Agar was first introduced into the laboratory in 1881. Since then, microbiologists have depended on agar to create strong jellies. When microorganisms are streaked or plated onto this jellied surface and incubated, individual cells multiply into distinct colonies that scientists can easily observe, select, and propagate for further experiments. Many of the most important findings in biological research of the last 150 years or so — including the discovery of the CRISPR/Cas9 gene-editing tool — have been enabled by agar.4 Agarose, a derivative of agar, is also essential in molecular biology techniques like gel electrophoresis, where its porous gel matrix separates DNA fragments by size, enabling researchers to analyze and isolate specific genetic sequences.
While Jenkins and Sunday make for a fun old blood-new guard duo, their findings rarely reveal something that flashbacks haven't already made abundantly clear. The flashbacks themselves are primarily motivated through an interrogation of Clark, who does himself — and the audience! — no favors by staying awkwardly silent at inopportune moments. Are you trying your best to look guilty, Clark, or is DTF St. Louis just withholding information so it can justify its murder hook for another few episodes?
