1: Measurements in the Laboratory (Experiment)

Chemistry is the study of matter. Our understanding of chemical processes thus depends on our ability to acquire accurate information about matter. Often, this information is quantitative, in the form of measurements. In this lab, you will be introduced to some common measuring devices, and learn how to use them to obtain correct measurements, each with correct precision. A metric ruler will be used to measure length in centimeters (cm).

AMINO ACID FREQUENCY

Introduction: Genetic information contained in mRNA is in the form of codons, sequences of three nucleotides, which are translated into amino acids which then combine to form proteins. At certain sites in a protein's structure, amino acid composition is not critical. Yet certain amino acids occur at such sites up to six times more often than other amino acids. In the 1960's, molecular biologists sought to determine if amino acid composition was a reflection of the genetic code or if certain amino acids were naturally selected as optimal.

Question: Are frequencies of particular amino acids simply a consequence of random permutations of the genetic code or instead a product of natural selection?

ANTIBODY BINDING
Unrestricted Use
CC BY
Rating

Introduction: Antibodies are proteins that react with foreign invaders during a humoral immune response. Antigens, small substituents of foreign invaders, elicit an immune response when they bind to the antibody. Variable regions of amino acid chains comprising the antibody create binding sites. A particular antibody has specificity to bind to one or more particular antigens.

Questions: How is antigen binding to an antibody related to antigen concentration? How can we determine binding properties of antibodies?
