Brassinosteroids are also required for promotion of cell

elongation by gibberellins, and gibberellin-induced degradation of the DELLA repressor enhances the brassinosteroid response

#Unit 3. Fundamental Processes

There are two major steps to start translation

1. Activation of amino acids,

2. Assembly of ribosomes.
