Which type of viral capsids are composed of multiple protein types and exhibit nonsymmetrical shapes?
A
Complex capsids
B
Icosahedral capsids
C
Helical capsids
D
Enveloped capsids
Verified step by step guidance1
Understand that viral capsids are protein shells that encase the viral genome, providing protection and aiding in the infection process.
Recall the main types of viral capsid structures: icosahedral, helical, enveloped, and complex capsids, each with distinct shapes and protein compositions.
Recognize that icosahedral capsids are symmetrical and composed of identical protein subunits arranged in a geometric pattern.
Note that helical capsids are also symmetrical, formed by repeating protein units arranged in a helix around the nucleic acid.
Identify that complex capsids differ by being composed of multiple types of proteins and having nonsymmetrical, irregular shapes, often seen in certain bacteriophages.
