Towards understanding selenocysteine incorporation into bacterial proteins.

abstract：:Mutations of the p53 gene may alter the specific regulatory domains of the protein. We examined the conserved domains III, IV and V by SSCP using PCR primers covering exons 5, 6, 7 and 8 from hairy cell leukemia (HCL), polyps, colorectal and gastric carcinomas. A low rate of p53 mutations was detected in HCL and polyp...
