guanine
guanine — 名詞
1. a nitrogen-containing base found in the cells of all living things; it is one of
鳥嘌呤
DNA與RNA的四種含氮鹼基之一
a nitrogen-containing base found in the cells of all living things; it is one of just four kinds of molecule that spell out the genetic instructions in DNA and RNA — and in the DNA double helix it always pairs with cytosine
Daichi asked his biology teacher why guanine always pairs with cytosine and never with adenine in the DNA helix.
Daichi 問他的生物老師，為什麼鳥嘌呤在 DNA 螺旋中總是與胞嘧啶配對，從不與腺嘌呤配對。
guanine always pairs with cytosine in the DNA double helix
Dr. Hamza showed Anya the gene sequence, pointing to where a guanine had been replaced by adenine.
Hamza 醫師向 Anya 展示基因序列，指出鳥嘌呤被腺嘌呤取代的位置。
Lakan watched the PCR machine build new DNA strands, with guanine nucleotides slotting into place opposite every cytosine.
Lakan 看著 PCR 儀器構建新的 DNA 鏈，鳥嘌呤核苷酸在每個胞嘧啶對面卡入定位。
Jude's lab team studied how oxidised guanine in DNA can trigger the mutations that lead to skin cancer.
Jude 的實驗團隊研究 DNA 中氧化的鳥嘌呤如何引發導致皮膚癌的突變。
Zola read the DNA sequence printout, circling every guanine in yellow to check for mutations.
Zola 讀著 DNA 序列的列印稿，用黃筆圈出每一個鳥嘌呤來檢查突變。
用法筆記
Guanine is the free base; when attached to a sugar molecule it becomes guanosine, and with a sugar plus a phosphate group it forms guanylate.
