Detailed explanation-1: -The eukaryotic nucleus therefore provides a distinct compartment within the cell, allowing transcription and splicing to proceed prior to the beginning of translation. Thus, in eukaryotes, while transcription occurs in the nucleus, translation occurs in the cytoplasm.
Detailed explanation-2: -Transcription occurs in the nucleus whereas the major mRNA decay pathways operate in the cytoplasm.
Detailed explanation-3: -During transcription, a piece of DNA that codes for a specific gene is copied into messenger RNA (mRNA) in the nucleus of the cell. The mRNA then carries the genetic information from the DNA to the cytoplasm, where translation occurs.
Detailed explanation-4: -Eukaryotic transcription occurs within the nucleus where DNA is packaged into nucleosomes and higher order chromatin structures.
