Final answer:
Viruses do not carry promoters that stimulate cellular oncogenes.
Step-by-step explanation:
False.
Viruses do not carry promoters that stimulate cellular oncogenes. Instead, viruses can cause cancer by either introducing genes that stimulate unregulated cell growth (oncogenes) or by interfering with the expression of genes that inhibit cell growth. This interference with the normal regulation of the host cell cycle can lead to the development of cancer.
