Document Summary

Dna - blueprint to make a cell. Dna >rna >protein : central dogma of molecular biology: flow of informations. Protein cannot be decoded to form nucleic acid. Never backwards ow of information from protein. Reverse transcription: still between di erent forms n nucleic acid never form protein to nucleic acid. Reverse transcriptase: uses rna as template to form dna. All virus take advantage of host machinery. Most antiviral therapies are focused on reverse transcriptase enzymes. A lot of parts of dna don"t code for proteins. They are sequences in our genome that are related to ancient viruses. They cant make functional viruses to a ect other cells anymore but they can replicate. Some codons code the same amino acids. Non overlapping: read three nucleotides at a time. Trna cannot recognize to form proteins but stop codons. Found: whenever addition or deletion of one or two bases : they lost phenotype. But addition or deletion of three: phenotype remained.
