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.

Они признаны виновными по части 4 статьи 160 УК РФ («Присвоение или растрата в особо крупном размере»). Федоров получил пять лет лишения свободы, а Мялкина — три года. Оба будут отбывать наказание в колонии общего режима. Кроме того, суд оштрафовал фигурантов. Так, бывшего ректора обязали выплатить 500 тысяч рублей, а его зама — 300 тысяч рублей.，详情可参考旺商聊官方下载
