Describe the process, proteins and RNAs involved in transcription and translation. How do the RNAs differ in their functions (messanger, ribosomal, and transfer)?

Question

Messanger RNA starts in the nucleus during transcription and moves to the cytoplasm. Its purpose is to copy DNA (translation) and carry the message to ribosomes to make protein. 
Ribosomal RNA is formed in the nucleus, and it reads the messanger RNA and joins amino acids together to make a protein. It decodes the message from the RNA during translation.

Transfer RNA contains the anticodon, which is the opposite sequence of the mRNA codon. It transfers and brings amino acids to the ribosome as mRNA. During translation, the anticodon and codon match up and the correct amino acid is brought to the protein.

Look up transcription and translation on YouTube - this is a very space-age animation: http://www.youtube.com/watch?v=J3HVVi2k2No

Here are a couple of more basic videos: transcription: http://www.dnalc.org/resources/3d/12-transcription-basic.html and translation: http://www.dnalc.org/resources/3d/15-translation-basic.html
