Question

How does the presence of a nuclear envelope affect gene expression in eukaryotes? But i need all the details about the question so please explain it in details thank you so much <3

Answer 1

Eukaryotic DNA is well packed and condensed inside a membranous envelope known as nuclear envelope, which is a characteristic feature of eukaryotic cell as compared to the prokaryotic organism. Nuclear envelop is structurally a complex component of the cell and ultimately interact with the genetic material of the cell along with its packaging proteins that is histone proteins (collectively known as chromatin) and through this interaction that alter the expression of gene thus they may play significant role in the expression or regulation of genes.

Chromosomes are condensed structure where DNA packed tightly histone proteins and form octamers and several octamers make chromatin fiber. During condensation or De- condensation, process a number of post-translational modifications (epigenetic changes) occurs specially in the histone protruding tail, which result activation and inhibition of genes by nuclear envelope components. Other than this, majorly, through transcription a number of mRNAs of genes produced inside the nucleus and these needs to be exported to the cytoplasm through nuclear envelope for translation (for expression). Thus, nuclear envelope can significantly regulate the expression of genes in eukaryotic system.
