Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

As determined by computer sequence analysis, the average exon length in Arabidopsis thaliana, Oryza sativa, Caenorhabditis elegans , and Homo sapiens genes decreases with an increasing number of introns. In A. thaliana and O. sativa , variations in intron and exon lengths with an increasing number of introns are highly correlated. Linear correlation is observed between the total exon length and the number of introns, while the gene length increases in proportion to the number of introns. In human, the average intron and gene lengths depended on the gene density in DNA.
