7.8: Virus Structures - Biology LibreTexts
Helical capsids are made up of a single type of protein subunit stacked around a central axis to form a helical structure. The helix may have a hollow center, which makes it look like a hollow tube. This arrangement results in rod-shaped or filamentous virions. These virions can be anything from short and very rigid, to long and very flexible. More Information

Double Helix - The Definitive Guide | Biology Dictionary
Double helix is the term used to describe the shape of our hereditary molecule, DNA. This instantly recognizable structure consists of two strands of DNA twisted around one another and connected in the center by hydrogen bonding. The hydrogen bonds form between nucleotides – the repeating unit of DNA and the language of the genetic code. More Information

Fundamental Properties and Types of Helical Polypeptides ...
Among the diverse shapes that can be assumed by polypeptide chains is a helical shape; in fact, helically arranged polypeptides are fundamental to the shape of many fibrous and most globular proteins. To understand the properties of helical polypeptides, let us first consider the general properties of a geometric helix. More Information
