VEGF
VEGF (Vascular Endothelial Growth Factor) is a signaling molecule that binds to receptors on blood vessels. The binding VEGF to the receptors signals the blood vessels to sprout and elongate toward the source of the VEGF. Tumors release VEGF, stimulating the development of their own blood supply thu
Angiogenesis
A tumor consists of cells that are dividing at an abnormally high rate, crowding surrounding healthy cells and competing for resources. Tumor growth typically proceeds in 3 dimensions, pushing out from the surrounding normal tissue and growing to become visible to the naked eye. A tumor must recruit
The Chemical Structure of DNA
DNA's chemical properties can be harnessed for a variety of biotechnology applications.
Translation (advanced detail)
Messenger RNA (mRNA) carries DNA's genetic information to the ribosome, where it is translated into a sequence of amino acids. mRNA is fed into the ribosome, and it is positioned so that it can be read in groups of three letters, known as codons. Each mRNA codon is matched against the transfer RNA m
Autism and the Structure and Function of Synapses
Genes associated with autism affect the structure and function of neuronal synapses.
Development of the Cerebral Cortex
Most of the neurons of the cerebral cortex arise from progenitor cells that undergo repeated cell division.
