Video from Osmosis from Elsevier on YouTube

3.1.3 Explain the errors of cell division (non-disjunction, aneuploidy) and the factors that affect cell growth, and relate them to health and disease, including cancer.

Why this video

Explains how meiotic non-disjunction leads to trisomy 21 and illustrates the pathological consequences of autosomal aneuploidy.

Part of this line

Covers part of this objective. It leaves out: It focuses on Down syndrome and does not cover factors regulating cell growth, mitotic non-disjunction, or cancer.

Heads up

The video discusses clinical features, diagnosis, and pathology that go beyond the basic biochemical mechanism of non-disjunction.
