ADSHE Conference June 2013. POSSIBLE CAUSES. Gaps in Knowledge. Poor teaching in previous institution. Insufficient application on previous courses. Illnesses or absences from school/college. 7: . Chemical bonding. Lecture . 7 . Topics Brown, chapter 8. Basic . bonding background . information 8.1. Types of chemical bonds. Valence electrons & Lewis structures. The ‘Octet rule’ . The bacterial chromosome is a double-stranded, circular DNA molecule associated with a small amount of protein. Eukaryotic chromosomes have linear DNA molecules associated with a large amount of protein. 6 Lectures. 2. Solids. Crystalline. Noncrystalline. Gives sharp diffraction patterns. Does not give sharp diffraction patterns. Long-range periodicity. No long-range periodicity. Has sharp melting point. 6c. Chromosome Mutations. Learning Intentions. By the end of this topic you should be able to:. (c) Chromosome structure mutations. Define ‘chromosome structure mutation’ . Name 4 chromosome structure mutations . Chromosomes. The . term chromosome was coined by W. . Waldeyer. in 1888. .. Their . structures . varies in . different organisms . like . they are circular in . bacteria. . but . linear in eukaryotic organisms, however there number remains constant for a species.. inherited. traits and their variation. . Sometime people confuse genetics with genealogy, which considers relationships but not traits. Genetics is a life sciences. The science of heredity or genetics is the study of two contradictory aspects of nature : . Prokaryotic and Eukaryotic Chromosomes Organization . Dr.Sawsan. . Sajid. . - The . term chromosome comes from the Greek words for color (. chroma. ) and body (soma). Scientists gave this name to chromosomes because they are cell structures, or bodies, that are strongly stained by some colorful dyes used in research. Dr. . Shaimaa. . Munther. . Learning Outcomes - Proteins. Define the levels of protein conformation and to indicate the role of weak interactions.. Illustrate how protein structure relates to protein function using examples..
