With the help of the list by @reuns, I was able to hunt down some of the mutations in terms of amino acids:
AT.1 has S:ins679GIAL S:N679K (found in a report from Public Health England)
A.2.5 has S:ins214AAG (usually, the insert can have another point mutation to S:ins214ASG, and it can occur reduplicated as S:ins214AAGAAG
B.1.214.2 has S:ins214TDR (found in ...
That's because handling insertions is a bit harder than point mutations and deletions.
With covizu I get this, unfortunately it doesn't tell us the insert and the translation. Hope someone can give a more comprehensive answer
We can calculate the number of base pair copy errors in a Petri dish per hour by multiplying the number of base pairs (B), the copy error rate (P), the number of divisions in an hour (D), and the number of cells in a Petri dish (N). (We assume a stable population in a saturated medium.)
B \times P \times D \times N
I've looked up some articles and ...
