MIC 102 Final Exam Questions with Correct Answers What are the different types of microscopy and staining and when are they used? - Answer-Types of microscopy include: light microscopy- used primarily to get an idea of the form of the bacteria, used in combination with staining to get an idea of Gram positive and Gram negative protein. Green fluorescent is used to observe cell occurrences like binary fission and movement of proteins. Electron microscopy is very detailed at getting an idea of w...

AQA A-Level Biology. 3.2 – Cells All Answers Correct Structure of Nucleus. 1. Nuclear envelope: double membrane surrounding nucleus, outer membrane continuous with the (R)ER of the cell. 2. Nuclear pores: allow the passage of larger molecules, such as mRNA, out of the nucleus. 3. Nucleoplasm: granular, jelly-like material making up the bulk of the nucleus. 4. Chromosomes: protein-bound, linear DNA. 5. Nucleolus: small spherical region(s) in nucleoplasm. Manufactures ribosomal RN...

0 1 . 1 Describe the primary structure of all proteins 0 1 . 2 This question is about the genetic code. Define universal, non-overlapping and degenerate. [3 marks] Universal Non-overlapping 0 2 . 4 Some strains of Streptococcus bacteria are more likely to cause lung disease than other strains. Strains that do not cause lung disease are quickly destroyed by phagocytes. Phagocytes are stimulated when they bind to murein on Streptococcus bacteria. Each strain of Streptococcus bacteria ha...
