WebMaking Proteins: To make a protein, the DNA is first transcribed into messenger RNA (mRNA), which contains A, C, G and uracil (U) instead of T. This is a single stranded molecule vs. the double-stranded DNA. Cells have a huge protein and RNA machine called the ribosome that can then "read" the mRNA and translate it into protein. ct four sedan leather seats
