BIOL 1201 : Final
Document Summary
Methylation: adds methyl to the dna bases to reduce transcription. Acetylation: acetyl is added to the histones to spread out the dna to increase transcription. Translation: cytoplasm: in humans, most cells have the same dna content. Virus: lacking the structures and metabolic machinery found in a cell, a virus is an infectious particle consisting of little more than genes packaged in a protein coat. If the genetic material is in the form of rna, it goes to ribosomes: protein starts killing dna and rna that would compete with it, the proteins start making viral shells, at the same time, rna is replicating. Hiv: hiv is a retrovirus, retrovirus codes from rna to dna, single strand rna, that dna incorporates itself to the host cell"s dna, they become part of the organism via dna. Lytic growth: a phage replicative cycle that culminates in death of the host cell is known as the lytic cycle.
