Bacteriophage, Set of 8 Models

This set of 8 crystal clear models depicts the destruction of a bacterium by a caliphage T2 virus in phases: 1. the bacterium; 2. phage attaches to the bacterium by its spike; 3. The enzymatic action of the phage's spike dissolves the bacterium wall; 4. phage's DNA enters the bacterium's cytoplasm; 5. phage's DNA self-replicates; 6. the bacterium, following the directions of the phage's DNA, produces viral protein coats; 7. DNA enters the protein coats; 8. lysis of the bacterium. Size of bacterium, 4" wide x 2-1/2" deep x 2- 1/2" high. Key cards included. Overall dimensions of models 1 thru 7 are 5" x 3-1/3" high. Model 8 is 8" x 6-1/2" x 3-1/2" high. Weight 10 lbs. Size of bacterium, 10x6x6cm. Key cards included. Models 1- 7: 13x9x6cm; Model 8: 20x17x9cm. Complete set 5.4kg
