Different populations may have different characteristic frequencies, What carry the instructions to manufacture proteins, a cell's use of DNA information to manufacture specific proteins, a site in a genome that varies in 1 percent or more of a population, a cell that upon division replaces its own number and also gives rise to cells that differentiate into one or more specialized types, relating to or being an organism whose genome has been altered by the transfer of a gene or genes from another species or breed, provided a more lasting cure by replacing the instructions from producing the protein, the process by which cells or tissues undergo a change toward a more specialized form or function, the process of analyzing DNA samples to detect the presence of a gene or genes associated with an inherited disorder, a diagram used to follow inheritance of a trait in a family. The key difference between symmetric and asymmetric karyotype is that symmetric karyotype shows a smaller difference between the smallest and largest chromosomes in the set while asymmetric karyotype shows a larger difference between the smallest and largest chromosomes in the set.
