translation
synthesis of a polypeptide using the genetic info encodede in a mRNA molecule. there is a change of "language" from the nucleotides to amino acids
ribosomes
organelle-site of protein synthesis
RNA processing
modification of RNA before it leaves the nucleus, a process unique to eukaryotes
primary transcript
initial rna transcript, also called pre-mRNA when transcrribed from a protein-coding gene
tripled code
