To describe: The potential mechanisms in which erroneous reaction of the immune system with self-tissue causes autoimmune diseases.
Introduction: A complex network of the specialized organs, cells, and tissues of the body that are involved in protecting it against the foreign invaders are referred to as the immune system. The purpose of this system is to keep away and destroy the infectious microbes from the body. Sometimes, inappropriate immune responses would also lead to certain diseases such as autoimmune diseases. This illness causes the immune system to act against the normal tissues of the body.

Explanation of Solution
The potential mechanisms in which the erroneous reaction of immune response with the self-tissue leads to autoimmune disease are as follows:
- The occurrence of minute alterations in the self-tissues of the body might lead to immunogenic attacks.
- During the fetal development, the occurrence that does not come in contact with the lymphocytes directly might cause autoimmune reactions. This occurs if the self-antigens are released subsequently from sequestration.
- Abnormal production of the subclasses of T lymphocytes, especially the T-suppressor cells along with the development of abnormal B cells that do not respond to the signals of suppressor T cells is also been proposed.
- The viruses might also be considered as a factor as they have the capacity of altering the self cells.
- Genetic components are also found to be a potential cause for autoimmune diseases.

- What is a gain of function mutation?arrow_forwardMolecular Biology Question: Please help. Thank you Is Southern hybridization's purpose detecting specific nucleotide sequences? How so?arrow_forwardUse the following information to answer the question(s) below. Martin Wikelski and L. Michael Romero (Body size, performance and fitness in Galápagos marine iguanas, Integrative and Comparative Biology 43 [2003]:376-86) measured the snout-to-vent (anus) length of Galápagos marine iguanas and observed the percent survival of different-sized animals, all of the same age. The graph shows the log snout-vent length (SVL, a measure of overall body size) plotted against the percent survival of these different size classes for males and females. Survival (%) 100- 80- 60- 40- 20- 0+ 1.9 T 2 2.1 2.2 2.3 2.4 2.5 2.6 2.7 Log SVL (mm) 19) Examine the figure above. What type of selection for body size appears to be occurring in these marine iguanas? A) directional selection B) stabilizing selection C) disruptive selection D) You cannot determine the type of selection from the above information. 3arrow_forward
- 24) Use the following information to answer the question below. Researchers studying a small milkweed population note that some plants produce a toxin and other plants do not. They identify the gene responsible for toxin production. The dominant allele (T) codes for an enzyme that makes the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin. Heterozygotes produce an intermediate amount of toxin. The genotypes of all individuals in the population are determined (see table) and used to determine the actual allele frequencies in the population. TT 0.49 Tt 0.42 tt 0.09 Refer to the table above. Is this population in Hardy-Weinberg equilibrium? A) Yes. C) No; there are more homozygotes than expected. B) No; there are more heterozygotes than expected. D) It is impossible to tell.arrow_forward30) A B CDEFG Refer to the accompanying figure. Which of the following forms a monophyletic group? A) A, B, C, and D B) C and D C) D, E, and F D) E, F, and Garrow_forwardMolecular Biology Question. Please help with step solution and explanation. Thank you: The Polymerase Chain Reaction (PCR) reaction consists of three steps denaturation, hybridization, and elongation. Please describe what occurs in the annealing step of the PCR reaction. (I think annealing step is hybridization). What are the other two steps of PCR, and what are their functions? Next, suppose the Tm for the two primers being used are 54C for Primer A and 67C for Primer B. Regarding annealing step temperature, I have the following choices for the temperature used during the annealing step:(a) 43C (b) 49C (c) 62C (d) 73C Which temperature/temperatures should I choose? What is the corresponding correct explanation, and why would I not use the other temperatures? Have a good day!arrow_forward
