The Hershey-Chase experiment was conducted in 1952 by scientists Alfred Hershey and Martha Chase. They used a bacteriophage, a virus that infects bacteria, to investigate whether genetic material is made of DNA or protein. They labeled the DNA of the bacteriophage with radioactive phosphorus and the protein coat with radioactive sulfur. After infecting the bacteria with the labeled bacteriophages, they found that only the radioactive DNA was transferred into the bacteria, proving that DNA, not protein, is the genetic material. This experiment provided crucial evidence supporting the idea that DNA is the molecule responsible for carrying genetic information. **

The average speed of a racing bike can vary depending on various factors such as the terrain, the skill and fitness level of the rider, and the type of bike being used. However, a well-trained cyclist on a flat road can typically maintain an average speed of 15-20 miles per hour (24-32 kilometers per hour) over a long distance. In a professional race, the average speed can be much higher, often exceeding 25-30 miles per hour (40-48 kilometers per hour). **
