BIOL 1201 : Test 3 Notes
Document Summary
Mastering biology and practice test http://www. dnai. org/index. htm: click on code then copying the code then putting it together and then select transcription . Dna replication: begins at many origins, strands must separate and unwind, helicase, topoisomerases and ssb proteins, add primer, primase, builds 5" to 3" and anti-parallel, replication, dna polymerase, build 5" to 3" and anti-parallel, fuse sections, dna ligase. Questions: what happens if the wrong base is added, where does the energy come from, why does dna polymerase inly build 5" to 3", the energy to build comes from the nucleotides themselves. They are all linked together: can errors in dna be repaired after replication, depends on the error. Central dogma figure 17. 3: flow of information within a cell, the flow is largely in one direction. Dna transcription involves making ___ from dna: protein. Transcription figure 17. 8: rna polymerase binds to the promoter site (tata box) figure. 17. 9: rna polymerase builds the new strand 5" to 3" with complementary.
