Transcription and Translation. Protein Structure. Made up of amino acids Polypeptide - string of amino acids bonded together (peptide bonds) Enzymes are proteins 20 amino acids are arranged in different orders to make a variety of proteins Assembled on a ribosome.
Transcription and Translation
Bases: C,G A,T
**Each group of 3 bases of mRNA (see colors above) are called a codons
Now we have mRNA transcribed from the cell’s DNA.
It leaves the nucleus through a nuclear pore into the cytoplasm
Once in the cytoplasm, it finds a ribosome where translation can begin.
The mRNA code has to be read now so a protein can be “assembled”
Amylase – an enzyme in your mouth
Hemoglobin on Red blood cells
Process by which genetic information encoded in DNA is copied onto messenger RNA
Occurs in the nucleus
Process by which information encoded in mRNA is used to assemble a protein at a ribosome
Occurs on a Ribosome
mRNA protein as tRNA brings in its Amino Acid
