Students will read excerpts from Frederick Douglassâs groundbreaking autobiography, Narrative of. the Life of Frederick Douglass, an American Slave, which provides vivid firstâhand accounts of the. lives of slaves and the cruel actions of slave owners. Students will demonstrate their understanding.
Key Concepts: Bacterial DNA polymerase I enzymes are multidomain proteins with separate polymerisation, proofreading and 5â²â3â² exonuclease functions. They perform a vital function in bacteria by carrying out DNA repair and some aspects of chromosomal replication.
In bacteria, primase binds to the DNA helicase forming a complex called the primosome. Primase is activated by DNA helicase where it then synthesizes a short RNA primer approximately 11 Â±1 nucleotides long, to which new nucleotides can be added by DNA polymerase.The RNA segments are first synthesized by primase and then elongated by DNA polymerase.Then the DNA polymerase forms a protein complex with two primase subunits to form the alpha DNA Polymerase primase complex.he RNA segments are first synthesized by primase and then elongated by DNA polymerase. Then the DNA polymerase forms a protein complex with two primase subunits to form the alpha DNA Polymerase primase complex.
