Abstract

The conservation of genetic resources using knowledge of the genetic structure and the study of mitochondrial genome between and within species is an appropriate indicator of genetic diversityfor population genetic study and Non-coding genes of 16sRNA, 12sRNA, and tRNAs are regulatory elements involved in mitochondrial replication and transcription. For these reasons, in the current research, sequences of 2 rRNAs and 22 tRNAs were compared and analyzed with bioinformatics analysis of the mitochondrial genome in one humped camel and two-humped camel. The results showed that 6 nucleotides of 16sRNA sequence, 45 nucleotides of 12sRNA and 44 nucleotides of tRNAs were varied in comparing the sequences of non-coding RNA genes of one-humped and two-humped camels, which only two genes of rRNA and four genes from tRNAs were significant for Neutrality tests. Investigating the structural implications of these variable nucleotides using modeling confirmed that only the variable nucleotides in the D ring of the tRNA-Trp gene caused the spatial deformation of the cloverleaf form of tryptophan tRNA and Gibbs' free energy. Based on the results of this research, non-coding RNA genes of mitochondrial genome of camel species are conserved.
