उत्तर
DNA was first proven to be the transforming factor in bacterial cells by Avery.
Explanation:
In 1944, Oswald Avery and his colleagues conclusively proved that this transforming principle was DNA. They used specific enzymes to destroy proteins, RNA, and DNA in the bacterial extract; only the destruction of DNA stopped the transformation from occurring, thereby proving it was the hereditary material.
