Consider the following statements regarding the Biosynthesis (Synthesis) phase:

Statement I: "Early proteins" synthesized during viral infection are typically enzymes needed for viral DNA replication and to halt host cell metabolism

Statement II: "Late proteins" include structural components like capsid proteins and tail fibers, which are synthesized after the viral genome has been replicated.

Which of the above statements is/are correct?

#Applied Microbiology

Assertion (A): The time interval between the penetration of the viral DNA and the release of new virions is known as the "Eclipse Period."

Reason (R): During the eclipse period, complete infectious virus particles are not yet detected within the host cell because they are still being assembled from separate components.
