Transcription & Translation Minh Nguyen Quang

The Central Dogma of molecular biology DNA RNA Protein

Transcription Makes mRNA = protein “blueprint” tRNA = transports amino acids Makes

Translation Protein synthesis ribosome

The Secret of Life! Another one! 3 for the charm?

Vocab dogma: something held true even without proof RNA Polymerase: unzips DNA double helix (transcription) Promoter: point where transcription begins polypeptide: protein codon: sequence of 3 nucleotides that specifies info for making an amino acid Anti-codon: sequence of 3 nucleotides in tRNA; bind to complementary codons in mRNA Stop-codon: sequence of 3 nucleotides in mRNA (stops translation) uracil: replaces thymine (T) in RNA
