Answer:
Every living organism is made up of cell or cells. Hence, cells are known to be the basic unit and characteristic of life. All organisms need certain characteristics to survive such as air, energy and water. Oxygen is required by almost every living organism to breathe. Carbon dioxide is essential for plants as they will not be able to carry out photosynthesis without it. Nitrogen is also essential for the building of macromolecules like amino acids by the living cells.

Answer: Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.
