RNA plays important roles in many cellular processes, particularly those associated with protein synthesis: transcription, RNA processing, and translation.

Drag the labels to the appropriate bins to identify the step in protein synthesis where each type of RNA first plays a role. If an RNA does not play a role in protein synthesis, drag it to the “not used in protein synthesis” bin.

And where are the labels?

1. DNA is transcribed into mRNA.

2. mRNA goes out of the nucleus and goes to the ribosome.

3. mRNA in the ribosome attracts the tRNA (which itself attracts amino acids).

4. The combination of both mRNA and tRNA causes the codon in the mRNA to meet its anticodon in the tRNA. This is successively done, leading to the lengthening of the Amino Acid chain.

5. After the Stop codon, the Amino Acid chain is cleaved into the cytoplasm and is not called a Protein.

 Transcription in bacteria
The diagram below shows a length of DNA containing a bacterial gene.
Drag the labels to their appropriate locations in the diagram to describe the function or characteristics of each part of the gene. Not all labels will be used.
