APAKAH MAKSUD CODON dalam CORSICA?
Kod genetik
Kod genetik adalah set peraturan yang mana maklumat yang dikodkan dalam bahan genetik diterjemahkan ke dalam protein oleh sel hidup. Penyahkodan biologi dicapai oleh ribosom, yang menghubungkan asid amino dalam urutan yang ditentukan oleh mRNA, menggunakan pemindahan molekul RNA untuk membawa asid amino dan membaca tiga nukleotida mRNA pada satu masa. Kod genetik sangat serupa di antara semua organisma dan boleh dinyatakan dalam jadual mudah dengan 64 penyertaan. Kod ini menentukan bagaimana urutan ketiga-tiga nukleotida ini, yang disebut kodon, menentukan asid amino yang akan ditambahkan seterusnya semasa sintesis protein. Dengan beberapa pengecualian, kodon tiga nukleotida dalam urutan asid nukleik menentukan asid amino tunggal. Kerana sebahagian besar gen dikodkan dengan kod yang sama, kod tertentu sering disebut sebagai kod genetik kanonik atau standard, atau hanya kod genetik, walaupun sebenarnya beberapa kod variasi telah berkembang. Sebagai contoh, sintesis protein dalam mitokondria manusia bergantung kepada kod genetik yang berbeza daripada kod genetik standard.
Definisi codon dalam kamus Corsica
Takrif codon dalam kamus adalah satu unit yang terdiri daripada tiga pangkalan yang bersebelahan pada molekul DNA dan yang menentukan kedudukan asid amino tertentu dalam molekul protein semasa sintesis protein.
