RNA is single stranded, contains uracil instead of thymine and ribose instead of deoxyribose sugar.<\/li>\n<li class=\"p1\">Messenger RNA (mRNA) carries a copy of the DNA code from the nucleus to the ribosome.<\/li>\n<li class=\"p1\">Ribosomal RNA (rRNA) and proteins form the ribosome.<\/li>\n<li class=\"p1\">Each transfer RNA (tRNA) carries a specific amino acid.<\/li>\n<li class=\"p1\">Transcription of DNA into primary and mature RNA transcripts in the nucleus. This should include the role of RNA polymerase and complementary base pairing.<\/li>\n<li class=\"p1\">mRNA is transcribed from DNA in the nucleus and translated into proteins by ribosomes in the cytoplasm. RNA polymerase moves along DNA unwinding and unzipping the double helix and synthesising a primary transcript of RNA by complementary base pairing. Genes have introns (non -coding regions of genes) and exons (coding regions of genes).<\/li>\n<li class=\"p1\">The introns of the primary transcript of mRNA are non -coding and are removed in RNA splicing. The exons are coding regions and are joined together to form mature transcript. This process is called RNA splicing.<\/li>\n<li class=\"p1\">Translation of mRNA into a polypeptide by tRNA at the ribosome. tRNA folds due to base pairing to form a triplet anticodon site and an attachment site for a specific amino acid<\/li>\n<li class=\"p1\">Triplet codons on mRNA and anticodons translate the genetic code into a sequence of amino acids.<\/li>\n<li class=\"p1\">Start and stop codons exist.<\/li>\n<li class=\"p1\">Codon recognition of incoming tRNA, peptide bond formation and exit of tRNA from the ribosome as polypeptide is formed.<\/li>\n<li class=\"p1\">Different proteins can be expressed from one gene as a result of alternative RNA splicing and post -translational modification.<\/li>\n<li class=\"p1\">Different mRNA molecules are produced from the same primary transcript depending on which RNA segments are treated as exons and introns.<\/li>\n<li class=\"p1\">Post -translation protein structure modification by cutting and combining polypeptide chains or by adding phosphate or carbohydrate groups to the protein.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The following links offer some useful revision on Cell Structure to support your learning: BBC Bitesize Learner Guide BBC Bitesize Questions Biology Coach Video Lesson Gene Expression Quiz Gene Expression Mindmap Online Flashcards At Higher, you will need to know the following: Phenotype is determined by the proteins produced as the result of gene expression. &hellip; <a href=\"https:\/\/blogs.glowscotland.org.uk\/gc\/hhgeneexpression\/\" class=\"more-link\">Continue reading<span class=\"screen-reader-text\"> &#8220;Gene Expression&#8221;<\/span><\/a><\/p>\n","protected":false},"author":6619,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"open","template":"","meta":{"footnotes":""},"class_list":["post-2","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/blogs.glowscotland.org.uk\/gc\/hhgeneexpression\/wp-json\/wp\/v2\/pages\/2","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/blogs.glowscotland.org.uk\/gc\/hhgeneexpression\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/blogs.glowscotland.org.uk\/gc\/hhgeneexpression\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/blogs.glowscotland.org.uk\/gc\/hhgeneexpression\/wp-json\/wp\/v2\/users\/6619"}],"replies":[{"embeddable":true,"href":"https:\/\/blogs.glowscotland.org.uk\/gc\/hhgeneexpression\/wp-json\/wp\/v2\/comments?post=2"}],"version-history":[{"count":2,"href":"https:\/\/blogs.glowscotland.org.uk\/gc\/hhgeneexpression\/wp-json\/wp\/v2\/pages\/2\/revisions"}],"predecessor-version":[{"id":11,"href":"https:\/\/blogs.glowscotland.org.uk\/gc\/hhgeneexpression\/wp-json\/wp\/v2\/pages\/2\/revisions\/11"}],"wp:attachment":[{"href":"https:\/\/blogs.glowscotland.org.uk\/gc\/hhgeneexpression\/wp-json\/wp\/v2\/media?parent=2"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
