摘要: Abstract An extensive analysis of genomic DNA preparations from a number normal and malignant tissues revealed Bgl II site polymorphism the human p53 gene. Approximately 10% gene alleles were found to contain an additional localized in region intron I. This allelic form was also responsible for protein having altered electrophoretic mobility. Molecular cloning sequencing both base-pair change codon 72 causing arginine → proline substitution allele with site. Both variants may occur homozygous state are therefore functional.
