Transcription    Transcription is used to create RNA fro         m DNA. When transcription occurs, the bases of thymine, adenine, guanine, cytosine, and uracil are matched up.    Thymine and Adenine match up         Guanine and Cytosine match up In RNA, Uracil and Adenine match         up In transcription, RNA polymerase binds to the promoter of a specific gene and DNA makes a complimentary copy of that gene's base sequence using RNA nucleotides. 

Translation Translation is the process of assembling proteins from RNA and assembling polypeptides from information encoded in mRNA. Messenger RNA(mRNA) is made in the nucleus and travels out to the ribosome to carry the "message" of the DNA. At the ribosome the message will be translated into an amino acid sequence. Transfer RNA (tRNA) carries the amino acids to the site of protein synthesis on the ribosome. In tRNA the anticodon, matches the codon on the RNA strand. Condons are sets of three bases that code for a single amino acid. Anticodons consist of three bases as well. A single tRNA has one amino acid attached to it.
