T4 protein and T4 DNA will be in the experimentally constructed bacteriophage composed of the T2 phage protein coat and T4 phage DNA.
Explanation:
The virus infecting bacteria are called as bacteriophage. The virus overtakes the machinery of the host bacterium, shed its protein coat and replicates, in the ends lyses to produce many viruses.
The experimentally constructed phage will have DNA and protein coat same as phage because protein coat is translated from the gene present in viral genome.
In lytic or lysogenic cycle the virus after replicating forms protein coat to protect itself
In the transcription process of virus, the components for viral assembly is synthesized and ultimately translated. The virion assembly takes place. Thus, the protein coat and DNA will be of same phage.
