DNA segment

DNA segment unwound in order to be read

Our illustration at right, “Gene Regulated Transcription,” appeared in last year’s Medical Illustration SourceBook. Briefly, the illustration shows an unwound segment of DNA made available for use as a blueprint to create, e.g., cell membranes, enzymes, hormones, etc.
I loved the illustration but wasn’t keen on submitting it to the SourceBook– the science behind the illustration is complicated, complex, and far-removed from our everyday experiences.
Now there is a book by Pulitzer Prize winning science reporter / author, Amy Ellis Nutt, that connects the world of genes and DNA to people in the world around us. Becoming Nicole is the true story of two identical twin boys who had obvious differences in gender identification from an early age. Identical twins with identical DNA, but variation in genetic blueprint reading resulted in twins that are no longer identical.
