How does genetic information flow in an organism? : DNA > RNA > protein Contrast chromosomes and genes. : Genes take part in the production of proteins through the processes of transcription and translation. They are the functional units of heredity. Chromosomes carry genes and take part in cell division during mitosis and meiosis. A dividing eukaryotic cell is treated with a drug that inhibits the molecular motors associated with kinetochores. At which cell cycle stage would it stop? : M (anaphase) What is an example of translational medicine? : A gene product associated with lower cholesterol levels is used to develop a treatment for high cholesterol. A diploid somatic cell from a rat has a total of 42 chromosomes (2n = 42). As in humans, sex chromosomes determine sex: XX in females and XY in males.
