four friend has just been diagnosed with melanoma and is seeking your help. She has been told that one of her genes, which codes for a protein called BR, has a point mutation where an A replaces a T base. This results in a mutant BR protein in which a glutamic acid has replaced a valine. The mutant BR protein has much greater activity than the wild type protein and this increased activity causes increased cell division, Based on this case history, the gene coding for the normal BR protein is likely to be a: Proto-oncogene Tumor suppressor Either tumor suppressor or proto-oncogene n Dloithor tumor eupproccor nor proto oncogon

Transcribed Image Text:Your friend has just been diagnosed with melanoma and is seeking your help. She has been told that one of her genes, which codes for a protein called BR, has a point mutation where an A replaces a I base. This results in a mutant BR protein in which a glutamic
acid has replaced a valine. The mutant BR protein has much greater activity than the wild type protein and this increased activity causes increased cell division. Based on this case history, the gene coding for the normal BR protein is likely to be a:
Proto-oncogene
Tumor suppressor
Either tumor suppressor or proto-oncogene
Neither tumor suppressor nor proto-oncogene
