Following chemical activation and in-vitro culture, the developed blastocysts are transferred into recipient mothers to deliver the Gir calf.<\/li>\n<\/ul>\n<h3>What is cloning?<\/h3>\n<ul>\n<li>The term cloning describes a number of different processes that can be used to produce <strong>genetically identical copies of a biological entity.<\/strong><\/li>\n<li>Cloning can be <strong>natural or artificial<\/strong>. Examples of cloning that occur naturally are as follows:\n<ul>\n<li><strong>Vegetative reproduction<\/strong> in plants, e.g. water hyacinth producing multiple copies of genetically identical plants through apomixis<\/li>\n<li>Binary fission in bacteria.<\/li>\n<\/ul>\n<\/li>\n<li>Clones can also be produced through artificial means. Biotechnological methods are employed to produce such clones.\n<ul>\n<li><strong>Molecular cloning<\/strong>, where copies of specific gene fragments are produced<\/li>\n<li><strong>Cellular cloning<\/strong>, where single-celled organisms with the exact genetic content of the original cell are produced in cell cultures.<\/li>\n<li><strong>Organism cloning,<\/strong> or reproductive cloning, where a multicellular clone is created generally through somatic cell nuclear transfer<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h3>What are somatic cells?<\/h3>\n<ul>\n<li>The word \u201csomatic\u201d is derived from the Greek word soma, meaning \u201cbody\u201d. Hence, all body cells of an organism \u2013 apart from the sperm and egg cells, the cells from which they arise (gametocytes) and undifferentiated stem cells \u2013 are somatic cell.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<hr \/>\n<h3>Q1) What is vegetative reproduction?<\/h3>\n<p>Vegetative reproduction is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment of the parent plant or grows from a specialized reproductive structure (such as a stolon, rhizome, tuber, corm, or bulb).<\/p>\n<p><strong>Source:<\/strong>\u00a0<a href=\"https:\/\/economictimes.indiatimes.com\/news\/india\/haryana-indias-first-cloned-desi-gir-female-calf-ganga-produced-at-ndri\/articleshow\/99050100.cms?from=mdr\" target=\"_blank\" rel=\"nofollow noopener\"><u>Haryana: India&#8217;s first cloned desi Gir female calf, Ganga produced at NDRI<\/u><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cloning describes a number of different processes that can be used to produce genetically identical copies of a biological entity.<\/p>\n","protected":false},"author":5,"featured_media":6814,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-6813","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-upsc-prelims-current-affairs","8":"no-featured-image-padding"},"acf":[],"_links":{"self":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/6813","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/comments?post=6813"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/6813\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/6814"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=6813"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=6813"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=6813"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
