DNA is often called the blueprint of life, but what does that really mean? Elizabeth Worthey, Ph.D., associate professor, Department of Genetics in the Heersink School of Medicine, explains everything ...
All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in ...
A study has traced thousands of conserved regulatory elements back 300 million years, revealing deep principles of plant ...
Scientists from the University of Colombia have found an ancient "ghost" DNA genome that existed in South America over 6,000 ...
How do you define biosecurity in the context of DNA? Peccoud: An internet search for biosecurity will return stories about security measures aimed at preventing pests or infectious agents from ...
DNA is often compared to a written language. The metaphor leaps out: Like letters of the alphabet, molecules (the nucleotide bases A, T, C and G, for adenine, thymine, cytosine and guanine) are ...
While tools like CRISPR have blown the field of genome hacking wide open, being able to predict what will happen when you tinker with the code underlying the living things on our planet is still ...
