The first step for the policy analyst is to identify the space in which the policy problem exists. This is generally a broad policy space, such as health policy or environmental policy. Next the analyst defines the specific policy issue area.olitical feasibility is a measure of how well a solution to a policy problem, will be accepted by a set of decision makers and the general public.
Preparing a Karyotype. Metaphase cells are required to prepare a standard karyotype, and virtually any population of dividing cells could be used. Blood is easily the most frequently sampled tissue, but at times, karyotypes are prepared from cultured skin fibroblasts or bone marrow cells.None of the leukocytes in blood normally divide, but lymphocytes can readily be induced to proliferate, providing a very accessible source of metaphase cells.lood is easily the most frequently sampled tissue, but at times, karyotypes are prepared from cultured skin fibroblasts or bone marrow cells.

Most living things have chromosomes, or units of genetic information, in their cells. The number and appearance of chromosomes vary among species. A karyotype is the number, size, and shape of chromosomes in an organism. To determine the karyotype of an organism, scientists must follow these steps: 1  Collect a cell from an individual. 2  Induce the cell to divide. 3  Stop cell division in metaphase when chromosomes are easiest to see. 4  Stain the chromosomes to make them visible. 5  View the cell under a microscope.
