[The restrictase analysis of human DNA as a method for determining genetic sex in forensic biological expertise]. / Restriktaznyi analiz DNK cheloveka kak metod opredeleniia geneticheskogo pola v sudebno-biologicheskoi ékspetize.

In this article phenomena related to sex heteromorphism of restrictase hydrolysates of DNA, isolated from objects of expert analysis was recommended for use. The performed investigations allow one to work out the system of discriminating sex of biological objects, based on restrictase analysis of human DNA and on registration of sex-specific restrictase fragments. Possibilities of method and its value for gene-identification expertise were illustrated using certain cases from expert practice.

[The primary investigation of material evidence and the evaluation of its suitability for expert biological identification by genomic "dactyloscopy"]. / Pervichnoe issledovanie veshchestvennykh dokazatel'stv i otsenka ikh prigodnosti dlia biologicheskoi identifikatsionnoi ékspertizy metodom genomnoi "daktiloskopii".

Use of DNA "fingerprinting" method for biological analysis of material evidences exhibit new potentials for making concrete expert conclusions. But such expertise is time consuming and difficult to perform that's why it is important to evaluate fitness of expert material for DNA fingerprinting at early stages of object investigation. Method of preliminary treatment of objects sent for DNA fingerprint expertise in case of sexual assault is suggested and tested. This method allows one to evaluate objects easily from the standpoint of possibility to perform such investigation.

[Genomic "dactyloscopy" in the expertise of disputed paternity and the determination of biological relationship]. / Genomnaia "daktiloskopiia" v ékspertize spornogo ottsovstva i opredeleniia biologicheskogo rodstva.

Genome "dactyloscopy" (DNA fingerprinting) is a principally new way of personal identification based on analysis of human genetic material (DNA); the difference in DNA structure of different subjects is the scientific basis of this method. This ensures opportunity to estimate biological relationship of persons positively. The authors were the first to demonstrate using certain expert material the adequacy and potentials of DNA fingerprinting by M 13 probe for medicolegal expert practice in most complicated cases of relationship determination requiring positive identification of paternity and maternity.
