Answer:
They use host cell machinery to produce new copies of their genome.
Explanation:
DNA viruses, which are similar to cells, directly employ cellular machinery to perform their process of replication, transcription of their genes, and DNA repair, that is, they use a host cell to make new copies of their genome. Because of this, some viruses have a large genome, such as herpesviruses, which make their own genes and become somewhat more independent of cell metabolism. DNA molecules are found in two forms: linear and circular. Viruses of the polyomaviridae family have small genomes and circular DNA, while herpesviruses have linear dsDNA genomes. Viruses that have single strand genomes do not allow DNA repair.
Sensory Neurons and Motor Neurons. Motor neurons would make you withdraw your hand spontaneously when it touches something hot.
Chloroplasts. They are only in green plant cells, so, unless you are a green plant, humans and flatworms would not contain them.
