The degenerate primers CK6-5′ and ARK7-3′ (Palumbi, 1996) were initially used to amplify across an intron in the Ark locus. As these primers were not specific, the different bands obtained were cloned ...

In this paper, we use the mitochondrial region cox1 to assess the usefulness of this marker in addressing evolutionary relationships within the tribe Orchideae. Despite the low overall variation ...

Researchers at University of Tsukuba have decoded the nuclear genome of Amorphochlora amoebiformis, a unicellular marine alga ...

We are far from understanding all the rules that govern the process of RNA splicing and defining the sequence information that governs intron definition. In the September 25 Proceedings of the ...

BLOOMINGTON, Ind. -- The sequences of nonsense DNA that interrupt genes could be far more important to the evolution of genomes than previously thought, according to a recent Science report by Indiana ...

The sequences of nonsense DNA that interrupt genes could be far more important to the evolution of genomes than previously thought, according to researchers. Their study of the model organism Daphnia ...

Within multi-exon genes, after introns are removed, the exons must be spliced back together. Splice-enhancer domains (exon sequences near the intron–exon boundary) help to ensure that this happens ...

Plant Systematics and Evolution, Vol. 282, No. 3/4, Special Issue: Molecular evolution and phylogenetic utility of non-coding DNA (October 2009), pp. 201-228 (28 pages) Malpighiales are one of the ...

Scientists have discovered that some tiny segments of RNA thought to be junk instead have a functional role in suppressing production of certain messenger RNAs and appear to help cells respond to ...

A novel type of “jumping gene” may explain why the genomes of complex cells aren’t all equally stuffed with noncoding sequences. All animals, plants, fungi and protists — which collectively make up ...
