Small Bacteriophage Biology Model

New version! V2 Changes:

Changed the position of the tail fibers to the base plate (more accurate depiction).

Made spikes more defined (V1 had a little bit to small spikes)

Better adhesion

Description:

This model is a representation of a bacteriophage, a fascinating virus that specifically targets bacteria. I've tried to capture the key features of the phage while keeping the design both accurate and relatively simplistic.

The head (capsid) is where the phage stores its genetic material. The part is prominently featured in relation to its importance. Just below the head, there's the neck, which acts as a channel for DNA during infection, and below that is the collar, which helps stabilize the structure. The sheath spiral contracts during the infection process to drive the tail tube into the bacteria.

At the base, the tail fibers extend outward, designed to help the phage attach to a bacterial cell. The base plate serves as the anchor point, where the small spike-like parts help the phage attach and inject the DNA into the host.

In a small nod to the broader context, this bacteriophage model also relates to a fascinating area of genome editing—the modern CRISPR-Cas system, where bacteriophages have played a central role.

I hope this model serves as a useful tool for anyone looking to explore the world of different kinds of viruses and their role in biology. Oh and if you are interested in learning more about CRISPR, I recommend this video by TED-Ed. :)

Good to know:

If printing with silk filament, be a little bit carefull when removing supports around the tail fibers (legs). :)

Also if silk PLA, don't drop it (I tested)…
