Answer:DNA has three types of chemical component: phosphate, a sugar called deoxyribose, and four nitrogenous bases—adenine, guanine, cytosine, and thymine. Two of the bases, adenine and guanine, have a double-ring structure characteristic of a type of chemical called a purine.
Explanation:
Proteins are made of hundreds and thousands of polymers called Amino Acid which are attached with each other in long chains. There are 20 different types of amino acids that make up a protein
Enzymes are also known as Biological catalysts. An enzyme working at its maximum possible rate, where the substrate concentration is in excess is <span>V max.
</span><span>The reaction is slow because the molecules are moving slowly and they will not often collide with the active site of an enzyme, so the binding of an enzyme and substrate is rare.</span>
During phototropism, the plant hormone auxin<span> controls cell elongation.</span>
