TY - JOUR. T1 - Developmental genetics and early hominid craniodental evolution. AU - McCollum, M A. AU - Sharpe, P T. PY - 2001. Y1 - 2001. N2 - Although features of the dentition figure prominently in discussions of early hominid phylogeny, remarkably little is known of the developmental basis of the variations in occlusal morphology and dental proportions that are observed among taxa.

A segmented body plan is fundamental to all vertebrate species and this bestows both rigidity and flexibility on the body. Segmentation is initiated through the process of somitogenesis. This article aims to provide a broad and balanced cross-species overview of somitogenesis and to highlight the key molecular and cellular events involved in each stage of segmentation. We highlight where our.

Thus, models and hypotheses about pigment pattern formation derived from zebrafish can now be tested in other Danio species. These studies will lay the foundation to understand not only the genetic basis of colour pattern variation between Danio species, but also the evolution of colour patterns in other vertebrates.

One of the main questions in the use of genome editing tools is their specificity and the degree of possible off-target events. The cover shows two of the protein scaffolds commonly used for this purpose, TALE and Cas9, targeting a DNA site for the generation of specific cleavage.

A histone modification is a covalent post-translational modification (PTM) to histone proteins which includes methylation, phosphorylation, acetylation, ubiquitylation, and sumoylation. The PTMs made to histones can impact gene expression by altering chromatin structure or recruiting histone modifiers. Histone proteins act to package DNA, which wraps around the eight histones, into chromosomes.

Our mission is to pursue scientific research without boundaries. We want the research we produce to be open, accessible and reproducible. The main outputs of our research are new ideas, knowledge and techniques, which we publish as peer-reviewed research publications.

Journal description. BioEssays is a review-and-discussion journal publishing news reviews and commentaries in contemporary biology that have a molecular genetic cellular or physiological dimension.

The primitive streak is a structure that forms in the blastula during the early stages of avian, reptilian and mammalian embryonic development.It forms on the dorsal (back) face of the developing embryo, toward the caudal or posterior end. The presence of the primitive streak will establish bilateral symmetry, determine the site of gastrulation and initiate germ layer formation.

This suggests that the contact force contributes to the formation of cellular bridges and, consequently, to the formation of a large-scale multicellular structure. In our experiments, HeLa cells formed a network-like structure on a thick Matrigel layer in a cell-density-dependent manner.
