Keyword analysis and complexity of genes. Using Google Scholar, a full-text search of scientific articles was performed for the keywords “intron,” “alternative splicing,” and “intergenic transcription.” Slopes of curves indicate that in recent years the frequency of mentioning of terms relating to the complexity of a gene has increased. (The Google Scholar search was limited to articles in the following subject areas: “Biology, Life Sciences, and Environmental Science;” “Chemistry and Materials Science;” “Medicine, Pharmacology, and Veterinary Science.”)
