已经发现了一组基因。称癌基因,癌基因最初是在一组致癌病毒中确定出来的,这组病毒在动物中可诱发肿瘤,在组织培养中通常也具有转化细胞的能力。这组转化病毒属于逆转录病毒。该病毒基因组是一种RNA分子。在绝大多数脊椎动物类中均已发现有这些病毒。这种病毒在动物宿主中可转为一种重要的基因,且有致癌的潜能。 A group of genes has been discovered. Oncogenes, oncogenes, were originally identified in a group of oncogenic viruses that can induce tumors in animals and often have the ability to transform cells in tissue culture. This set of transforming viruses is a retrovirus. The viral genome is an RNA molecule. These viruses have been found in most vertebrate species. This virus can be converted into an important gene in animal hosts and has the potential to cause cancer.
