**Step-by-Step Text Solution:** 1. **Understanding the Question**: The question states that the discovery of the enzyme Eco R1 led to the awarding of Nobel Prizes to W. Arber, H. Smith, and D. Nathans in 1978. We need to determine if this statement is true or false. 2. **Identifying Eco R1**: Eco R1 is a restriction endonuclease, which is an enzyme that cuts DNA at specific sequences. It is important to note that restriction endonucleases play a crucial role in molecular biology, particularly in genetic engineering. 3. **Understanding Restriction Endonucleases**: These enzymes recognize specific sequences in the DNA, often palindromic sequences, which means the sequence reads the same forwards and backwards. For example, Eco R1 recognizes the sequence G A A T T C and cuts it at specific points. ...
