WebAs it moves farther along the mRNA, this chain grows (Figure 2). Once a ribosome has finished reading a blueprint, it releases a protein into the cell. That ribosome is then ready to repeat the process. Viruses use our ribosomes to make their own proteins The universal use of DNA, mRNA, and amino acids is what make it possible for viruses to exist. WebTranscribed Image Text: Question 2 Which of the following is FALSE about RNA polymerase II: O Like DNA polymerase, it catalyzes a reaction that forms a phosphodiester bond O Like DNA polymerase, it moves along the template strand of DNA in the 3 to 5' direction.
