The Packaging Mechanism of T4 DNA Involves Cutting of DNA

Question

The packaging mechanism of T4 DNA involves cutting of DNA from
A) linear genetic elements.
B) circular genetic elements.
C) DNA concatemers.
D) its host cells.

Accepted Answer

T4 DNA involves cutting of DNA from DNA concatemers, which are multiple copies of the genome joined end to end. This allows for efficient packaging of the large T4 genome into the viral capsid. The other options, linear genetic elements (A) and circular genetic elements (B), are not involved in the packaging mechanism of T4 DNA. Option D, its host cells, is not accurate as host cell DNA is not involved in T4 DNA packaging.
