I'd go with A, if I were you.
1st step: Transcription
DNA is unraveled and used as a template to form complimentary mRNA
mRNA then leaves nucleus in order to attach to ribosome and start 2nd step.
2nd step: Translation
tRNA with aminoacids attached will try to join mRNA\ribosome complex if tRNA triple codon matches the mRNA code it will attach aminoacid to start forming protein. This process continues until mRNA reaches STOP code, resulting in a long chain of aminoacids.
3rd step: Protein folding and modification
Usually performed by chaperonins and eventually golgi complex. Chaperonins assist in proper protein folding, while golgi apparatus performs final modifications.
Is there a question or are you asking
A tree is renewable because it can re grow and make more trees.
Iron is non renewable because it can’t make any more things, you can just use it that one time
