Explanation / Answer
A)1.Capsids protect the cell Attachment sites to the host cell,helps determine the shape and size
2.Envelope is a protein containing lipid membrane that surrounds the capsid in some viruses
3.Nucleic acid can be either DNA RNA or never both. can be single or double linear or circular. determines the size. virus with ss strand usually small.
B)1. Endocytic pathway: Enveloped animal viruses enter the host cell by Endocytic pathway engulfying the virus entry via endosome lowers the ph and exposure to proteases which are needed to open viral capsid and release a genetic material inside.
2. Membrane fusion or Hemifusion: The cell membrane is punctured and fusion with the host cell viral envelope blendes the host cell membrane and releasing its content in to the cell.
3. Viral penetration: The virus is simply attching the host surface via receptors and its central sheath pierces the cell membrane and the phage containing genome is injected in the host cell cytoplasm from its head capsid.
C) The amount and arrangements of proteins and nucleic acid of viruses determine the size and shape.The nucleic acid protein assembled in to a structure called nucleoproteins or nucleocapsids based on this viruses are 2 kinds Rods or Filaments,as their genetic information is combined with dsDNA and combine both filamentous and polygonal shapes.Nucleid acid that encodes the genetic information for the synthesis of proteins,a virus can be Icosohedral, enveloped, and complex or helical in shape.so Girls genetic code doesnt determines the shape.
