Document Summary
Cag forms loop and second replication will have extra copy of cag (miscalculate # copies made: changes in meiosis crossovers may effect # of repeats. Bimm 100: 2: child has 2 chromosomes (1 mother, 1 father); each chromosome has different # repeats (different primers) Integrase enzyme from virus inject dsdna from virus into human genome. Winter 2019: reverse, virus dna transcribed into mrna to encode reverse transcriptase, integrase, and other. Mobile elements : dna transposon, retrotransposon, 44% of human genome, mostly non-functional elements, 2 types of mobile elements, dna transposon cut and paste, retrotransposon copy and paste. General mechanism: copy and paste mechanism vs cut and paste original rna donor exists (increase dna. In replication fork, the transposon is already copied in both strands: the transposon jumps from strand to un- replicated region, transposon is copied again going through replication.
