Sentences with phrase «dna sequence comparisons»

For example, large - scale taxonomic DNA sequence comparisons have established more rigorous relationship trees and taxonomic distances for the large and diverse class Aves (birds) and the phylum Arthropoda.

Other theories hold that the prokaryotes that gave rise to early eukaryotes were probably from the Domain Archaea, both because of several key characteristics and because DNA sequence comparison suggest that archaeans are more closely related to the eukaryotes than are eubacteria.

A human - chimp comparison revealed some 35 million mutations in the single units of the overall sequence and also found about 5 million additions to or subtractions from the genome involving chunks of DNA sequence.

I marveled at a chart that showed a diagram of the tree of life, where relationships between different mammalian species were figured out solely by comparison of their DNA sequences, providing powerful support for Darwin's idea of descent from a common ancestor with natural selection operating on randomly occurring variations.

The Human Genome Project, which sequenced the 3 billion pairs of nucleotide bases in human DNA, was a piece of cake in comparison: Epigenetic markers and patterns are different in every tissue type in the human body and also change over time.

He also recommends performing standard bulk - cell sequencing on a portion of the sample, to provide a basis for comparison with the single - cell DNA data.

Furthermore, they dated the origin of the species using evolutionary trees calculated from DNA sequences in comparison to the uplifting history of the Himalaya - Tibetan mountain system.

Sequencing of maternally inherited mitochondrial DNA allowed comparison between the relative rates of evolution, which suggested that the coalescence, or origin, of the human Y chromosome and mitochondria both occurred approximately 120 thousand years ago.

The chimp genome sequence, which consists of 2.8 billion pairs of DNA letters, will not only tell us much about chimps but a comparison with the human genome will also teach us a great deal about ourselves.

Bilde thought the velvet spider's genome would hold clues to the animal's social behavior and its odd mix of resilience and fragility, so her team and the Chinese sequencing giant BGI set out to sequence its DNA and, for comparison, that of a tarantula.

DNA sequencing of the ladybird's protein - coding genes revealed roughly 50 that help manufacture antimicrobial peptides, compared with 16 such genes identified in the red flour beetle, which the researchers examined for comparison.

Now, using new data collected samples of ancient, carbonized rice, a team of Japanese and Chinese scientists have successfully determined DNA sequences to make the first comparisons between modern and ancient rice.

These sequences in our DNA are often situated far away from the actual genes they regulate, in comparison to so called promoter regions, which traditionally have been considered to control most of the gene activity.

Scientists have produced the first comparison of DNA sequences between Przewalski's horse and the domestic horse.

Simply determining the DNA sequence of the genome would be sufficient for comparison with the genomes of other species to identify similarities between genes or protein domains among species.

The comparison of sequence data was possible because in recent years thousands of DNA sequences for mosquito genes (or fragments of genes) have been deposited in computer databases.

In our comparison, we did not consider practical parameters such as the required amount of DNA input, sequencing costs, or time required to complete a whole genome sequencing run (Table S1).
