Antigen<br>b. Bacterium<br>c. Epitope<br>d. B cell<br>e. Virus<\/p>\n\n\n\n<p><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-ast-global-color-6-color\"><strong>The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n<p>The correct answer is <strong>c. Epitope<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<p>Monoclonal antibodies are laboratory-produced molecules designed to mimic the immune system\u2019s ability to fight off harmful pathogens such as viruses and bacteria. They are created by cloning a single type of immune cell called a <strong>B cell<\/strong>, which produces antibodies against a specific antigen. These antibodies recognize and bind to a specific target on the antigen known as an <strong>epitope<\/strong>.<\/p>\n\n\n\n<p>An <strong>epitope<\/strong> (also referred to as an antigenic determinant) is the specific part of an antigen that is recognized by an antibody. The antigen itself can be a part of a bacterium, virus, or other foreign substance, but the monoclonal antibody targets only a particular epitope on that antigen.<\/p>\n\n\n\n<p>Here&#8217;s how the process works:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>B Cell Selection<\/strong>: First, a B cell that produces antibodies against a specific antigen is selected. In the case of monoclonal antibody production, this B cell is often obtained from an animal (commonly a mouse).<\/li>\n\n\n\n<li><strong>Cloning<\/strong>: This B cell is then fused with a myeloma (cancer) cell, which allows the creation of a hybrid cell called a <strong>hybridoma<\/strong>. These hybridoma cells can divide indefinitely while producing large quantities of the specific antibody against the epitope of interest.<\/li>\n\n\n\n<li><strong>Purification<\/strong>: The monoclonal antibodies produced by these hybridomas are harvested and purified for use in research, diagnostics, or treatment.<\/li>\n<\/ol>\n\n\n\n<p>The key characteristic of monoclonal antibodies is that they are <strong>monospecific<\/strong>, meaning they bind only to one specific <strong>epitope<\/strong> on the target antigen. This specificity makes monoclonal antibodies very useful in various applications like targeted therapies for cancer, autoimmune diseases, and diagnostic tests for specific pathogens.<\/p>\n\n\n\n<p>In contrast, polyclonal antibodies are mixtures of antibodies that recognize different epitopes on the same antigen, providing a broader immune response.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why Other Options Are Incorrect:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>a. Antigen<\/strong>: Monoclonal antibodies are specific to a part of the antigen, the epitope, not the entire antigen.<\/li>\n\n\n\n<li><strong>b. Bacterium<\/strong>: Monoclonal antibodies do not recognize entire bacteria, but specific molecules or epitopes on the bacteria.<\/li>\n\n\n\n<li><strong>d. B cell<\/strong>: Monoclonal antibodies do not recognize B cells; they are designed to bind to antigens or epitopes on foreign molecules.<\/li>\n\n\n\n<li><strong>e. Virus<\/strong>: Monoclonal antibodies do not recognize entire viruses but rather specific epitopes on viral proteins.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Monoclonal antibodies recognize a single: a.
