Why genes overlap in viruses
The genomes of most virus species have overlapping genes--two or more proteins coded for by the same nucleotide sequence. Several explanations have been proposed for the evolution of this phenomenon, and we test these by comparing the amount of gene overlap in all known virus species. We conclude that gene overlap is unlikely to have evolved as a way of compressing the genome in response to the...
متن کاملViruses, Genes, and Cells1
The intimate relationships of viruses and genes have been proper subjects of speculation for many years. More recently, genetic studies, especially on bacteriophages and bacteria have given concrete substance to some of these speculations. For this occasion a brief didactic review of some relevant experimental findings may be appropriate. The support that they can give to concept and methodolog...
متن کاملWhy genes aren't destiny.
The remote, snow-swept expanses of northern Sweden are an unlikely place to begin a story about cutting-edge genetic science. The kingdom's northernmost county, Norrbotten, is nearly free of human life; an average of just six people live in each square mile. And yet this tiny population can reveal a lot about how genes work in our everyday lives. Norrbotten is so isolated that in the 19th centu...
متن کاملSleep Overlap Syndrome
Overlap syndrome, which is known as the coexistence of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA), was first defined by Flenley. Although it can refer to concomitant occurrence of any of the pulmonary diseases and OSA, overlap syndrome is commonly considered as the coexistence of OSA and COPD. This disease has unique adverse health consequences distinct from ...
متن کاملHow Overlap Determines the Macronuclear Genes in Ciliates
Formal models for gene assembly in ciliates have been developed, in particular the string pointer reduction system (SPRS) and the graph pointer reduction system (GPRS). The reduction graph is a valuable tool within the SPRS, revealing much information about how gene assembly is performed for a given gene. The GPRS is more abstract than the SPRS and not all information present in the SPRS is ret...
