Answer #1

structure denoted by 2 - Nucleus - controls protein synthesis and contains DNA in chromosomes. It contains the cell's genetic material. They are organized as DNA molecules along with proteins to form chromosomes.

C is denoted by viral envelope and they are derived from portions of host cell membranes and contains viral glycoproteins. It protects the RNA and DNA molecule and evades the recognition of immune system and helps facilitate the entry of virus.

Its a typical lytic cycle of bacteriophage in which 1) attachment-phage attaches to surface of host 2) penetration-viral DNA enters the host cell 3) biosynthesis-phage DNA replicates and phage proteins are made 4) maturation-new phage particles are assembled 5)lysis- cell lyses releasing the newly made phages.

Number 3 represents free ribosomes on ER. Its functions are to synthesis proteins directed by m-RNA. And help produce proteins with many different functions in body seen in ER(Rough ER)
