Kev Siv Adenine Thiab Synthesis
Kev piav qhia | adenine yog ib qho ntawm purine nitrogenous cov hauv paus uas suav cov DNA thiab RNA; muaj li ntawm ob lub carbon – nitrogen nplhaib. Adenine daim ntawv cog lus nrog thymine hauv DNA thiab nrog uracil hauv RNA (saib cov cai sib piv hauv paus); Nws tseem yog ib qho tseem ceeb ntawm lwm cov lwg me me xws li adenosine triphosphate. | |
