Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where does DNA replication occur in eukaryotic cells?
A
The nucleus
B
The cytoplasm
C
Ribosomes
D
Mitochondria
Explanation: 

Detailed explanation-1: -DNA is found inside the nucleus of eukaryotes. Inside the nucleus, DNA replication occurs. During the Synthesis stage of the Interphase, this DNA replication takes place.

Detailed explanation-2: -Eukaryotic DNA replication requires multiple replication forks, while prokaryotic replication uses a single origin to rapidly replicate the entire genome. DNA replication always occurs in the nucleus. Eukaryotic DNA replication involves more polymerases than prokaryotic replication.

Detailed explanation-3: -DNA replication in eukaryotes occurs in the nucleus of eukaryotes. DNA replication in eukaryotes is also different due to the fact that DNA is linear compared to circular in prokaryotes.

Detailed explanation-4: -By housing the cell’s genome, the nucleus serves both as the repository of genetic information and as the cell’s control center. DNA replication, transcription, and RNA processing all take place within the nucleus, with only the final stage of gene expression (translation) localized to the cytoplasm.

Detailed explanation-5: -Cells must replicate their DNA before they can divide. This ensures that each daughter cell gets a copy of the genome, and therefore, successful inheritance of genetic traits.
