DNA Replication - ANSWERDNA helicase breaks hydrogen bonds. Each strand acts as a template. Free nucleotides attach. Complementary base pairing occurs- AT and CG. DNA polymerase joins nucleotides. Hydrogen bonds reform. Semi-conservative replication- new DNA molecule contains one old and one new strand Transcription - ANSWERDNA helicase breaks hydrogen bonds between DNA strands. One strand acts as a template. RNA nucleotides attract to exposed complementary bases on DNA. RNA polymerase joins ...

Species (Charles Darwin) - Answer-set of individuals closely resembling each other - knew than an understanding of variation within and between specials was critical for taxonomy and evolution Species (Modern Synthesis) - Answer-species are fundamentally different from the taxa about and below them in taxonomic hierarchy Species (Folk Concept) - Answer-Individual plants and animals can be mentally grouped into a number of taxa, individuals are basically alike - reproductive compatibility ...

Molecular Epidemiology (VZID) Molecular epidemiology - Use of DNA based tools in order to view the epidemiology of an infectious disease. Problems with molecular epidemiology - Very small. Identification of strains is difficult. Tracking infectious diseases and the evolution of pathogens. Qualitative - Looking for the presence/absence of pathogen. Is only useful for diagnosing a diseases. Quantitative - Data that provides information of the severity of diseases. Can identify small scal...
