In biological systems, structure and function are related. explain the role of membranes in two of the following cellular processes:
synthesis of proteins
formation of lysosomes
dna transcription

Dna transcription:
after the transcription of mrna from dna the mrna needs to exit the nucleus and enter the cytoplasm where it will be translated to form protein. the transcribed mrna exits the nuclear membrane via nuclear pores interspersed through out the membrane.
synthesis of proteins:
after the mrna exits the nucleus via the nuclear pores in the nuclear membrane it undergoes the process of translation.  a lot of the ribosomes responsible for the process of protein synthesis are membrane bound on the rough endoplasmic reticulum where the protein undergoes post translational modifications and additions
