(VCL) Introduction / Generic Lab Introduction Virtual ChemLab is a collection of realistic simulations. There are two general chemistry laboratories‚ including quantum and inorganic. The purpose of the quantum laboratory is to allow students to explore and better understand the foundational experiments that led to the development of quantum mechanics. In general‚ the laboratory consists of an optics table where a source‚ sample‚ modifier‚ and detector combination can be placed to perform

OCA 3 The traits I chose to do my Punnett squares on are my blue eyes and my freckles. I got my blue eyes from my dad‚ and my many freckles from my mom. Both my parents have homozygous alleles for blue eyes. My dad has AA and my mom has aa. While my dad has homozygous for freckles and my mom had heterozygous. My dad has no freckles so he has aa‚ while my mom has tons of freckles so she has Aa. The capitol A’s represent the dominant traits and the lower case a’s represent the recessive traits. Since

3b. Chi squared analysis A chi-square test is also referred to X². It is a statistical test that is used to find a significant difference between the observed data to the expected data in one or more groups. To calculate a chi square you have to carry out the equation‚ X^2= ∑▒(O-E)"²" ÷E. Hₒ = this means that statistically there is no change between the observed and the expected frequencies of the results. Hₐ = this means that there is a significant change between the observed and the expected

Chi-Square Test Chi-square is a statistical test commonly used to compare observed data with data we would expect to obtain according to a specific hypothesis. For example‚ if‚ according to Mendel’s laws‚ you expected 10 of 20 offspring from a cross to be male and the actual observed number was 8 males‚ then you might want to know about the "goodness to fit" between the observed and expected. Were the deviations (differences between observed and expected) the result of chance‚ or were they due to

Chi-square requires that you use numerical values‚ not percentages or ratios. Then calculate 2 using this formula‚ as shown in Table B.1. Note that we get a value of 2.668 for 2. But what does this number mean? Here’s how to interpret the 2 value: 1. Determine degrees of freedom (df). Degrees of freedom can be calculated as the number of categories in the problem minus 1. In our example‚ there are two categories (green and yellow); therefore‚ there is I degree of freedom. 2. Determine a relative

Root mean square deviation (RMSD): The root mean square deviation (RMSD) is a measure of structural differences that are observed on superimposition of two protein structures at a different time points i.e. current position and previous position. The RMSD values for backbone atoms of each residue were calculated for entire trajectory to see the evolution of structure with time. The RMSD plot is shown in Supplementary Figure S7 where timestep is plotted on X-axis while RMSD (Å) is plotted on Y-axis
