Genes come and go
Our recent finding that the Candida albicans RNase III enzyme CaDcr1 is an unusual, multifunctional RNase III coupled with data on the RNase III enzymes from other fungal species prompted us to seek a model that explained the evolution of RNase III's in modern budding yeast species. CaDcr1 has both dicer function (generates small RNA molecules from dsRNA precursors) and Rnt1 function, (catalyze...
متن کاملTransfers and Development Easy Come , Easy Go ?
A central behavioral assumption of economic theory is that income is fungible. Yet, building on the pioneering work by Thaler (1999) recent work by behavioural economists highlights that people code income in different mental accounts, creating a direct link between spending behaviour and income sources, thereby violating the fungibility assumption. This paper examines whether the marginal prop...
متن کاملEasy Come - Easy Go Divisible Cash
Recently, there has been an interest in creating practical anonymous electronic cash with the ability to conduct payments of exact amounts, as is typically the practice in physical payment systems. The most general solution for such payments is to allow electronic coins to be divisible (e.g., each coin can be spent incrementally but total purchases are limited to the monetary value of the coin)...
متن کاملSL trans-splicing: easy come or easy go?
Is spliced-leader (SL) trans-splicing an ancestral eukaryotic characteristic that has been lost in multiple lineages, or did it arise independently in the various phyla in which it occurs? Recent studies have discovered SL trans-splicing in new metazoan phyla, including the chordates. Its discovery in chordates identifies, for the first time, a phylum that clearly contains both trans-splicing a...
متن کاملEvolutionary dynamics of nematode operons: easy come, slow go.
Operons are widespread in prokaryotes, but are uncommon in eukaryotes, except nematode worms, where approximately 15% of genes reside in over 1100 operons in the model organism Caenorhabditis elegans. It is unclear how operons have become abundant in nematode genomes. The "one-way street" hypothesis asserts that once formed by chance, operons are very difficult to break, because the breakage wo...
