Where does DNA replication occur?

In eukaryotic cells, DNA replication occurs in the nucleus. In prokaryotic cells, DNA replication occurs in the nucleoid region. 

DNA replication is the process in which two identical daughter strands of DNA are created from a single parent DNA strand. 

Eukaryotic cells, such as plant and animal cells, have a membrane-bound nucleus that houses the DNA and this is where replication occurs. 

Prokaryotic cells do not have a membrane-bound nucleus. Instead, they have a nucleoid region located in the cytoplasm. The DNA in these cells is located in the nucleoid region, which is where replication occurs.  

In both cases, the process of DNA replication involves three main steps – unzipping, elongation, and termination.
