(b) Nucleotides
(c) Bases
(d) Sugars
Nucleic acids are the polymers of ______________.
(a) Nucleosides
(b) Nucleotides
(c) Bases
(d) Sugars
This is a Multiple Answer Type Questions as classified in NCERT Exemplar
The Correct option is b.
Nucleic acids are nucleotide polymers linked together by phosphodiester linkage. DNA and RNA are two examples. Nucleotides are formed by linking of nucleosides with three phosphate groups consuming a sign

(a) 5’and 3′
(b) Y and 5′
(c) 5′ and 5′
(d) 3’and 3′
Dinucleotide is obtained by joining two nucleotides together by phosphodiester linkage. Between which carbon atoms of pentose sugars of nucleotides are these linkages present?
(a) 5’and 3′
(b) Y and 5′
(c) 5′ and 5′
(d) 3’and 3′
This is a Multiple Answer Type Questions as classified in NCERT Exemplar
(a) 5′ and 3′ linkages are present between pentose sugars of nucleotides.
Phosphodiester links the two nucleotides together to form a dinucleotide.
Between the pentose sugars of nucleotides, there are 5′ and 3′ connections. In th
Which of the following acids is a vitamin?
(a) Aspartic acid
(b) Ascorbic acid
(c) Adipic acid
(d) Saccharic acid
Which of the following acids is a vitamin?
(a) Aspartic acid
(b) Ascorbic acid
(c) Adipic acid
(d) Saccharic acid
This is a Multiple Answer Type Questions as classified in NCERT Exemplar
Ans: The Correct option is b.
Ascorbic acid is the chemical name for vitamin C. Aspartic acid is an amino acid, adipic acid is a dicarboxylic acid with an eight-carbon chain, and saccharic acid is a dicarboxylic acid made by
In disaccharides, if the reducing groups of monosaccharides i.e., aldehydic or ketonic groups are bonded, these are non-reducing sugars. Which of the following disaccharide is a non-reducing sugar?
In disaccharides, if the reducing groups of monosaccharides i.e., aldehydic or ketonic groups are bonded, these are non-reducing sugars. Which of the following disaccharide is a non-reducing sugar?
This is a Multiple Answer Type Questions as classified in NCERT Exemplar
Ans: The Correct option is b.
The structure described in option (b) reflects sucrose, which has a C1−C2 glycosidic bond between α−D− glucose and β−D− fructose.
This is a non-reducing sugar since the reducing groups of glucose
Proteins are found to have two different types of secondary structures viz. α -helix and β - pleated sheet structure. α -helix structure of protein is stabilised by
(a) Peptide bonds
(b) Van der Waals forces
(c) Hydrogen bonds
(d) Dipole-dipole interactions

(a) Peptide bonds
(b) Van der Waals forces
(c) Hydrogen bonds
(d) Dipole-dipole interactions
This is a Multiple Answer Type Questions as classified in NCERT Exemplar
Hydrogen bonds hold the α− helical structure of proteins together. A polypeptide chain creates all potential hydrogen bonds by twisting into a
right-handed helix with the −NH group of each amino acid residue hydrogen linked to a>
Which of the following pairs represents anomers?
Which of the following pairs represents anomers?
This is a Multiple Answer Type Questions as classified in NCERT Exemplar
The configuration of different anomers at C-I is distinct. It is known as the form if the hydroxyl group (-OH) is present on the right side of anomeric carbon, and it is known as the? form if the hydroxyl group is present

(a) 2 molecules of glucose
(b) 2 molecules of glucose +1 molecule of fructose
(c) 1 molecule of glucose +1 molecule of fructose
(d) 2 molecules of fructose
Sucrose (cane sugar) is a disaccharide. One molecule of sucrose on hydrolysis gives _________.
(a) 2 molecules of glucose
(b) 2 molecules of glucose +1 molecule of fructose
(c) 1 molecule of glucose +1 molecule of fructose
(d) 2 molecules of fructose
This is a Multiple Answer Type Questions as classified in NCERT Exemplar
Sucrose is a disaccharide (sometimes known as cane sugar). One molecule of glucose and one molecule of fructose are produced when sucrose is digested. The reaction is depicted in the diagram below.
Correct option is c.
