Protein synthesis is the process where cells create proteins.


There are two steps in protein synthesis. They are transcription and translation.

During transcription, mRNA (Messenger RNA) is formed in the nucleus of the cell. After mRNA has been made, it leaves the nucleus and goes to the ribosomes in the cytoplasm, where translation occurs. (DNA never leaves the nucleus.)

During translation, mRNA attaches itself to the ribosome. Then, tRNA (Transfer RNA) reads the mRNA codons (a codon is a sequence of three nucleotides that code for a protein) and attaches amino acids accordingly. This continues until tRNA reaches a stop codon.
