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 ...

The human major histocompatibility complex (MHC) class I chain-related gene A (MICA) has a high degree of genetic diversity. Several methods have been used in MICA typing. Recent studies reported ...

The tribe Thomsonieae (Araceae) comprise two genera of palaeotropical herbs: Amorphophallus with approximately 200 species and Pseudodracontium with seven species. A phylogenetic study of the ...

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 ...

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 ...
