Document Summary

An original double helixes strands will separate, complementary bases then align opposite templates, then enzymes line sugar-phosphate elements of aligned nucleotides into a continuous new strand; semiconservative. Semiconservative one strand is preserved from the parental molecule and the other is. Entire parental strand is duplicated to form a newly synthesized double stranded dna molecule. Parental dna is conserved and specific sections of each of the 2 dna molecules are newly synthesized. Provided experimental proof in 1958 that dna indeed was semiconservative. N14) and allowed to replicate, there was a hybrid density, meaning it was a mix of the two strands (ruled out conservative model), replication to produce a second generation ruled out the dispersive model. Have small circular chromosomes (e. g. , e. coli) and a much smaller genome than humans (e. g. , e. coli ~ 4 million: humans ~ 3 billion) Consists of long tracks of at base pairs since they only have two hydrogen bonds and are easier to break apart.
