• Transcription / ribosomes

• Translation / ribosomes

• Translation / nucleus

• Transcription / nucleus

There are 3 main types of RNA that we are studying. Ribosomal RNA (rRNA) along with proteins help build the ribosome. What is the role of mRNA?

• The role of mRNA is to carry the amino acid from the nucleus to the ribosome.

• The role of mRNA is to work with the rRNA and help create the ribosome.

• The role of mRNA is to carry the genetic information from the nucleus to the ribosome so that the correct protein can be made.

• The role of mRNA is to help make proteins by transferring the amino acids from the cytoplasm.
