Why is it essential that the same restriction enzyme be used to cleave (cut) the DNA of both organisms used to create a transgenic organism? Why is polypeptide synthesis important? What is recombinant DNA? How do restriction enzymes involved in this process?
What does a mutation in the DNA do to the polypeptide? What catalyzes DNA synthesis? What is recombinant DNA technology? What would you need to do to a plasmid vector in order to prepare it to receive the foreign DNA? Your DNA model appeared ladder-like. What is the true shape of a ...
Calmodulin also plays an important role in lipid metabolism by affecting Calcitonin. Calcitonin is a polypeptide hormone that lowers blood Ca2+levels and activates G protein cascades that leads to the generation of cAMP. What type of protein is calmodulin? Calmodulin is alow molecular weight, acidic...
Tissue Polypeptide Antigen (TPA) was originally defined by Bjorklund (1957) from human carcinomas and has been extensively used in the monitoring of cancer. It has been inferred from histochemical data that TPA could be related to cytokeratins (Nathrath et al . 1983). Alignment of the ...

Collagen is a polypeptide which contains a mixture of amino acids like proline and glycine. It makes up 70% of the protein in the skin. Hence, it influences the keratin and its growth. The hair, horns, claws, hooves, and nails contain Keratin, a fibrous structural protein. And brittle ...
ADA exists in both small form (as a monomer) and large form (as a dimer-complex). In its monomeric form, the enzyme is a polypeptide chain folded into an 8-stranded parallel α/β barrel, which surrounds a central deep pocket serving as the active site. In addition to the 8 central ...
