Multiple sclerosis (like many CNS disorders) is more descriptive than it is prescriptive. What do I mean by this? Explain one general class of problems that can cause the symptoms of multiple sclerosis. How does this class of problems lead to damage? Multiple sclerosis (like many CNS disorders) is more descriptive than it is prescriptive. What do I mean by this? Explain one general class of problems that can cause the symptoms of multiple sclerosis. How does this class of problems lead to damage? Multiple sclerosis (like many CNS disorders) is more descriptive than it is prescriptive. What do I mean by this? Explain one general class of problems that can cause the symptoms of multiple sclerosis. How does this class of problems lead to damage? Solution Multiple sclerosis is more illustrate and descriptive because it is an autoimmune-mediated process that cause damage to developing myelin. Host immune factors are going to attack individual neurons so that Multiple sclerosis is the demyelinating disorder in which “myelin of neurons” broken due to the various factors in the both neonatal and child brain leading severe cognitive and sensory –motor impairment due to the improper functioning of the flexion reflex. During multiple sclerosis, merely central nervous system with oligodendrocytes will be affected thereby improper myelination around the CNS neurons. Schwann cells will not get affected because these are myelin-producing cells in peripheral nervous system. A disease is pertaining to central nervous system is leading to complete paralysis of the muscle tone innervated with motor neurons during the functioning of the flexion reflex on the specific skeletal muscle result in irreversible flaccid & paralysis with no muscle tone. A peripheral nervous system problem can be irreversible as it can regenerate the activity of spastic nature of the muscle. Multiple sclerosis is an autoimmune disease in which, the myelin sheath covering the neurons present in the central nervous system is degraded. As a result, there will be decreased impulse conduction or loss of impulse conduction in that area. Depend upon the affected area, the corresponding organs may suffer from paralysis because loss of neurons communication specific regions. The symptoms of multiple sclerosis include impaired cognitive functions, bladder functions, emotional changes, depression, fatigue, sexual dysfunction, visual problems, convulsions, pain muscle spasticity, etc..

In your own words, define the following terms. Concentrate on structural make-up, location, and inter-relationships, if any. variable-number tandem repeats (VNTRs) microsatellite DNA minisatellite DNA long interspersed elements (LINEs) short interspersed elements (SINEs) telomeric repeats centromeric satellite DNA Solution Answer : a. ) VNTR\'S : The short strectch of nucleotide sequence is organized as a tandem repeat in the genome which are variable in number of tandem repeat (or VNTR) . These can be found on many chromosomes, and often show variations in length between individuals. These play a very important role in DNA fingerprinting, studying the population. b) Microsatellite DNA : These are di-, tri-, or tetra nucleotide tandem repeats in DNA sequences. where in the number of repeats is variable in populations of DNA and within the alleles of an individual. The sequence has a 20 dinucleotide repeat (40bp) stretch. These are developed by sequencing the exon portion of the gene which varies between individual to individual. These help in construction of geneitic linkage maps, function of various genes , study of genes by knocking out the function. These are co dominantly inherited in mendialian seggregation. c): Minisatellite DNA : A minisatellite is a tract of repetitive DNA in which certain DNA motifs (ranging in length from 10–60 base pairs) are typically repeated 5-50 times. Minisatellites occur at more than 1,000 locations in the human genome and they are notable for their high mutation rate and high diversity in the population.They are generally GC rich and variant repats are tandemly intermingled, which make the minisatellites ideal for studying DNA turnover mechanisms. They are also called variable number of Tandem repats because the number of repats in a given mini satellite vaies gratly among individuals. d) LINES : These are Long interspersed nucleotide sequences these are active or degenerate descendants of transposable elements. these are related to LTR transposons, but distinct in their structure e) SINES : These are nothing but Short interspersed Nucleotide sequences, these are Non- autonomous transposable elements (lacking the ability to mediate their own transposition) and their degenerate descendents. these are originally derived from tRNA sequences and distinct from retrotransposons SINEs are retrosequences that range in length from 75 to 500 bp, do not possess any reading frame,Thus their retroposition mustbe aided by other genetic elements . These elements lack LTR\'s and introns, possess an encoded poly A tail .SINEs require cross mobilisation for transposition. f)Telomere repeats : A telomere is a region of repititive nucleotide sequences at each end of the chromosome, which protect the end of the chromosome from deteriotation or from fusion with neighbouring chromosomes this sequence of TTAGGG is frequently repeated approximately 2500 times in humans. Telomeric repats are the tandem arrays of a short G rich sequen.

Heisenberg Uncertainty question... Why does my professor write deltapydeltay>h/4pi and then h (bar) = h/2pi? The book just says deltapydeltay>h/2pi. What is going on? Pic here. Small 1. Large py Large ay, Small p There is a reciprocal relationship between p and y. 2 2T Solution The uncertainity principle states that if position is known more accurately(smaller delta y) , the less accurately you know the momentum of the particle(larger delta py) and vice versa. So, delta Pydeltay>=h/4pi= h(cross)/2 where h(cross)= h/2pi..

Compare the following: bacterial species, bacterial strain, and bacterial type. Explain the relationship and development of strains and types to a species. Solution Bacterial species: It is a group of prokaryotic organisms which are ecologically distinct where many ecotypes of bacteria are grouped under a genous. These bacteria show a certain level of phenotypic identity, above 95% pair-wise average nucleotide identity (ANI) and over 97% 16S rRNA identity. bacterial strain: A strain is a low level taxonomically characterized micro-organism within a particular species that show genetic variance. Bacterial types: Bacteria can be classified based on cell wall type, and shape into different types. Based on cell wall type: gram positive, cells take up purple gram stain due to peptidoglycan rich cell wall egs (Streptococcus pneumoneae). Gram-negative bacteria such as vibrio cholerae which cause cholera take up pink stain due to thick peptidoglycan layer in their cell wall. Based on shape bacteria are classified into coccus (spherical shaped bacteria, egs.streptococcus), bacillus (rod-shaped bacteria egs. Ecoli), Vibrio (spiral or comma-shaped bacteria egs. Vibrio cholerae), spirillum (Spiral shape bacteria with more rigid structure egs: Heliobacter Pylori corkscrew shaped bacteria), Spirochete (Long thin flexible bacteria which are corkscrew shaped egs: Treponema pallidum) A species is a higher taxonomical classification which further breaks down into different strains that are genetically different. A type of bacteria shows which morphological differences and cell wall characteristics of a bacteria. The lowest level of classification would be based on type of species. A group of organisms of the different type, different morphological feature and virulence carrying out similar function would be classified under a strain. These strain would have micro-organisms, with genetic variance egs. A species of bacteria E. coli lives in the intestine and is good for human but it can also turn out to be pathogenic due to the 5% genetic variance among strains. Enteropathogenic and enterotoxigenic bacteria cause diarrhea in humans particularly children. Many such strains are grouped together under species egs E. Coli species. Which contains all the pathogenic and nonpathogenic E.Coli bacteria. These bacteria have 97% 16s rRNA identity, therefore falling under one species..

Acid rain negatively affects plants by A. reducing the photosynthetic rate in the leaves B. burning the leaves and bark. C. leaching cations that the plant needs from the soil D. leaching anions from the soil that the plant needs Solution Acid rain is a mixture of inorganic acids like H2SO4 and HNO3. These acids are from upon the reaction of pollutant like NOx and SO2 with water oxygen and other components present in the air. Both the acids are strong acid and it is the property of strong acid to dissociate into proton and Sulphate or Nitrate ions. In the soil cation, such as Potassium, calcium and magnesium are present, in their mineral forms, which are exchange with proton in acidic condition. Once cation is exchanged they leach into the soil are no more available for the plants..

A protein, called pRb (protein for retinoblastoma) is synthesized by a gene (Rb) on chromosome 13 in humans. When mutant or absent in the homozygous state in a retinal cell, there is a high likelihood of developing a cancerous condition of the eye called retinoblastoma. Nonmutant pRb binds with and temporarily inactivates E2F, a transcription factor that stimulates genes to produce proteins that initiate S phase of the mitotic cell cycle (thus, Rb is a negative regulator of cell division). When phosphorylated in response to a variety of normal stimuli, pRb normally releases E2F and cell division is stimulated. Thus, Rb is a tumor suppressor gene. (For a recent review, see H. Liu et al. (2004), \"Novel functions of the RB tumor suppressor.\" Current Opinions in Genetics and Development 14: 55–64. When retinoblastoma occurs in families, the disease tends to have an early onset and express bilaterally (both eyes). When sporadic (spontaneous, not inherited), it tends to show later onset and be unilateral (one eye only). Individuals who inherit a predisposition for the disease are Rb+/Rb– and may get retinoblastoma by having a mutation in the Rb+ allele.Assume that two heterozygous parents have children. One would expect the Rb–/Rb– genotypic combination in a zygote (one-cell stage of an individual) to be characterized as: a.lethal (inviable or lasting a relatively short time) b.completely normal c.having a very low likelihood of developing retinoblastoma d.having unilateral retinoblastoma only Solution A. the Rb-/Rb- genotype B. the Rb+/Rb- genotype C. the Rb+/Rb+ genotype So answer is A.

Liquid water is denser than ice, which is more water behaves like other substances in terms of density. At all temperatures, water vapor. liquid water, which is water vapor is denser than ice, which is more dense than liquid water. Solution Answer: Answer: 6). a). Ionic NH4Cl, or Ammonium Chloride, is a salt, which means it has an ionic bond. 7). d). nonpolar covalent bond Nonpolar covalent bonds are a type of chemicalbond where two atoms share a pair of electrons with each other. Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms. 8). c). van der Waals force If the molecule is nonpolar, then no dipole-dipole interactions or hydrogen bonding can occur and the only possible intermolecular force is the weak van der Waals force 9). a). Liquid water is more dense than ice, which is more dense than water vapor When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water.Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density. In the gas/vapor phase, molecules have very little interaction with each other and they are at large distance, whereas in liquid and solid, molecules are in continuous contact with each other. It is therefore clear that there are more molecules per liter in ice than in water vapor, and therefore the density is larger..
