Blog for 12/14

The steps for protein synthesis are:
1. The cell gets a message to make a certain kind of protein.
2. A part of the DNA unwinds, showing the gene responsible for the protein
3. With the help of enzymes, the nucleotides move one strand of the exposed gene and make a m-RNA
molecule
4. Many copies of m-RNA are made according to the amount ordered; they leave the nucleus through
the nuclear pores in to the cytoplasm.
5. An m-RNA connects with a ribosome so that the m-RNA could be decoded; the message is read a
codon at a time.
