"denaturing" 的音標(biāo)為 [?den??tre????] 。

基本翻譯為“使變性；使喪失性質(zhì)”。

速記技巧：可以與“變性”、“變質(zhì)”等詞聯(lián)想記憶。

Denaturing這個(gè)詞的英文詞源可以追溯到拉丁語(yǔ)“denatus”，意為“變形”或“變性”。它的主要含義是指使蛋白質(zhì)等生物分子失去原有的結(jié)構(gòu)或形態(tài)，使其變得不穩(wěn)定或易于改變。

變化形式：在詞源中，“denature”是其常用的變化形式，表示使蛋白質(zhì)等生物分子變性或改變其性質(zhì)。

1. Denaturation - 變性作用，蛋白質(zhì)等生物分子的變性過(guò)程。

2. Denaturing agent - 變性劑，用于使蛋白質(zhì)等生物分子失去原有結(jié)構(gòu)的物質(zhì)。

3. Denaturing condition - 變性條件，指使蛋白質(zhì)等生物分子變性的特定環(huán)境或條件。

4. Denaturation gradient - 變性梯度，指在特定溫度或pH值下蛋白質(zhì)等生物分子逐漸變性的過(guò)程。

5. Denaturing gradient gel electrophoresis (DGGE) - 變性梯度凝膠電泳，一種用于分析基因組DNA序列的技術(shù)。

6. Denaturing potential - 變性潛能，指在特定條件下可能使蛋白質(zhì)等生物分子變性的程度。

7. Denaturing gradient - 變性梯度，指在溶液中蛋白質(zhì)等生物分子的變性程度隨溶液性質(zhì)變化的趨勢(shì)。

8. Denaturing temperature - 變性溫度，指使蛋白質(zhì)等生物分子失去原有結(jié)構(gòu)的特定溫度。

9. Denaturation time - 變性時(shí)間，指使蛋白質(zhì)等生物分子變性所需的時(shí)間。

10. Denaturation-renaturation - 變性-復(fù)性，指蛋白質(zhì)等生物分子在變性后再?gòu)?fù)原的過(guò)程。

英文小作文：

Denaturing is a process that changes the structure of a protein or DNA from a tightly packed, ordered state to a more disordered state, which can be observed as a loss of color or shape changes. This process is often necessary for further analysis of the protein or DNA, such as sequencing or cloning, because it allows for easier separation and manipulation of the individual components.

In this process, various methods can be used to denature the protein or DNA, including heating, exposure to chemicals, and exposure to high-pressure conditions. Each method has its own advantages and disadvantages, and the choice of method depends on the specific application and requirements.

For example, heating is often the simplest and most convenient method for denaturing proteins, but it can also be harmful to some proteins if done too quickly or at high temperatures. In contrast, exposure to chemicals can be more specific and targeted, but it can also be more harmful to the environment and human health if not properly controlled. Therefore, it is important to carefully consider the methods used for denaturing proteins or DNA, and to ensure that they are safe, effective, and environmentally friendly.
