February 25-meiosis continued Replication starts in many places and goes in both directions Transcription (makes RNA) Translation uses rna to make protein One strand of dna is used to make rna (transcription) Triplet code o Contains 3 nucleotides are used in amino acids o AUG->starts o UAA, AUG, UGA-> stop signal Blue dna seperates a little, rna polymerase comes into make rna by using the dna template (RNA translation) 4 kinds of RNA Ribosomal rna (rRNA) o Rna used to make ribosomes Messenger rna (mRNA) o Carries message to make a certain protein Transfer rna (tRNA)
