All strains of human papillomavirus (HPV) are capable of integrating their double-stranded DNA viral genome into host basal cells while waiting for keratinocyte differentiation before initiating viral replication for virion shedding. As a consequence of the integrated genome, HPV strains that more readily transform host cells are more likely to cause an increased expression of viral .

Oncogenes.

Explanation:

Cancer is the harmful disease that causes several death in the world. Cancer occur due to the mutation in the genes that are responsible for the regulation of apoptosis  and cell divisions.

The virus are also oncogenic in nature and can cause several different type of cancer. The human papilloma virus can be transmitted from the skin contact. The virus cause cervical cancer and genital warts. The integration of this virus into host genome increases the expression of viral oncogenes in the host DNA.

Thus, the answer is oncogenes.

well we can't tell you because we cant see the time give a screen shot or something.

answer: that would be cheating
