término		definición
DNA structure empezar lección		DNA is to nucleotide polymer is wrapped around each other. Covalent bonds hold the sugar phosphate backbone together. Hydrogen bonds hold the two strands together.
DNA replication empezar lección		DNA needs to be copied in interphase before cell division. Copied by semi-conservative replication. 3 main enzymes are Helicase DNA Polymerase and Ligase. DNA is synthesized by dehydration synthesis.
helicase empezar lección		unwinds and separates the DNA strands
DNA polymerase empezar lección		adds new nucleotides to each of the two strands
ligase empezar lección		closest gaps in backbone
transcription process empezar lección		initiation, RNA elongation, stop elongation
initiation empezar lección		separate DNA strands and bind RNA polymerase at promoter
RNA elongation empezar lección		by RNA polymerase. Adds bases complementary to the DNA strand it is reading
