Centromeres are chromosomal loci that direct segregation of the genome during cell division. The histone H3 variant CENP-A (also known as CenH3) defines centromeres in monocentric organisms, which confine centromere activity to a discrete chromosomal region, and holocentric organisms, which distribute centromere activity along the chromosome length.

Lower jaw development is a complex process in which multiple signaling cascades establish a proximal-distal organization. These cascades are regulated both spatially and temporally and are constantly refined through both induction of normal signals and inhibition of inappropriate signals. The connective tissue of the tongue arises from cranial neural crest(More)
Three sources of observation relevant to the measurement of individual differences in emotional and esthetic expressiveness were employed to study their heritability by application to a sample of some 60 pairs of young adult like-sexed twins, approximately evenly divided between male and female and MZ and DZ pairs. The sources of observation were objective(More)
