What is a Double Helix that runs in opposite strands, 5' to 3'.
What are the functions of each RNA?
What is mRNA takes a message from DNA to ribosomes, rRNA makes ribosomes along with some proteins, and tRNA transfers amino acids to ribosomes.
What does DNA Polymerase do?
What is it makes a polymer of DNA, as well as proofreads.
What is the process of Translation?
What is that it goes from a specific DNA sequence, to the mRNA sequence, to the specific amino acid sequence.
