Why do many scientists study yeast cells to understand human genetics?
Character B says that the genes work in almost the same way, which is accurate. Although yeast cells are members of the Kingdom Fungi and are single-celled organisms, they are eukaryotic cells that function very much the way that single human cells function. The building blocks for DNA are the same, and the processes of transcription and translation are nearly identical, but they produce different proteins than humans do. Because of the similarities, scientists can inexpensively and easily run experiments with millions of yeast cells in a very short amount of time. Similar experiments with humans would be impossible. They also don’t complain when a scientist tells them to do something. Answer A is wrong because if yeast genes were identical to human genes, yeast cells would not be yeast cells, they would be human! However, there are many genes related to basic cellular processes (such as cellular respiration) that are VERY similar. Answer C is false because the genes do work in the sam
