B. Cytokinin
C. Auxin
D. Abscisic acid

Correct Answer: Option B


Explanation:
Cytokinins are plant hormones that promote cytokinesis (cell division) and shoot initiation. They are used in tissue culture along with auxins to induce organogenesis. Auxins promote cell elongation and root initiation, gibberellins stem elongation, abscisic acid stress responses and dormancy.

Question #3
Translation, the process of protein synthesis, occurs at the:
A. Nucleus
B. Ribosome
C. Golgi apparatus
D. Mitochondria

Correct Answer: Option B


Explanation:
Translation is the process where the genetic code carried by mRNA is decoded to synthesize a specific sequence of amino acids, forming a protein. This process occurs at the ribosomes in the cytoplasm. Ribosomes read the mRNA codons and match them with the anticodons of tRNA molecules carrying the corresponding amino acids.
