Score Table

Table containing the score explanation. Score identify the level of experimental reliability and evidence so as exaplained in the 2023 release manuscript. Class 1 should be considered as highlyrelevant. Class 2 evidences are considered as Solid, namely large errors are unlikely and minor errors should not undermine the meaning of data. Class 3 is considered as speculative and errors are expected. Class 4 is considered as questionable. Class 5 evidence means that verification and data are still to be collected. Class 6 data cannot be estimated.
Method Classification Score
Multiple direct experimental evidence 1
Direct experimental evidence 2
Inferred based on indirect experimental evidence 3
Predicted computationally 4
Evidence not yet annotated (Unknown) 5
Irrelevant 6

Comments:

Heteroplasmy in mitochondria refers to the coexistence of distinct forms of mitochondrial DNA within a single cell or individual. In the specific context of mitochondrial tRNA sequencing, both adenine (A) and uracil (U) were detected at position 48 in the tRNA sequence. This observation is attributed to mitochondrial heteroplasmy, indicating that the cell's mitochondrial population contains a mix of tRNA molecules with either A or U at this position. This could have implications for mitochondrial function and warrants further investigation.



Modification Positions

Table containing the original modifications present in the MODOMICS sequences. Edit locations not originally present in the RNA sequences are marked by their source. Their scores are in third row.

Modification Annotation

Table containing the data present in the literature relating to the modification positions present in the RNA sequences. Some of the modified residuals may differ from the modifications originally present in MODOMICS. It follows the same format as the previous table. The table reports the scores that have been associated to the modified nucleotides so to have an estimation of the reliability of their presence.
