Correct. For APEX it is, A protective shell around a virus.
Bacteriophage is a type of virus that infects bacteria. It uses its protein capsid to inject its genetic material into a bacterial cell and replicate. Pilus is a structure found on bacteria that can be used for conjugation, the transfer of genetic material between bacterial cells.
A bacteriophage primarily consists of two main structures: the protein coat, or capsid, which protects its genetic material, and the nucleic acid core, which contains the viral genome (either DNA or RNA). The capsid can have various shapes, including icosahedral or helical forms. Additionally, many bacteriophages have a tail structure that aids in the attachment and injection of their genetic material into host bacterial cells.
Uncoating is not part of the bacteriophage life cycle because bacteriophages do not have an external capsid that needs to be removed to release their genetic material. Instead, bacteriophages inject their genetic material directly into a host bacterial cell.
the parts are: the head or the capsid which contains the plasmid. it has protein subunits called capsomeres. another part is the sheath which contains the viral DNA tail fibers, base pate and pin for attachment to the host's cell.
A bacteriophage virus is composed of a protein capsid that encloses its genetic material, which can either be DNA or RNA. The capsid is made up of protein subunits called capsomeres arranged in a helical or icosahedral structure. Some bacteriophages also have a tail structure used for attaching to and infecting bacterial cells.

The type of virus that infects a bacteria is called a bacteriophage. An example of such a bacteriophage is the T3 bacteriophage.
The part of the bacteriophage that carries the genetic information is the nucleic acid, which can be either DNA or RNA, encapsulated within a protein coat called the capsid. This is significant because the genetic material is essential for the bacteriophage's ability to infect host bacteria, replicate, and produce new phages. Understanding this mechanism is crucial for developing phage therapy as an alternative to antibiotics and for advancing our knowledge of gene transfer and viral behavior.

The protein coat surrounding the nucleic acid of a virus is called the capsid. These are broadly classified according to their structures. Helical (cylindrical) and icosahedral (spherical) are the most common types.
