The correct spelling of the word "v jun Gene" is actually "v-jun gene". This gene is a type of oncogene, which means it has the potential to cause cancer. The spelling of this gene's name may seem unusual, but it follows the conventions of scientific naming. "V-jun" indicates that the gene is a viral oncogene, while "jun" specifies the type of protein that the gene produces. In IPA phonetic transcription, this would be pronounced as "vi dʒʌn dʒin".
