MICROANATOMY

Detailed explanation-1: -In fact, that’s exactly what eukaryotic cells do with their genetic material, placing it in a membrane-enclosed repository called the nucleus. Eukaryotic DNA never leaves the nucleus; instead, it’s transcribed (copied) into RNA molecules, which may then travel out of the nucleus.

Detailed explanation-2: -Each strand of mRNA contains the instructions needed to build a particular protein. Unlike DNA, the mRNA is free to leave the nucleus via the nuclear pores, where it can then be used by the ribosomes for protein synthesis.

Detailed explanation-3: -Nuclear Membrane The nuclear membrane serves to separate the chromosomes from the cell’s cytoplasm and other contents. An array of small holes or pores in the nuclear membrane permits the selective passage of certain materials, such as nucleic acids and proteins, between the nucleus and cytoplasm.
