Sequencing

A visual walkthrough from sample to variant interpretation.

This sample teaches NGS as a workflow, not as a vocabulary list.

NGS sample lesson cover

Fig. 01 · 02 / 06Workflow overview

One sequencer.
Many reads in parallel.

The educational point is simple: instead of reading one region at a time, NGS generates many short reads simultaneously. The learner follows the chain from sample to clinical meaning.

Before the machine reads:
build a library.

Library preparation turns extracted DNA into fragments the sequencer can read. Each step changes the sample in a specific way.

01 Extract

Isolate DNA from the clinical sample and prepare it for downstream processing.

02 Fragment

Break long DNA into short pieces so millions of reads can be generated in parallel.

03 Add adapters

Add molecular handles so fragments can attach, cluster, and be assigned back to a sample.

Reading the visual

The sample uses
real slide visuals.

Instead of generic filler art, this version uses the actual NGS sample visuals: the cover, the workflow slide, and the key concepts slide. That keeps the experience coherent.

The workflow only matters if it reaches
interpretation.

A strong teaching sample should show both the workflow and the conceptual vocabulary learners need: reads, coverage, alignment, and variant.

NGS is not a single machine.
It is a sequence of decisions.

That is the learning frame this sample is designed to make visible.
