RNA is very similar to DNA. Unlike DNA, RNA is ribonucleic acid instead of deoxyribonucleic acid. This means that the sugar structure on RNA is different than DNA. But that isnt the only difference. On DNA, the base pairs are AT and CG. On RNA, the base pairs are AU and CG, U or Uracil replaces Thymine. RNA also is just a singular strand. This strand is able to travel outside the nucleus since its smaller size allows it to slip through nuclear pores. Outside the nucleus, RNA is able to code for protein. To do this, the RNA strand is 'scanned' three nucleotides at a time to pair to a different amino acid. These amino acids are strung together to create protein. These proteins give organisms their hair type or eye color.
