Calreticulin, a protein which binds to misfolded proteins and prevents them from being exported from the endoplasmic reticulum to the Golgi apparatus. 3d rendering.
Aligned amino acid sequences of various individuals. The amino acids were derived from their three bases in the genetic code and seen in a DNA sequence. This type of alignment is useful in determining the relatedness of individuals. In this case the sequences were derived from the ribosomal genes of a somewhat obscure fungus not known to be of any commercial, industrial or other value.
