PPT-Karyotype

A chart of chromosome pairs arranged by length and location of the centromere How are karyotypes made Somatic cells remember these are body cells in metaphase are grown and then dropped onto a slide bursting the nucleus . Erica Martin, advised by Dr. Spilatro. Introduction. Melanoma is a type of skin cancer that is becoming increasingly common. In recent years, rates of increase in melanoma cases among Caucasian have been between 3-7% per year [1] . Additionally, the prevalence of melanoma doubles every 10-20 years [1]. Melanoma is able to spread to other parts of the body, through the process known as metastasis. One method used to study melanoma is the murine B16 melanoma cell line. . Genetics 202. Jon Bernstein.
