Small particles, with 3 to 200 genes, that cannot replicate without a host cell are called
A)plasmids.
B)recombinant DNAs.
C)bacteria.
D)viruses.
E)tumors.

Question

Quizplus · Accepted Answer

The description fits that of a virus, which requires a host cell to replicate and typically has a genome consisting of a small number of genes. Plasmids are small, circular DNA molecules that can exist independently in bacterial cells and can replicate on their own, but they are not considered viruses. Recombinant DNAs are artificially engineered molecules that contain DNA from different sources, and bacteria are cellular organisms that can replicate on their own. Tumors are abnormal growths of cells and are not related to the description provided.
