Chromatography Experiment of the Drosophila Eye Pigmentation Pathway Introduction: How can the use of chromatography help explain single gene mutations of the drosophila melanogaster bio-synthetic pigment pathway? This experiment was meant to help connect the mode of inheritance with different eye color mutations and pinpoint where they occur in the pigment pathway. The drosophila eye color is a result of two bio-synthetic eye color pathways‚ this is expressed as a trait or phenotype‚ a multigene

Activity in Plants Using Different Wavelengths of Light using Chromatography and a Spectrophotometer In this experiment‚ the separation of particular pigments‚ contained within a fresh spinach leaf‚ were examined. Paper chromatography is the process of separating certain molecules‚ or pigment molecules‚ based upon their polarity. Four different pigments were examined from the spinach leaf: chlorophyll a‚ chlorophyll b‚ xanthophyll‚ and carotene. Based upon looking at the pigments individual molecule

Problem How can you tell pigment separation by using Chromatography? Objective To prepare a chromatogram‚ separate pigments in a leaf and interpret the chromatogram. Hypothesis If I am to put a chromatography paper into a solvent‚ then it would separate the pigments depending on their Rf value. I think the pigments will separate in this order: Chlorophyll A‚ Chlorophyll B‚ Carotene‚ and Xanthophyll. Introduction Chlorophyll is the molecule that absorbs sunlight and uses its energy
