Detailed explanation-1: -The new strand is proofread to make sure there are no mistakes in the new DNA sequence. Finally, an enzyme called DNA ligase? seals up the sequence of DNA into two continuous double strands. The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides.

Detailed explanation-2: -DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

Detailed explanation-3: -DNA replication occurs during the S phase (the Synthesis phase) of the cell cycle, before mitosis and cell division. The base pairing rules are crucial for the process of replication. DNA replication occurs when DNA is copied to form an identical molecule of DNA.

Detailed explanation-4: -Both DNA Replication and Transcription involve the generation of a new copy of the DNA in a cell. DNA transcription is involved in replicating the DNA into RNA, while DNA replication makes another copy of DNA. Both processes are involved in the production of new nucleic acids-DNA or RNA.

Detailed explanation-5: -DNA replication occurs in the nucleus in eukaryotic cells and in the nucleoid region of prokaryotic cells. Eukaryotic cells are cells that have a nucleus and membrane bound organelles, such as plant cells and animal cells. Eukaryotic cells contain their DNA in the nucleus, and thus this is where DNA replication occurs.
