Protein Synthesis

Transcription 
Transcription is When DNA is changed into RNA.
Step 1
DNA unwinds
Step 2
One side of DNA "codes for a protein"
mRNA is "transcribed" from DNA by complementary base pairing (mRNA has no thymine, which is replaced by uracil)
Step 3
mRNA passes out of the cytoplasm to the ribosome

Translation
​Step 1 of Translation mRNA attaches to the ribosome.
Step 2 of Translation

tRNA's attach to free amino acids in the cytoplasmic "pool" of amino acids.
Step 3 of Translation

Protein chain continues to grow as each tRNA brings in its amino acid and adds it to the chain.
 
Translation is when RNA is being changed into a Protein.
Trna is the bringing  of the Amino Acids into the Ribosome.
Mrna Molecules carry the message from DNA to the ribosome for protein synthesis.
Rrna decodes the codon.
