Document Summary

Is the process of making a copy of an organism"s entire genome. What"s the point: to ensure that a complete set of genetic information is passed on to the next generation. All of the information contained in dna must be copied before a cell divides. Dna replication: helicase enzyme unwinds and unzips dna, dna polymerase enzyme assembles and proofreads new dna strands, each resulting dna molecule consists of one original strand and one new strand, semiconservative replication. The end product of dna replication: a complete copy of the genome. Is the process of making mrna from the dna of one particular gene. What"s the point: the cell can turn this message into a protein. End product of transcription: rna, codes for insulin. Is the process of de-coding the message from rna and making a protein. What"s the point: proteins are important for all biological reactions. The message in rna is used to make proteins.
