Question

Gibberellic acid stimulates the cells of germinating grass seeds to produce mrna molecules that code for hydrolytic enzymes. In this case the role of gibberellic acid can best be described as that of

Answer 1

In this case, Gibberellic acid acts as a transcription regulator

Step-by-step explanation:

Gibberellic acid is a hormone that activates the transcription of genes during growth. The genes that encode for regulators of the gibberellin signaling pathway were manipulated in order to increase grain yields during the green revolution

Answer 2

A regulator of gene activity.

Step-by-step explanation:

A regulator gene is responsible for controlling of gene expression either it can be one gene or more genes.

Here in above scenario, it is also an example of gene regulator. Basically, gibberellic acid is a hormone present in plant or fungi. It helps in the expression of hydrolytic enzymes by transcription of gene into mRNA and help in the growth and elongation of cells.
