BIOS 280 Exam 1with Complete Solutions 100% Pass
gram stain Correct Ans-most universal differential staining technique for bacteria and it
differentiates bacteria based on their cell wall structure.
positive staining Correct Ans-any staining technique in which the dye actually sticks to the
specimen and gives it color, instead of staining the background.
subculture Correct Ans-a second generation culture made from a well-established colony
of microorganisms.
polypeptide Correct Ans-usually has more than 20 amino acids
protein Correct Ans-usually contains more than 50 amino acids
peptide Correct Ans-composed of a short chain of amino acids
greatest to lowest mass Correct Ans-nucleus
