Description

Reagent mixing arrangement for chromosome experiments

Technical Field

The utility model relates to the technical field of chromosome experiments, in particular to a reagent mixing device for chromosome experiments.

Background

Chromosomes (chromosomes) are a specific form of DNA that exists in cells during mitosis or meiosis. Within the nucleus, DNA is tightly wrapped around a protein called histone and packaged into a linear structure. When the cell does not divide, the chromosomes are not visible in the nucleus — also under the microscope. However, the DNA constituting the chromosomes becomes more compact during cell division, and the chromosomes are visible under a microscope. Each chromosome has a pinch point called the centromere (point), which divides the chromosome into two parts, the "arms". The short arm is a 'p-arm'; the long arm is a "q-arm". The location of the centromere (dot) on each chromosome provides a unique shape to the chromosome that can be used to help describe the location of a particular gene.
