Eukaryotes or eukaryotic cells
have a cell nucleus and organelles enclosed within membranes. Eukaryotes can be
unicellular or multicellular. Most complex life forms are eukaryotes. In
contrast, prokaryotes don’t have a nucleus and don’t have things like mitochondria
or chloroplasts. Their DNA, proteins, and metabolites swim freely in the
cytoplasm and not enclosed in organelles.

expression is taking place when chromatin is less condensed. Highly compacted
chromatin is not accessible to the enzymes involved in DNA transcription,
replication and repair because transcription is being inhibited or inactive. Therefore,
looser configuration permits transcription or gene expression to take place. </span>
Answer:
Stem cells.
Explanation:
Stem cells are the undifferentiated and unspecialized cells. These cells have the ability to divide for indefinite periods. Due to their ability to divide, these cells can give rise to specialized cells. Therefore, the cells present in the mucosal surface of the gastrointestinal tract that has the ability to give rise to specialized cells are stem cells. These cells are required to replace the damaged cells with the new functional cells.
