Even fairly deep sequencing of randomly selected cDNA clones fails to elucidate the structures of the 20–40% of genes in a typical eukaryotic genome that are expressed only at low levels or ...

Additionally, genomic analyses of modern eukaryotes indicate that their ancestors likely acquired genes from multiple sources, not just from the engulfed bacteria that became mitochondria. Lateral ...

Differentiate between a gene and an allele. Diagram a typical eukaryotic gene and indicate the locations of (a) regions that are genic but are not coding, (b) regions that are transcribed but not ...

An international collaboration has published groundbreaking research, shedding light on the most significant increase in complexity in the history of life's evolution on Earth: the origin of the ...

This process has been an important factor in eukaryotic evolution, yet the number and timing of these events remains unresolved. One of the main results of secondary endosymbiosis has been the ...

The diagram in Figure 2 shows a typical chromatin fiber ... states of transcriptional control and the ability of eukaryotic cells to turn genes on and off as needed. This complexity provides ...

Genetic studies have made it clear that eukaryotic horizontal gene transfer can and does happen. Exactly how, though, remains speculative. Christie is a seasoned science journalist and cell and ...

the proteins decouple from the multiplicative process of gene growth, and the average protein length stabilizes after the onset of the eukaryotic cell at about 500 amino acids in a clear threshold ...
