Recombination is typically thought of as a symmetrical process resulting in large-scale
reciprocal genetic exchanges between homologous chromosomes. Recombination events …

In both the monocot rice and the dicot Arabidopsis, highly expressed genes have more and
longer introns and a larger primary transcript than genes expressed at a low level: higher …

Unraveling the evolutionary forces responsible for variations of neutral substitution patterns
among taxa or along genomes is a major issue for detecting selection within sequences …

Eukaryotic organelle genomes are generally of conserved size and gene content within
phylogenetic groups. However, significant variation in genome structure may occur. Here …

Research into the origins of introns is at a critical juncture in the resolution of theories on the
evolution of early life (which came first, RNA or DNA?), the identity of LUCA (the last …

Gymnosperms represent an ancient lineage that diverged from early spermatophytes during
the Devonian. The long fossil records and low diversity in living species prove their complex …

Chromatin in sperm is different from that in other cells, with most of the genome packaged by
protamines not nucleosomes. Nucleosomes are, however, retained at some genomic sites …

Intronic DNA is a major component of eukaryotic genes and genomes and can be subject to
selective constraint and have functions in gene regulation. Intron size is of particular interest …

Using the two largest collections of Mus musculus and Homo sapiens transcription start sites
(TSSs) determined based on CAGE tags, ditags, full-length cDNAs, and other transcript data …

Background Functional and morphological studies of tandem DNA repeats, that combine
high portion of most genomes, are mostly limited due to the incomplete characterization of …
