Figure 4.
tRNALys gene lies within cox1 gene. (A) Sample sequence of one of the clones obtained from the analysis of the 3′ extremity of cox1 mRNA. The polyA tail found at the 3′ extremity is indicated by a vertical arrow and the generated stop codon underlined. This confirms the complete expression of cox1. (B) Sample sequence of one of the clones obtained from the cRT-PCR product amplified in the presence of primers specific of A. vulgare mitochondrial tRNALys. The 3′- and 5′- extremities of the tRNA molecule are separated by a vertical arrow. The post-transcriptionally added CCA extremity is underlined. (C) Deduced cloverleaf structure of the A. vulgare mitochondrial tRNALys.
