Explanation / Answer
1. Escherisia coli and bacteriophages
Hershey and Chase showed that when bacteriophages , which contain DNA and protein, infect bacteria , their DNA enters the host cell but most of their protein does not.
2. DNA helicase
They help to unwind the double helix DNA strands
3. Introns
These are the non-expressable sequence of DNA and hence have no role in transcription of genes.
