RNA assists in protein synthesis and translating the genetic code. DNA unzips to form a single-strand RNA and free nucleotides pair with the unzipped bases. In RNA, the thyamine is replaced with uracil. Adenine and uracil always combine. mRNA carries the genetic code for protein. mRNA travels through the nuclear membrane to cytoplasm and attaches to a ribosome which decodes the message. Ribosomes translate the mRNA code and builds the protein with amino acids.
