Protein Synthesis Steps
DNA unzips in the nucleus in interphase
mRNA nucleotides transcribe the complementary DNA message
mRNA leaves nucleus and goes to ribosome
mRNA attaches to ribosome and first codon is read
tRNA with anticodon UAC brings in proper amino acid from cytoplasm
a second tRNA brings in new amino acid
ribosome adds amino acid to the first amino acid with a peptide bond
ribosome slides to next codon for translation
tRNA released into cytoplasm until needed again
tRNA returns to ribosome, adds amino acid to growing polypeptide chain
ribosome continues sliding along mRNA until stop codon is reached
New Poplypeptide chain (protein) is completed
