Transcription Process by which a DNA sequence is copied to produce a complementary RNA. In other words, it is the transfer of genetic information from DNA into RNA. Like replication , but making RNA. Beginning of the process that ultimately leads to the translation of the genetic code (via mRNA) into a protein . Image: Transcription , National Human Genome Research Institute.

Types of RNA Images: Blueprint, clipart; Factory , Andreas Praefcke; Truck , PRA. Genetic information copied from DNA is transferred to 3 types of RNA : __________ RNA: mRNA Copy of information in DNA that is brought to the ribosome and translated into protein by tRNA & rRNA. __________ RNA: rRNA Most of the RNA in cells is associated with structures known as ribosomes, the protein factories of the cells. It is the site of translation where genetic information brought by mRNA is translated into actual proteins. ___________ RNA: tRNA Brings the amino acid to the ribosome that mRNA coded for.
