Question

In what 3 ways is the replication process of an animal virus different than replication of a bacteriophage?

Answer 1

fog SSRNA + it directly transcribed to proteins vina) -SSRNA ARNA-dependent RNA polymerase replicate it to +SSRNA ** from these pooreman made in case of bacteriophage, after intering the host cell, bera virus synthesis viruse coded endomucleases to degrade the bacterial chromosome and then hijacks the host cell to replicate transcribe and translate the viral components. This is for lyric cycle. For lysogenic cycle, the phage genome integrates into the bacterial enromo- some and becomes part of the host. The phage DNA will also get replicate along with the bacterial chromosome. * For animal virus, the release of the or budding new progeny is through exocytosistbadane The new viral parricies made are released in to extracellular fluid and the host all is not killed 10 resa in the case of bacteriophage, progeny virus is released through host cell lysis,

PEA In animal viruses, ir genetic material is dsDNA, it express theió genes using the normal flow of genetic information from DNA to RNA. to protein.
