Computational prediction of over-annotated protein-coding genes in the genome of Agrobacterium tumefaciens strain C58 |
The relative G + C content at the three codon positions. As can be seen, the locating regions of the predicted non-coding genes are obviously different from those of the other genes. Careful observation indicates that the G + C content at the second and third codon positions of the protein-coding genes exhibit high usage bias. On the contrary, the values of relative G + C contents at the three codon positions of the predicted non-coding genes are about 1, respectively, which indicate that they are likely to be random sequences. |
