31. The first is the 19 kDa coat or capsid protein ( CP ). 32. This fusion creates a pore through which the viral capsid enters the cell. 33. The major capsid protein is predominantly ?-sheeted. 34. Maturation is submitted by the assembly of bacteriophage DNA and capsids into virions. 35. Capsids are broadly classified according to their structure.36. The capsid contained a single molecule of double stranded DNA of about 50 kilobases. 37. Capsids were assembled from a starting point, the connector and around a scaffold.38. The DNA was cut to size and entered preformed capsids by a headful mechanism. 39. VP1, VP2, and VP3 form the major part of the protein capsid . 40. In some cases, virus-like particles can be formed from capsid proteins.
