Describe The Structure Of DNA And Explain The Roles Of Dna
BIO 113 Spring 2012 - Dr. MJ Bernot
Study Guide – Exam 2
Chapter 7- IS AT THE BOTTOM. Bernot wrote it so hopefully it is useful
• Describe the structure of DNA and discuss how it facilitates the ability of DNA to act as genetic material
• Compare and contrast prokaryotic and eukaryotic chromosomes
• Describe the process of DNA replication as a semi-conservative process. Compare and contrast the synthesis of the leading and lagging strands in DNA replication.
• Explain how the genotype of an organism determines its phenotype.
• State the central dogma of genetics and explain the roles of DNA and RNA in polypeptide (aka: protein) synthesis
• Describe the three steps of RNA transcription (initiation, …show more content…
o Static
▪ Or Statis is by chemical or physical agent inhibits microbe
▪ Instead of killing them just stops them from growing and leaves them dormant
▪ Like refrigerating
o Cidal
▪ Or cide is referring to agents that destroy or permanently inactivate a particular type of microbes
▪ Completely kills microbes
▪ Burning them
• Define microbial death rate and describe its significance in microbial control.
o Microbial death rate
▪ Permanent loss of reproductive ability under ideal environmental conditions
o They use this to evaluate how efficient antimicrobial agents are
• Describe how antimicrobial agents act against cell walls, cytoplasmic membranes, proteins, and nucleic acids.
o Attacking cell
