Epigenetic Marker Analysis 3 - Image Index | 20 Ways AI is Advancing Non-Invasive Prenatal Testing DNA Epigenetics: A microscopic view of DNA, with the double helix structure prominently displayed. The DNA molecule is composed of two complementary strands twisted together in a spiral fashion, with each strand made up of nucleotides that are linked by hydrogen bonds. The nucleotides are represented by small blue circles, while the sugar-phosphate backbone is depicted as a series of connected white dots. The image also shows several epigenetic markers, which are chemical modifications to the DNA molecule that can affect gene expression without altering the underlying DNA sequence. These markers are represented by small pink and red circles scattered throughout the image. The background of the image is a subtle gradient of gray tones, which helps to highlight the intricate details of the DNA molecule. Overall, the image provides a fascinating glimpse into the structure and function of DNA at the molecular level.
