(Genome) size matters.
The quotation above has led to the commonly held view that all bacteria will eventually become resistant to any antibiotic given enough time and exposure. However not all bacteria develop resistance to antibiotics at the same rate (and perhaps some species of bacteria may never develop resistance to certain antibiotics). And some bacteria that have been labeled “resistant” are not, in any clini...

متن کاملA Model for Genome Size Evolution
We present a model for genome size evolution that takes into account both local mutations such as small insertions and small deletions, and large chromosomal rearrangements such as duplications and large deletions. We introduce the possibility of undergoing several mutations within one generation. The model, albeit minimalist, reveals a non-trivial spontaneous dynamics of genome size: in the ab...
متن کاملGenome-size evolution in fishes
Fishes possess both the largest and smallest vertebrate genomes, but the evolutionary significance of this variation is unresolved. The present study provides new genome-size estimates for more than 500 species, with a focus on the cartilaginous and ray-finned fishes. These results confirm that genomes are smaller in ray-finned than in cartilaginous fishes, with the exception of polyploids, whi...
متن کاملSize matters: just how big is BIG? Quantifying realistic sample size requirements for human genome epidemiology
Background Despite earlier doubts, a string of recent successes indicates that if sample sizes are large enough, it is possible—both in theory and in practice—to identify and replicate genetic associations with common complex diseases. But human genome epidemiology is expensive and, from a strategic perspective, it is still unclear what ‘large enough’ really means. This question has critical im...
