  3. Virulence

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Atopy is the condition which has been developed due to exposure to allergens in which the person is susceptible to allergic reactions. This is an inherited syndrome. The person is more likely to develop the allergic reactions like rash, rhinitis, asthma, etc when encountered with the allergen.

In human beings, retrovirus is considered as a cause of cancer because

  1. Their genome contains oncogene

  2. Their hereditary material made up of single stranded RNA.

  3. They have a gene for reverse transcriptase.

  4. Their genome may contain proto-oncogene
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A retrovirus has been identified as a single-stranded positive sense RNA virus which has an intermediate DNA that helps it target the host cell as an obligate parasite. This virus reverses the usual pattern and uses its transcriptase enzyme to produce DNA. The transmission of these viruses been generally cell-to-cell. In human beings, cancer can be triggered by proto-oncogenes present in the retrovirus which are mistakenly incorporated into proviral DNA or by the disruption of the cellular proto-oncogenes

Cancer is a disorder of cell growth in a part of the body

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • Cancer is a class of diseases characterized by out-of-control cell growth. There are over 100 different types of cancer, and each is classified by the type of cell that is initially affected.
  • Cancer harms the body when damaged cells divide uncontrollably to form lumps or masses of tissue called tumors. Tumors can grow and interfere with the digestive, nervous, and circulatory systems, and they can release hormones that alter body function. Tumors that stay in one spot and demonstrate limited growth are generally considered to be benign.
So, the correct option is 'True'

Transformation of $C$. one into oncogene is known as?

  1. Carcinogen

  2. Oncogenic transformation

  3. Neoplastic cell

  4. Cancer cell
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Transformation of C.one into oncogene is known as carcinogen. A carcinogen is any substance, radionuclide or radiation that promotes carcinogenesis, the formation of cancer. This may be due to the ability to damage the genome or to the disruption of cellular metabolic processes. 
So the correct option is 'Carcinogen'.

Which of the following changes would you find in the disease polycythemia?

  1. Increase in total WBCs

  2. Decrease in total RBCs

  3. Increase in total RBCs

  4. Decrease in total WBCs
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

 Polycythemia is a disease state in which the hematocrit (the volume % of RBC in the Blood) is elevated.It can be due to an increase in the number of RBC ("absolute polycythemia") or to a decrease in the volume of plasma ("relative polycythemia").

So, he correct option is C. ( Increase in total RBC )

'Philadelphia chromosome' is found in the patient suffering from

  1. Insomnia

  2. Leukaemia

  3. Hepatitis

  4. Albinism
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

'Philadelphia chromosome' is found in the patient suffering from leukaemia. The main cause is a genetic abnormality in chromosome 22 of leukaemia cancer cells. The chromosome is short due to a reciprocal translocation between chromosome 9 and chromosome 22 and contains a fusion gene called BCR-ABL1 which is juxtaposed onto the BCR gene of chromosome 22, coding for a hybrid protein, a tyrosine kinase signalling protein which causes rapid multiplication of the cell.

So, the correct answer is 'Leukaemia'.

D Correct answer
Explanation

Oncogenes are genes that has the potential to cause cancer.
Estrogens are a group of hormones that are important for female sexual and reproductive development.
Carcinogens are substances, radionuclide or radiation that is an agent directly involved in causing cancer.
