Estrogen and testosterone are non polar in nature.They can easily pass the cell mambrane which is made up of lipid bilayer.After entering the cell they bind to their intracellular receptors present in the cytoplasm.
The receptor hormone complex moves to the nucleus and perform transcription and later on translation of desired proteins.
Estrogen helps in the functioning of reproductive system as it supports growth and differentiation.Whereas testosterone is important for sertoli cells which help in the process of spermatogenesis i.e formation of sperm.
Answer:
Well, on one hand, this is a good thing as negative effects of the high demand for wood such as deforestation can be minimised. This will also sustain the supply of wood for several applications. However, there could be negative consequences of propagating such genetically-modified trees, which were not stated or are not yet known.
