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.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
