CYTOGENETICAL, BIOCHEMICAL AND MOLECULAR IDENTIFICATION OF SOME COMMON EGYPTIAN RODENTS OF THE FAMILY MURIDAE

Abstract

The aim of the work Cytogenetical, biochemical and molecular identification of some common Egyptian rodents of the family Muridae.The species under study are ) Acomys cahirinus –Rattus rattus-Rattus norvegicus - Albino Rattus norvegicus – Mus musculus- Albino Mus musculus- Gerbillus gerbillus- Gerbillus pyramidum) Similarities and differences and the degree of kinship between these species was through genetic studies through the study of numbers and structures of chromosomes for each species, biochemical studies through protein and molecular through the level of DNA located in mitochondria (mitochondrial DNA). Chromosomal studies: G-banding pattern analysis showed clear successive dark and white bands, which characterized each chromosome pair in both species and facilitated accurate arrangement of chromosomes in pairs. G-banding
