Protein Synthesis

Where are proteins made in a cell? Proteins are made at the ribosomes Nucleus Vacuole Ribosomes Cell membrane

DNA does not leave the nucleus because its to big The mRNA delivers the code to the ribosomes Think of mRNA as Messenger DNA like a mail man DNA code mRNA Ribosomes

mRNA

mRNA brings code to ribosome mRNA leaves the nucleus and brings code to ribosome were proteins will be made

Translation In Ribosomes mRNA tells ribosomes which amino acids are needed to make protein Remember: 3 bases (letters) for one amino acid AMINO ACID tRNA mRNA In Ribosomes

Protein Synthesis A particular protein is created from sequence of amino acids Remember order of amino acids determines the type of protein which determines shape.

Proteins Building blocks of life Enzymes Hormones Neurotransmitters Antigens Antibodies Proteins also determine physical characteristics like hair color, eye color, skin color
