Transcription RNA is made 5' --> 3' direction so DNA template strand must be in the 3' --

> 5' direction. RNA polymerase attaches to DNA template and mRNA forms a complementary

strand of DNA in the nucleus.




RNA Processing BEFORE mRNA leaves the nucleus, primary transcript is spliced and

then attaches to ribosome in the cytoplasm




Translation mRNA sequence converted to amino acid sequence; each codon = 1 amino

acid. tRNA decodes mRNA, tRNA "charged" with corresponding amino acid




Start Codon AUG; no start codon, no translation




Stop Codons UGA, UAA, UAG




Ribosome A site: tRNA is read


P site: peptide bond forms
