Hi there!
Cell cycle has 2 phases (i.e M-phase and Inter-phase). Interphase is considered to be the longest phase. Interphase also has G1-phase, S-phase and G2-phase. In cell cycle while moving from M-phase it has two option either to go in G1-phase or G0 phase. It it goes to G0-phase it doesn't go under cell division but if it goes to G1-phase it starts to prepare materials required to replicate or copy DNA. After preparing all the material it goes in S-phase and copies DNA. It doesn't go to G2-phase until it copies DNA perfectly. Then it goes to G2-phase. In this phase it prepares material for replication of other cell organelles.
Therefore, DNA is copied in S-phase.
Hope it helps!

Explanation:
Blood and lymph are the two circulating fluids in the animal body. Blood belongs to the circulation system whereas lymph belongs to the lymphatic system. Blood contains pigments which carry oxygen. Therefore, blood can be found in different colors in different types of organisms. But, lymph is a colorless fluid. Blood is composed of red blood cells, white blood cells, platelets and a fluid called plasma. Lymph is composed of white blood cells and a watery fluid. Both blood and lymph possess a circulatory function as well as an immune function. The main difference between blood and plasma is that blood circulates inside blood vessels whereas lymph circulates inside lymphatic vessels.
