What is the molecular for Mendel's tall and dwarf plants?

Explanation

A single gene with two alleles controls the height of the pea plant. The difference in height of plant is due to:
(i) The pea plant cells have the ability of converting a precursor molecule of gibberellins into an active form `(GA_(1))`.
(ii) Theh dominant allele of the gene (Le), that codes for a protein, an functional enzyme, whichh helps in the gibberellin synthesis pathway and catalyzes the production of gibberellins (GAI). When the allele is dominant even if it is double (Le Le) or single (Le le) it produces gibberellins resulting in tall plants. The dwarf pea plants, which have two recessive alleles (le le) cannot code for functional protein resulting in dwarf plants.
