Final answer:
The main goal of DNA replication is to make identical copies of DNA to ensure that each new cell has the same genetic information as the parent cell.
Step-by-step explanation:
The main goal of DNA replication is to make identical copies of DNA. This is crucial because when a cell divides during mitosis, each new 'daughter' cell needs to have the exact same genetic information as the parent cell to function properly. The genetic information is in the sequence of nucleotides in the DNA, which codes for everything a cell does, including making proteins. However, the function of DNA replication is not to code for proteins, transport materials outside of the nucleus, or provide energy for the cell. Those are separate processes. Coding for proteins is related to the processes of transcription and translation, while DNA replication solely focuses on copying the DNA to ensure genetic consistency among cells.
