| 영문 | nucleic acid | 한글 | 핵산 |
|---|---|---|---|
| 설명 | 염기, 당, 인산으로 이루어진 뉴클레오티드가 긴 사슬 모양으로 중합된 고분자 물질. 유전이나 단백질 합성을 지배하는 중요한 물질로, 생물의 증식을 비롯한 생명 활동 유지에 중요한 작용을 한다. 구성 당인 오탄당이 리보오스인 리보핵산과 디옥시리보오스인 디옥시리보 핵산으로 나뉜다. 펜토스로서 리보스나 데옥시리보스 어느 한쪽만을 포함하며 전자를 리보핵산(RNA), 후자를 데옥시리보핵산(deoxyribonucleic acid, DNA)이라 부른다. 모두 4종류의 유기염기에 의해 특징지어지며 아데닌, 구아닌 및 시토신은 양자에 공통이다. 티민은 DNA에, 우라실은 RNA에 포함된다. DNA는 주로 핵에 존재하며 형질유전에 그리고 RNA는 세포질속에서 단백질 합성에 관여한다. 섭취된 핵산은 소화관에서 구성분자로까지 가수분해되어 흡수된다. |

| mean higher high water | <marine biology> The average height of the higher high water over a 19-year period. For shorter periods of observation, corrections are applied to eliminate known variations and reduce the result to the equivalent of a mean 19-year value. (09 Oct 1997) |

| mean high water | <marine biology> The average height of the high water over a 19-year period. For shorter periods of observation, corrections are applied to eliminate known variations and reduce the result to the equivalent of a mean 19-year value. All high-waters heights are included in the average where the type of tide is either semidiurnal or mixed. Only the higher high-water heights are included in the average where the type of tide is diurnal. So determined, mean high water in the latter case is the same as mean higher high water. (09 Oct 1997) |
| mean lower low water | <marine biology> The average height of the lower low waters over a 19-year period. For shorter periods of observations, corrections are applied to eliminate known variations and reduce the result to the equivalent of a mean 19-year value. (09 Oct 1997) |

| water | 1. To wet or supply with water; to moisten; to overflow with water; to irrigate; as, to water land; to water flowers. "With tears watering the ground."

Or 4 deg C, it is the standard for specific gravities, one cubic centimeter weighing one gram. It freezes at 32 deg Fahr. Or 0 deg C. And boils at 212 deg Fahr. Or 100 deg C. (see Ice, Steam). It is the most important natural solvent, and is frequently impregnated with foreign matter which is mostly removed by distillation; hence, rain water is nearly pure. It is an important ingredient in the tissue of animals and plants, the human body containing about two thirds its weight of water. 2. A body of water, standing or flowing; a lake, river, or other collection of water. "Remembering he had passed over a small water a poor scholar when first coming to the university, he kneeled."

Inch of water, a unit of measure of quantity of water, being the quantity which will flow through an orifice one inch square, or a circular orifice one inch in diameter, in a vertical surface, under a stated constant head; also called miner's inch, and water inch. The shape of the orifice and the head vary in different localities. In the Western United States, for hydraulic mining, the standard aperture is square and the head from 4 to 9 inches above its center. In Europe, for experimental hydraulics, the orifice is usually round and the head from 1/12 of an inch to 1 inch above its top. Mineral water, waters which are so impregnated with foreign ingredients, such as gaseous, sulphureous, and saline substances, as to give them medicinal properties, or a particular flavor or temperature. Soft water, water not impregnated with lime or mineral salts. To hold water. See Hold, To keep one's head above water, to keep afloat; fig, to avoid failure or sinking in the struggles of life. To make water. To pass urine. <medicine> Hydrothorax. Other phrases, in which water occurs as the first element, will be found in alphabetical order in the Vocabulary. Origin: AS. Waeter; akin to OS.
