Answer 1

Answer:

why is sucrose called a Reducing sugar?

All monosaccharides and some disaccharides are reducing sugar. Sucrose is A non reducing sugar because the carbon elements of the aldehyde groups are bonded in what's called A glycosidic bond , so that it cannot form an open-chain structure with an available aldehyde group.

name four bases present in dna?

In DNA, there are four different bases: adenine (A) and guanine (G) are the larger purines. Cytosine (C) and thymine (T) are the smaller pyrimidines. RNA also contains four different bases. Three of these are the same as in DNA: adenine, guanine, and cytosine.

hope it's help u mate.......

please mark me as brainlist

Answer 2

Answer:

The two monosaccharide units are held together by a glycosidic linkage between C1 of α-glucose and C2 of β-fructose. Since the reducing groups of glucose and fructose are involved in glycosidic bond formation, sucrose is a non-reducing sugar.

The four bases present in DNA are

adenine (A) ,

guanine (G),

cytosine (C) and

thymine (T).
