PROTEIN SYNTHESIS

 

Protein Synthesis is the process of "making proteins"  or replicating the proteins that code for the genes.  This is a multi-step process that occurs during the "S" Phase of the Cell Cycle.

 

The first Step in the process begins with the action of DNA as it "unzips" revealing its bases.

mRNA then enters the nucleus to transcribe or copy the bases.

mRNA leaves the nucleus and moves out into the cytoplasm where it attaches itself to a Ribosome.

tRNA "reads the code in groups of three; this is called a "codon". provided by mRNA and finds the amino acid that is being called for in the codon.

The amino acid is moved into the ribosome where it will begin to form a long chain of amino acid
