    E6 interacts with p53 in the host cell and promotes it's degradation via the ubiquitin dependent pathway.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because E6, a viral protein, interacts with p53, a tumor suppressor protein, in the host cell. This interaction leads to the degradation of p53 through the ubiquitin-dependent pathway.

    HPV is the number one Sexually Transmitted Disease in the US.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    HPV, or human papillomavirus, is indeed the number one sexually transmitted disease in the US. It is a common virus that can be transmitted through sexual contact and can cause various health issues, including genital warts and certain types of cancer. The high prevalence of HPV infections and its potential serious consequences make it the most common sexually transmitted disease in the country.

    Is NOT longer prevalent disease in the United States. Disease caused by varicella-zoster virus (VZV) Transmitted by skin contact and respiratory droplets

    • Shingles

    • Pneumonia

    • Herpes

    • Chickenpox

    Correct Answer
    A. Chickenpox
    Explanation
    Chickenpox is the correct answer because it is a disease caused by the varicella-zoster virus (VZV), which is transmitted by skin contact and respiratory droplets. While shingles, pneumonia, and herpes are also caused by the same virus, chickenpox is no longer prevalent in the United States due to the introduction of a vaccine.

    • Sexually transmitted HPV's

    • Kaposi sarcoma

    • HPV- induced

    Correct Answer
    A. Sexually transmitted HPV's
    Explanation
    The correct answer is sexually transmitted HPV's. This answer is supported by the statement in the question that Types 6, 11, 16, and 18 are the most important strains that are high risk and sexually transmitted. This suggests that these specific strains of HPV are transmitted through sexual activity and pose a higher risk compared to other strains.

    E7 complexes with retinoblastoma protein (Rb) thereby inactivating it.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because E7 complexes with retinoblastoma protein (Rb), which leads to the inactivation of Rb. This interaction between E7 and Rb prevents Rb from carrying out its normal function, which is to regulate the cell cycle and inhibit cell proliferation. As a result, the inactivation of Rb by E7 can contribute to uncontrolled cell growth and the development of conditions such as cancer.

    Severe Acute Respiratory Syndrome (SARS) spread through close person to person contact SARS is an emerging infectious disease of the family???? Spread by contact with an infected person or object which theyhave coughed or sneezed. BATs may be the natural host

    • Paramyxovirus

    • Paramyxoviridae

    • Coronaviridae

    • Pneumovirus

    Correct Answer
    A. Coronaviridae
    Explanation
    Coronaviridae is the correct answer because SARS is caused by a coronavirus. Coronaviruses are a family of viruses that can cause respiratory illnesses in humans and animals. SARS is known to spread through close person to person contact, as well as through contact with infected objects. The statement about bats being the natural host is unrelated to the question and does not provide an explanation for the correct answer.

    • 10-12 times a year

    • Lifetime outbreaks every month

    Correct Answer
    A. 8-10 times a year
    Explanation
    The correct answer is 8-10 times a year. Herpes simplex virus Type II can cause recurrent outbreaks, with an average of 8-10 episodes per year. These outbreaks are characterized by the presence of genital herpes sores and blisters, as well as symptoms such as genital itching and throbbing. The virus can also lead to complications such as encephalitis, neonatal herpes, and certain cancers, particularly cervical cancers. The virus can remain latent in nerve cells and may periodically reactivate, leading to recurrent episodes.
