A protein must be correctly folded before it can be functional. A gene is a DNA sequence that encodes a specific protein by the sequential processes of transcription and translation.
A gene is a specific fragment of DNA that is used as a template to create a messenger RNA (mRNA) by a process called transcription.
For example, the sequence ATGTTTGGG of a gene generates a complementary UACAAACCC mRNA.
This mRNA sequence is then used as a template to create a polypeptide (in this case, Tyr-Lys-Pro) by the process of translation.
Finally, the protein must be folded to become functional.
