These results indicate that the concept of most recent common ancestry, which is essential for assessing relative relatedness among taxa, is difficult for college biology students to apply to evolutionary relationships represented diagrammatically in a cladogram.
The establishment of a chronology of landscape-forming events in lowland and mid-altitude Tasmania, essential for assessing the relative importance of climatic and human influences on erosion, and for assessing present erosion risk, has been limited by the small number of ages obtained and limitations of dating methods.
While insulin and Akt signaling have been found previously to be essential for adipogenesis, the relative importance of their many downstream branches have not been defined.
Further studies, particularly genome-wide association studies and inclusion of paternal samples will be essential for elucidating the relative contributions of paternal and fetal genotypes to the risk of PTB.
Residues clustering in the active site region (Pro121, Gly124, Ala127, Asn175, Leu179-Gly180, Ser201-Gly206, Gly206, Asp215-Trp216 (CifPl numbering)) are expected to be either essential for maintaining the relative positions of the triad residues or be involved in substrate binding.
Disparity is essential for judgments about relative depth [ 17] and for performance at near distances [ 18].
Thus, establishing a mammalian cell line that lacks Lig1 would be essential for clarifying the relative priority of the three ligases in various DNA transactions.
Although not all residues in a SLiM shorter than 10 amino acids are essential for interaction, their relative conservation is usually strong enough to be detected.
Such mice will also be essential for dissecting out relative contributions of striatal and cerebellar dysfunction to motor-skill learning deficits associated with Foxp2 disruption.
Such insights are essential for inheriting properties between relatives to cope with the huge dearth in experimental annotations.
