Cytogeneticists study cellular processes, with a focus on chromosomes and genetic abnormalities. They take cell samples to aid in diagnosis and research, and use techniques such as karyotyping to study chromosomes. Their work has contributed to scientific discoveries and medical advancements. A four-year undergraduate science degree is required for this field.
A cytogeneticist is concerned with cellular processes within the human body. The genetic portions of cells – or chromosomes – are of particular interest to experts in this field. Thus, hereditary diseases and abnormalities are an important area of study in this field. Cytogeneticists usually take samples of cells from tissues or fluids with the aim of identifying chromosomal functions or aiding in the diagnosis of disease. People looking for a job combining science and medicine can find a fit in cytogenetics, provided they are willing to pursue a four-year undergraduate science degree.
Individuals in this field must be proficient in handling cells under a microscope, as study and research are vital components of cytogenetics. In a laboratory setting, the cytogeneticist can prepare cell cultures, study cell division processes such as mitosis, and investigate small variations and mutations between different cells. Screening for illnesses ranging from cancer to mental illness is common. The work of cytogeneticists can also be important in generating new techniques for performing these complex processes. They could even manipulate cellular structures for the purposes of gene recombination and gene therapy.
Another area of focus for the cytogeneticist is chromosome identification, or chromosome banding. Various techniques such as quinacrine bands and giemsa bands are used to color and study chromosomes. This analysis is known as karyotyping. The cytogeneticist looks for similarities and differences in the structures of various chromosomes. Cells for study can be obtained from various body fluids or tissues.
Cytogenetics has been the centerpiece of many major scientific discoveries. Pioneering work in cellular studies has been used as evidence for natural selection – or “survival of the fittest” – in evolutionary theories. The discovery that deoxyribonucleic acid (DNA) and parts of the chromosome could change and move within a cell led to a Nobel Prize in the 1980s. Cytogeneticists were also at the forefront of advances in stem cell practices and cloning .
Perhaps the most enduring legacy of cytogenetics is its contribution to the field of medicine. The research provided much-needed information about genetic abnormalities such as those responsible for Down syndrome and Klinefelter syndrome. In addition, the cytogeneticist’s work discovered genetic factors for a variety of diseases ranging from anemia to some types of cancer. On a day-to-day basis, cytogeneticists can help make a variety of diagnoses in patients.
In addition to independent work and medical projects, research contributions to the general field are an important role for the cytogeneticist. To ensure scientific integrity and make the results more easily accessible to colleagues, a cytogeneticist will routinely make a written record of all data and generate reports from these data. If the work is particularly noteworthy, researchers can submit their findings to scientific journals.
