Starting from the top downward:
Group 1:
- Transcription
- RNA processing
- Translation
Group 2;
- DNA
- Pre-mRNA
- mRNA
- Ribosome
- Polypeptide
The entire setup represents what happens during gene expression. The process starts in the nucleus with genetic information in DNA being transcribed into mRNA.
The pre-mRNA undergoes some processing before being transported to the cytoplasm where it gets attached to the ribosome and utilized in the synthesis of polypeptides (also known as proteins) in a process known as translation.
