Process of Protein Synthesis

transcription

DNA to mRNA -happens in the nucleus

first step

DNA's message is copied into a messenger RNA transcript

fifth step

amino acid chain (polypeptide) can then travel out of the ER in a vesicle made by the smooth ER

translation

mRNA to protein -happens in ribosomes

fourth step

ribosome will direct amino acids to join together based on the mRNA's code (makes proteins)

1. DNA to RNA 2. mRNA leaves nucleus and goes to rough ER 3. mRNA attaches to ribosome 4. ribosome assembles amino acids 5. polypeptide chain travels out of ER as a vesicle 6. vesicle goes to golgi for final touches

steps of protein synthesis

third step

the mRNA attaches to a ribosomes

second step

the mRNA leaves the nucleus through a nuclear pore and travels through the rough ER

sixth step

vesicle will go to the golgi complex for further processing, repackaging, and labeling

nucleus ribosome endoplasmic reticulum vesicle and golgi
