Revise structure and replication of DNA for your Higher Human Biology exam with Bitesize Scotland interactive practice quizzes covering feedback and common errors.

A more fundamental understanding of DNA structure and its relationship to genetic sequences, researchers say, helps set the stage for applied advances in biology, biomedicine, genetic engineering ...

For the first time, scientists have detected a DNA structure inside living human cells that looks more like a four-stranded knot than the elegant double helix we learned about in school.

DNA, the hereditary material in living organisms, encodes genetic instructions for development and function. We explore its structure, replication, and role in biotechnology.

The results of this collaborative project overturn some conventional wisdom about how the DNA repair process works.

DNA is a central topic in biology courses because it is crucial to an understanding of modern genetics. Many instructors introduce the topic by means of a sanitized retelling of the history of the ...
