Protein Synthesis Steps

1DNA unzips in the nucleus in interphase
2mRNA nucleotides transcribe the complementary DNA message
3mRNA leaves nucleus and goes to ribosome

4mRNA attaches to ribosome and first codon is read
5tRNA with anticodon UAC brings in proper amino acid from cytoplasm
6a second tRNA brings in new amino acid
7ribosome adds amino acid to the first amino acid with a peptide bond
8ribosome slides to next codon for translation
9tRNA released into cytoplasm until needed again
10tRNA returns to ribosome, adds amino acid to growing polypeptide chain
11ribosome continues sliding along mRNA until stop codon is reached
12New Poplypeptide chain (protein) is completed
