Remote Learning Weeks 1-3 recap:
To help you focus on essential knowledge for the AP exam- I cross referenced the remaining essential knowledge elements with assigned readings, labs and lessons highlighted in magenta.
ESSENTIAL KNOWLEDGE - From course framework
Chapter 17- Campbell
IST-1.O.5 Genetic information in retroviruses is a special case and has an alternate flow of information: from RNA to DNA, made possible by reverse transcriptase, an enzyme that copies the viral RNA genome into DNA. This DNA integrates into the host genome and becomes transcribed and translated for the assembly of new viral progeny.
Chapter 15- Campbell
IST-2.B Explain how the location of regulatory sequences relates to their function.
Chapter 15- Campbell
IST-2.B.1 Both prokaryotes and eukaryotes have groups of genes that are coordinately regulated--
a. In prokaryotes, groups of genes called operons are transcribed in a single mRNA molecule. The lac operon is an example of an inducible system.
b. In eukaryotes, groups of genes may be influenced by the same transcription factors to coordinately regulate expression.
ENDURING UNDERSTANDING
IST-1 Heritable information provides for continuity of life.
LEARNING OBJECTIVE IST-1.P Explain the use of genetic engineering techniques in analyzing or manipulating DNA.
ESSENTIAL KNOWLEDGE IST-1.P.1 Genetic engineering techniques can be used to analyze and manipulate DNA and RNA--
a. Electrophoresis separates molecules according to size and charge. AP Biology Investigation # 9/Cliffs page 290
b. During polymerase chain reaction (PCR), DNA fragments are amplified.(See Cliffs page 142)
c. Bacterial transformation introduces DNA into bacterial cells. AP Biology Investigation #8/Cliffs Page 288
d. DNA sequencing determines the order of nucleotides in a DNA molecule. Campbell Chapter 18
X EXCLUSION STATEMENT—The details of these processes are beyond the scope of this course. The focus should be on the conceptual understanding of the application of these techniques.
ILLUSTRATIVE EXAMPLES:
- Amplified DNA fragments can be used to identify organisms and perform phylogenetic analyses.
- Analysis of DNA can be used for forensic identification.
- Genetically modified organisms include transgenic animals.
- Gene cloning allows propagation of DNA fragments.
