Virtually all of the specialized cells of multicellular organisms
Question 83 ?options:
contain more genetic material than less specialized cells of the same organism.
contain less genetic material than less specialized cells of the same organism.
develop through mutation from less specialized cells of the organism.
have the same amount of DNA and the same number of chromosomes as all other cells of the organism and develop from the same basic stem cell<\/p>\n\n\n\n
The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n The correct answer is:<\/p>\n\n\n\n “have the same amount of DNA and the same number of chromosomes as all other cells of the organism and develop from the same basic stem cells.”<\/strong><\/p>\n\n\n\n Specialized cells in multicellular organisms are those that perform specific functions, such as muscle cells, nerve cells, or red blood cells. Despite their functional and structural differences, these specialized cells typically contain the same amount of DNA and the same number of chromosomes as the organism’s less specialized cells. This principle arises from the fact that all cells originate from a common ancestor cell through a process of cell division.<\/p>\n\n\n\n This demonstrates how the same genetic material supports diverse functions in multicellular organisms.<\/p>\n\n\n\n Virtually all of the specialized cells of multicellular organisms Question 83 ?options:contain more genetic material than less specialized cells of the same organism.contain less genetic material than less specialized cells of the same organism.develop through mutation from less specialized cells of the organism.have the same amount of DNA and the same number of chromosomes as […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[25],"tags":[],"class_list":["post-187355","post","type-post","status-publish","format-standard","hentry","category-exams-certification"],"_links":{"self":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/187355","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/comments?post=187355"}],"version-history":[{"count":0,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/187355\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/media?parent=187355"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/categories?post=187355"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/tags?post=187355"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Explanation:<\/h3>\n\n\n\n

The cells in a multicellular organism arise from a single fertilized egg cell, which undergoes numerous rounds of mitotic division to form the organism’s body. During mitosis, the DNA in the parent cell is duplicated and distributed equally to the daughter cells. Thus, all somatic (non-reproductive) cells in an organism contain an identical set of DNA.<\/li>\n\n\n\n
While all cells in the body have the same genetic material, they do not express all of their genes simultaneously. Instead, specific genes are activated or deactivated, depending on the cell’s function. For example, muscle cells activate genes involved in contraction, while nerve cells express genes critical for transmitting signals.<\/li>\n\n\n\n
Specialized cells develop from unspecialized precursor cells known as stem cells. Stem cells have the potential to differentiate into various cell types. During differentiation, stem cells undergo changes in gene expression, leading to the formation of specialized cells. This process does not alter the DNA content; it only changes how the genes are used.<\/li>\n\n\n\n\n
