What assumptions about them were correct? Describe a scenario in which patterns of inheritance did NOT adhere to Mendelian genetics. When Gregor Mendel was developing his ideas of inheritance of characteristics, molecular genetics was not yet discovered. Explain in your own terms, why his two most important ant laws have stood the test of time. What assumptions about them were correct? Describe a scenario in which patterns of inheritance did NOT adhere to Mendelian genetics. Solution At the time of Gregor Mendel, the molecular genetics was not yet discovered but he was a statistician by training and fortunately started his study on pea plant growing in his church lawn. By careful observation and applying statistical inference, he came up with his two laws i.e. law of segregation and law of independent assortment. Law of segregation states that the factors do not mix with each other but maintain their identity and segregates (separate from each other) at the time of meiosis when gametes form (Meiosis was not discovered at that time but people knew about gametes). The other law was law of independent assortment which stated that the factors responsible for different traits assort independent of each other into gametes giving rise to all types of genotypes in F2 generation. His careful observation and mathematical background enabled him to make robust inferences which stood the test of time. The assumptions that were correct were that every factor has two alternative forms. These forms do not mix with each other and segregate in each generation when gametes are formed. There was another law that is law of dominance which states that one form of the factor is dominant over the other due to which the effect of latter is suppressed. But because only 2 laws were asked so we will put the best laws. A scenario in which pattern of inheritence did not adhere to Mendelian genetics is linkage. As many genes are present on same chromosomes, they can not assort independent of each other resulting in linkage. The amount of recombination will depend upon the distance between two genes but in general, these genes are not assorting independently..

What are the implications of Darwin\'s ideas for the traditional view of human nature (both rationalistic and Judeo-Christian versions)? What are the implications of Darwin\'s ideas for the traditional view of human nature (both rationalistic and Judeo-Christian versions)? Solution Traditional Western views of human nature assume that all humans have the same human nature: They are conscious, rational selves who have a purpose. Some Traditional views refer to this immaterially defined self as the \"soul\". One important version of the Traditional Western view of human nature is the ancient Greek view that sees humans as uniquely rational beings with a purpose. This view contends that reason can and should rule over human desire and aggressiveness. The Judeo-Christian religious view claims that humans are made in the image of God, who has endowed them with rational self-consciousness and an ability to love. In the Christian version, the self is immaterial and distinct from the body.. The Traditional view of human nature and our ordinary thinking assume that humans have a self that endures through time. Descartes claims that the enduring self is a soul. Locke argues that memory produces the enduring self. Buddhism and Hume suggest that there is no enduring self. Some scientific views challenge the Traditional view of human nature. Darwin argued that humans evolved from earlier animal species through random variations and a natural selection that is the result of a struggle for existence. Darwin\'s view has been taken to imply that human nature has no purpose and is not unique..

What is an advantage of the hanging drop method verses simple staining? What is a disadvantage? What is an advantage of the hanging drop method verses simple staining? What is a disadvantage? Solution Advantages of Hanging drop method over simple staining: Simple staining includes staining and viewing microorganisms using basic dyes which are attracted to negatively charged microbial cytoplasm materials. However, if microbes are large and if motility is to be studied; staining becomes unnecessary. In these cases, wet mount is prepared i.e. a drop of microbes is directly put on slide and observed. Hanging drop method includes placing a drop of sample below a cover-slip which is when inverted moves through hollowed-out slide. This method is advantageous because it keeps the sample hydrated i.e doesn’t dry out. This is a rapid method and makes it easy to observe especially larger microbes for examining motility. Disadvantages:.

What are key factors to consider when selecting a flow sensor? Solution 1)Viscosity and Transparency viscosity plays an important role as a sensor will not work with liquids that are too dense 2) Flow Sensor Bodies and Hazardous Chemicals Hazardous chemicals can pose a problem to the flow sensor as the chemicals can damage sensitive parts of the device such as the fittings or O-rings. Flow Range Needed Flow range sizing is important because a single flow meter can only accurately measure typically 10:1, so a unit rated for 10 L/minute will only measure as low as 1 L/minute accurately Some other options and considerations may be.

The process of DNA replication creates a particular problem for replicating the ends of linear chromosomes. 1. Describe why the DNA replication machinery has difficulty replicating DNA ends. 2. Telomerase has been identified as an enzyme that can reverse the outcome of end replication. Describe the near-universal mammalian chromosome telomere sequence and how telomerase solves the problem of end replication. Solution Answer: 1. Describe why DNA replication machinery has difficulty replicating DNA ends: Eukaryotic chromosomes are linear and not circular like bacterial chromosomes. The end of eukaryotic chromosomes contains repetitive sequences (telomere) and cannot be fully copied during each round of replication. DNA replication begins by unwinding of DNA double helix and the synthesis of new strand by DNA polymerase. Since DNA polymerase can only work in a unidirectional way (5’ to 3’) therefore one of the two new strands of DNA is synthesized continuously (leading strand) and the other strand is synthesized in small stretches called as Okazaki fragments (lagging strand). At the end of the lagging strand, since it is not possible to attach an RNA primer, thererfore, the terminal region of chromosomes does not get covered by Okazaki fragments. As a result, with each round of replication, the terminal chromosome sequence cannot be copied leaving single stranded overhangs and gradual shortening of chromosomes. This is called as “end replication problem”. 2. Describe Near Universal mammalian chromosome telomere sequence and how telomerase solves the problem of end replication: The termini of eukaryotic chromosome have specialized DNA caps called telomere which comprise of short repetitive DNA sequence. Each time a cell divides some portion of the telomere is lost. Mammalian Telomere contains hundreds or thousands of tandem repeats of the same short DNA sequence 5’-TTAGGG-3’. With each cell division telomeric sequence are lost thereby protecting the critical chromosomal regions that contains gene.Telomerase (telomere terminal transferase) is an RNA dependent DNA polymerase made up of RNA subunits and protein and is involved in elongating the length of chromosome by extending the telomeres. Telomerase enzyme binds to a special RNA molecule that contains a sequence complementary to the telomeric repeat. By using the complementary RNA as a template, it extends the overhanging strand of the telomere DNA. Since DNA polymerase cannot replicate the DNA sequence at the end of the chromosomes therefore telomerase enzyme aids in terminal replication process by attaching to the end of the chromosome. Absence of telomerase activity would result in progressive shortening of chromosome with each cell division..
