2025 biology talkshow:粒線體DNA與母系演化
from 雷比特生物空中講 · host 雷比特老師
詳細說明其基本特性及其在遺傳學研究中的應用。解釋 mtDNA 之所以成為理想的研究工具，是因為它具有母系遺傳、拷貝數多、突變速率相對較高和環狀基因組小等特點。這些特性使研究者能夠利用 mtDNA 建立母系系譜，透過比對單倍型來追溯共同祖先，並藉由分子時鐘模型估計族群或物種的分化年代。同時指出 mtDNA 僅反映單一路徑的限制，強調在嚴謹的研究中應將其與細胞核 DNA 和其他證據結合使用，以獲得更全面的演化歷史。 聽完後可以自主進行線上測驗，檢視學習成效喔~(需要登入gemini) 測驗網址 https://gemini.google.com/share/9144e87e746f Powered by Firstory Hosting
