Abstract

In a method for molecular-biological analysis of genetic material, a genomic DNA or RNA preparation is tested for the presence of mutations. The processed DNA or RNA preparation is contacted with a first set(s) of interconnected solid phase members (5) supporting oligonucleotide primers to bind a defined DNA or RNA fragment that may contain a stable mutation to each solid phase member, and/or with a second set(s) of interconnected solid phase members (5) supporting oligonucleotide primers to bind a defined DNA or RNA fragment that may contain an unstable mutation or several stable mutations to each solid phase member. The solid phase members (5) of the first set(s) are introduced into a matching first set(s) of interconnected receptacles (7) with reaction mixtures for producing products which contain an incorporated marker when a supported DNA or RNA fragment has a mutation. The solid phase members (5) of the second set(s) are introduced into a matching second set(s) of interconnected receptacles (7) containing reaction mixtures for performing sequencing reactions. The contents of the presence of a marker indicating stable mutations is determined from the first set(s) of receptacles, and the sequence for the DNA or RNA fragments is determined from the second set(s) of receptacles. On the bases of these analyses, the genetic status of the genomic DNA or RNA material is determined. A system for performing such analyses is also disclosed.
