基因是什麼?可以這樣粗略解釋:我們若要建造一所房子,須先把圖則畫出來;房子愈大愈考究,圖則會愈多愈複雜。若要製造一個人,最先的「原料」只是一個卵子加一個精子,處於母體內。在大約十個月當中,這兩者結合,先成為胚胎,之後一步一步成長,直到瓜熟蒂落、新生命離開母體出世為止。其中的生長發展極其繁瑣,但能按部就班,有條不紊;所依仗的,正是一整套詳盡的「圖則」。在建築工程中用的圖則(所謂「藍圖」)是寫在紙上的,用筆墨顏色顯示出來;在人體生長過程中的藍圖,則是用一種化學分子表達的,這分子叫「脫氧核糖核酸」(Deoxyribonucleic acid),縮寫為DNA;表達的方法,像英文字,每一個「字」一般用三個「字母」組成,一連串的這些「字」,就能將「建造」(人體生長)中的指令一一羅列清楚。所以說,這些DNA攜帶有「遺傳訊息」;另一方面,我們將DNA「攜帶的遺傳訊息」,稱之為「基因」。「基因」(Gene)一詞來自希臘語,意思為「生」,指的是DNA序列,是基本的遺傳「指示單位」。顧小培
基因的操作,乃是通過指導「蛋白質合成」,將自己所攜帶的「遺傳訊息」付諸實行,從而控制生物的生長。這些藍圖(基因)有多少?以人類而言,約有兩萬至兩萬五千個。

人工智能研究去氧核糖核酸 DNA
去氧核糖核酸(Deoxyribonucleic acid,DNA)是構成細胞遺傳信息的核酸分子。人工智能在研究DNA方面也發揮著重要的作用。具體來說,人工智能可以應用在DNA序列的識別、分類、比對、組裝等方面。其中,DNA序列比對是一項關鍵的技術,可以通過比對不同個體的DNA序列來識別遺傳變異和突變,進而研究相關疾病的發生和治療。另外,人工智能還可以應用於基因表達譜的分析,通過挖掘基因表達與疾病關聯的信息,研究相關的治療方法。
近年來,人工智能還應用在DNA合成方面,利用機器學習算法進行設計和優化,提高DNA合成的效率和準確性。此外,人工智能還可以應用在基因編輯領域,通過設計和優化基因編輯工具,實現對DNA序列的精確編輯和修覆,為基因治療提供有力支持。
Deoxyribonucleic acid, or DNA, is a complex molecule that contains the genetic instructions for the development and function of all living things. DNA is a long, double-stranded helix made up of nucleotides, which are the building blocks of DNA. Each nucleotide consists of a sugar molecule, a phosphate group, and a nitrogenous base. There are four types of nitrogenous bases in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). The sequence of these nitrogenous bases determines the genetic information stored in DNA.
DNA is organized into structures called chromosomes, which are located in the nucleus of a cell. Humans have 23 pairs of chromosomes, which contain all of the genetic information needed to build and maintain the body. This genetic information is organized into genes, which are sequences of DNA that provide instructions for making specific proteins. Proteins are the building blocks of the body and play critical roles in many biological processes.
The structure and function of DNA are maintained through a process called replication, which is the duplication of DNA. Replication is an essential part of cell division, as it ensures that each new cell has an exact copy of the genetic information stored in the original cell's DNA.
DNA is a crucial molecule in biology, and its discovery revolutionized the field of genetics. Today, the study of DNA and genetics is used in a wide range of applications, including genetic testing, forensics, and the development of new treatments for genetic diseases.
