DNA
It's unlikely that Avery's team conducted DNA experiments in 1944, as DNA research didn't really begin until the 1950s. Avery did pioneer important work in genetics and DNA in the 1940s, particularly related to the transforming principle in bacteria, which later laid the foundation for understanding DNA's role in heredity.
The transforming principle contains DNA molecules. These molecules were identified by scientists Avery, MacLeod, and McCarty in 1944 as the substance responsible for the transfer of genetic information in bacterial cells.
DNA has a role in defining characteristics of the subject which it is taken from.
It is the sugar in DNA
The principle molecule that carries out the instructions coded in DNA is messenger RNA (mRNA). It serves as a template for protein synthesis by carrying genetic information from DNA in the nucleus to the ribosomes in the cytoplasm where proteins are assembled.
The role integrase plays in HIV is that it fuses viral DNA with host DNA.
