2025 biology talkshow : 身分與親緣的科學密碼-DNA指紋分析 (選修生物I)

詳細解釋DNA 指紋分析（DNA fingerprinting）這項關鍵的生物科技應用。闡述DNA 指紋並非手指指紋，而是透過分析DNA中稱為「短串聯重複序列」（STRs）的重複次數差異來識別個體。它深入說明STRs的遺傳原理，即子女從父母各繼承一半STRs，這使其成為親子鑑定的基礎。此外，資料還涵蓋實驗室中提取、擴增和分析DNA樣本的操作步驟，並列舉親子鑑定、犯罪鑑定和身份確認等多元實際應用。最後強調DNA指紋分析的高精確性，並探討誤判的可能性與預防措施。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://g.co/gemini/share/1d3b4a0c6b53 Powered by Firstory Hosting
