Natural selection tends to ensure that vital DNA sequences do not accumulate mutations that could interfere with their function.
Examples of two IS-dense intergenic clusters in the SOPE genome are depicted in figure 3. We previously rationalized the clustering of IS elements on the basis that it might be favored by natural selection to avoid the interruption of vital genic sequences (Clayton et al. 2012).
These same chemicals were vital in the sequencing of the human genome, a task accomplished by PE subsidiary, Celera Genomics cra.
L1 promoters and other functional sequences vital to L1 retrotransposition accumulate disruptive mutations as a function of time.
Mechanisms that inhibit HR between divergent sequences while permitting recombination between identical sequences are vital as they enable repair without risking genome re-arrangement.
Investigators have now retrieved the TU-154's cockpit voice recorder and the flight data recorder, which are expected to provide vital information about the sequence of events leading up to the crash.
The HCV-IRES sequence is vital for both protein translation and genome replication and serves as a potential target for anti-HCV therapy.
However, proper planning for the form reuse schemes in the design as well as the construction phases of a building, including resource allocations (modular form sets, cranes, workers, etc)., and the construction sequence, is vital for ensuring a successful use of modular formwork systems.
These essential genes can be presumed to be vital for organism survival, sequence variants in which may lead to lethality.
