    Experiment 3 Liquid-Liquid Extraction Discussion The success of extracting each compound out of the solution can be seen in the IR graphs for each substance. For ethyl 4-aminobenzoate‚ the N-H‚ C=O and C-O are distinguishable in their proper wavenumber positions. The amino N-H stretch was found between 3224 cm-1 and 3423 cm-1. The C=O was found at 1681 cm-1 and the C-O was at 1280 cm-1. The IR for benzoic acid also displays its significant bonds‚ O-H and C=O. The O-H was between 2566 and

    Introduction DNA (Deoxyribose Nucleic Acid) is a nucleic acid that has many names‚ each representing the phases that it undergoes (chromosomes‚ chromatin‚ genes/alleles); it resides in the nucleus (bound by 2 *phospholipid bilayers) of almost every cell in the body (red blood cells being an exception). DNA (your genotype) is double stranded and is responsible for replicating (from 46 to 92) during Interphase‚ so that mitosis can make new cells‚ repairing and allowing for growth in the body. It is

    Chemistry Laboratory I Acid Base Review Definition In general‚ an acid is a substance that can donate a proton (H+) and a base is a substance that can accept a proton. Any proton in an organic molecule can potentially be donated. The most acidic proton in a molecule would be donated first. Any lone pair in an organic molecule can act as the proton acceptor. An acid (HA) reacts with a base (in this case H2O) to form the conjugate base of the acid (A-) and the conjugate acid of the base (H3O+). HA + H2O

    Extraction of DNA from Calf or Hog Thymus/Isolation of Yeast RNA I. Abstract Nucleic acids may be divided into two groups RNA and DNA. DNA contains almost all the genetic information while RNA serves as the bridge between the DNA and proteins. Study of both DNA and RNA initially involves proper extraction/isolation. The storehouse of eukaryotic DNA is the nucleus (and in the mitochondria)‚ so experimentally‚ DNA is extracted from tissues that have a high nuclear to cytoplasmic mass ratio‚ such
