The term epi means above. It is a Greek prefix. Also defined as above the DNA base sequence]]> 2023-02-22 22:18:10 UTC https://padlet.com/kiaraaragon06/i9freqc3fchqttsc/wish/2491781936 kiaraaragon06 https://padlet.com/kiaraaragon06/i9freqc3fchqttsc/wish/2491791899 Epigenetics is a field of study focused on DNA changes that do not involve alterations in the underlying sequence.]]> 2023-02-22 22:34:27 UTC https://padlet.com/kiaraaragon06/i9freqc3fchqttsc/wish/2491791899 kiaraaragon06 https://padlet.com/kiaraaragon06/i9freqc3fchqttsc/wish/2491794576 The letters in DNA and the proteins that interact with DNA can have chemical modifications that change the level at which genes are turned on and off. Certain epigenetic modifications can be passed from the parent cell to the daughter cell during cell division or from one generation to the next. The set of all epigenetic changes in a genome is called the epigenome.]]> 2023-02-22 22:39:02 UTC https://padlet.com/kiaraaragon06/i9freqc3fchqttsc/wish/2491794576 kiaraaragon06 https://padlet.com/kiaraaragon06/i9freqc3fchqttsc/wish/2491799974 DNA methylation is altered in cancer so if we know what the normal methylation pattern is and then look at the methylation pattern in a tumor we could see what changes were taking place and which genes were affected.]]> 2023-02-22 22:47:37 UTC https://padlet.com/kiaraaragon06/i9freqc3fchqttsc/wish/2491799974 kiaraaragon06 https://padlet.com/kiaraaragon06/i9freqc3fchqttsc/wish/2491803021 The promise of epigenetics is that it tells us about the cell, it's a way of defining the cell that is different than simply looking at gene expression levels. Any type of cell we look at has specialized epigenetic patterns.]]> 2023-02-22 22:52:40 UTC https://padlet.com/kiaraaragon06/i9freqc3fchqttsc/wish/2491803021
