10
Q
How are proteins made
A
- DNA unzips and mRNA takes a complementary copy (replacing Thymine with Uracil)
- mRNA travels to the ribosome where it will “read” the message and make sure the right amino acids are called
- A chain of amino acids will form being held together by peptide bonds
- A chain will code for a protein
