APAKAH MAKSUD RIBOZYME dalam CORSICA?
Ribozyme
Ribozim adalah molekul RNA yang mampu memangkinkan tindak balas biokimia tertentu, sama seperti tindakan enzim protein. Penemuan ribozim 1982 menunjukkan bahawa RNA boleh menjadi kedua-dua bahan genetik dan pemangkin biologi, dan menyumbang kepada hipotesis dunia RNA, yang menunjukkan bahawa RNA mungkin penting dalam evolusi sistem mereplikasi diri prebiotik. Juga dikenali sebagai RNA pemangkin, ribozim berfungsi dalam ribosom untuk menghubungkan asid amino semasa sintesis protein, dan dalam pelbagai reaksi pemprosesan RNA, termasuk splicing RNA, replikasi virus, dan pemindahan biosintesis RNA. Contoh-contoh ribozim termasuk ribozyme hammerhead, ribozyme VS dan ribozyme rambut. Penyiasat yang mengkaji asal usul kehidupan telah menghasilkan ribozim di makmal yang mampu memangkinkan sintesis mereka sendiri dalam keadaan yang sangat spesifik, seperti ribozyme polimerase RNA. Mutagenesis dan pemilihan telah dilakukan untuk mengasingkan varian diperbaiki ribozyme polimerase "Round-18" dari 2001. "B6.
