D – ribose and 2 – deoxy – D – ribose are
They are pentose sugar
The sugar constituent of DNA is.
Sugar constituent of DNA is D-2-deoxy ribose.
Protein is condensation polymer.
Complete hydrolysis of RNA yields
Complete hydrolysis of RNA yields a pentose sugar, phosphoric acid and nitrogeneous base.
The spatial arrangement of the molecule is denoted by
D and L denotes configuration and D correctly represents the OH group is on RHS on 2nd last Carbon whereas L for LHS
"d" and "l" are used for dextro and laevo.
Hence A is correct.
Choose the appropriate answer(s) for the below representation from the options given
They are, enatiomers as 1 is R, other is S. Therefore are stereo isomers. And dextro and levo.

Fibrous protein is.
Keratin is fibrous protein
The bond –CO–NH– is called
Peptide linkage is present in proteins formed by combination of amino acids.
Oxime is formed by treating glucose with
Oxime is combination of carbonyl group and and hydroxyl groups.
In aqueous solution, amino acids behave like:
As both acidic and basic group is present and zwittter ion is formed
Enzymes are used in the reaction as they are
Enzymes are bio catalyst
DNA fingerprinting means the
DNA fingerprinting means sequence of bases on DNA is unique for a person.
Phospholipid is esters of glycerol with phosphoric acid.

Example of a typical homopolysaccharide is
Polysaccharides are branched or unbranched polymer of monosaccharides. Homopolysaccharides contain a single type of monomers, .e.g., starch, glycogen, cellulose etc.
The most appropriate structure for knowing about the sequence of nucleotides in the DNA chain is
The most appropriate structure for knowing about the sequence of nucleotides in the DNA chain is primary structure.
Acetylation of glucose yields
Acetyl group adds in glucose, giving acetylation reaction.
Which of the following is most soluble in water?
As they have polar interactions in water hence are soluble.
Which one is not the essential amino acid in the ones given below?
The correct answer is option C
Leucine is an essential, branched-chain amino acid (BCAA), required for the growth and repair of muscle, skin and bone. Leucine is suspected to be the only amino acid that can stimulate muscle growth and help prevent the deterioration of muscle with age
