The dawn of the realization that biology was about information storage coincided with the

suggest genes contain a code, just as a computer program is based on numerical code. Still
so few scientists believed DNA was the molecule encoding for hereditary information. Why?

Glucose, also called grape sugar, blood sugar or corn sugar, is among the simplest and one of the primary naturally occurring sugars. produced naturally by plants as the primary photosynthesis product, it is heavily used by living beings as a main energy source and is necessary for cellular respiration. chemically, it is a monosaccharide carbohydrate and serves as a building block for complex sugars like starch.
