EVERYDAY SCIENCE

Detailed explanation-1: -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. DNA replication is an essential process and the basic mechanism is conserved in all organisms.

Detailed explanation-2: -During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes. When mitosis is not regulated correctly, health problems such as cancer can result.

Detailed explanation-3: -Due to the process of DNA replication, each daughter cell gets an equal amount of DNA. The process of DNA replication helps in the inheritance process by transfer of the genetic material from one generation to another. Therefore it is required for the growth, repair, and regeneration of tissues in living organisms.

Detailed explanation-4: -DNA replication results in the duplication of DNA content in the cell, which is essential to maintain genetic continuity in the newly formed cell during cell division. Each cell receives the exact copy of DNA as a parent cell. This is required for growth and maintenance.

Detailed explanation-5: -DNA replication occurs in the nucleus in eukaryotes, whereas in cytoplasm in prokaryotes.
