"viral reverse transcriptase to make a DNA copy that is integrated into the host genome and then host RNA polymerase transcribes it. B. host DNA polymerase to replicate their genome and host RNA polymerase to transcribe it. C. viral RNA-dependent RNA polymerase to replicate their genomes and transcribe it. D. use restriction enzymes to replicate and transcribe their genomes."

"Viral reverse transcriptase to make a DNA copy that is integrated into the host genome and then host RNA polymerase transcribes it is a true statement.

Explanation:

The virus is an infectious agent which is not considered living either considered non- living. The virus particles contain the genetic material that determines the trait of a virus in the form of either DNA or RNA.

The virus which contains the RNA replicates themselves by fist converting their RNA into DNA by reverse transcriptase enzyme. Once the DNA is made, the DNA is incorporated in the genome of the host and the machinery of the host performs the replication, transcription and translation.

Thus, the selected option is true.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
