The consortium of scientists that examined the mouse genome found 25 cases in which humans have a single gene and the mouse a cluster of related genes.
The researchers, in experiments with Arabidopsis, a weed with a relatively small and simple genome, found that mutant plants without the protein could not handle too much sun, developing bleached, dead spots.
In the mid 1990s, he worked out a quick-fire way of analysing the full complement of DNA, the genome, found in bacteria.
Their analysis of the architecture of the virus's genome found that its RNA structure plays a key role in its infection cycle.
A14 Variations in the Genome Scientists said a study of the variability in the human genome found that each human gene may come in 12 different versions on average, a finding that cast doubt on an effort to mine the genome for the genetic basis of common human diseases.
In all dinoflagellate species studied to date, the plastid genome is highly reduced, with many genes normally found in the plastid genome found instead encoded by the nucleus.
But scientists deciphering the human genome found, to their surprise, that these protein-coding genes took up less than 3% of the genome.
Sequencing of the tammar genome found "innovation in reproductive and lactational genes, rapid evolution of germ cell genes, and incomplete, locus-specific X inactivation".
Analysis of the C. savignyi genome found little evidence to support an elevated mutation rate, but rather points to a large population size contributing to the polymorphism level.
Although sensitive BLAST searches of the genome found a few short DNA fragments (27 and 33 nt in length) with ≥93% similarity to cox2, these could easily represent spurious matches.
Even more peculiar, instead of the standard circular plastid genome found in other photosynthetic eukaryotes, the peridinin-containing dinoflagellates display multiple replicating minicircles carrying one or two genes [19].
