Morrison & Boyd Test: Biomolecules - NEET MCQ

It is aldohexoses.

They are pentose sugar

Sugar constituent of DNA is D-2-deoxy ribose.

Protein is condensation polymer.

Complete hydrolysis of RNA yields a pentose sugar, phosphoric acid and nitrogeneous base.

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.

They are, enatiomers as 1 is R, other is S. Therefore are stereo isomers. And dextro and levo.

In protein more than 100 amino acids combine to form proteins

Keratin is fibrous protein

Peptide linkage is present in proteins formed by combination of amino acids.

Oxime is combination of carbonyl group and and hydroxyl groups.

As both acidic and basic group is present and zwittter ion is formed

Enzymes are bio catalyst

DNA fingerprinting means sequence of bases on DNA is unique for a person.

Phospholipid is esters of glycerol with phosphoric acid.

Bees wax is myricylpaimitate.

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 primary structure.

Acetyl group adds in glucose, giving acetylation reaction.

As they have polar interactions in water hence are soluble.

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

Antibody gamma globulin

Amylopectin is major component of starch.

Vitamin C is water soluble so cannot be stored in our body.
