Self-reactive B cells can undergo receptor editing.

In this process, the antigen-specific V region is “edited” or switched for a different V-region gene segment via V(D)J recombination,

The snoRNAs are 60 to 300 nucleotides long. Many are encoded within the introns of other genes and cotranscribed with those genes. Each snoRNA includes a 10 to 21 nucleotide sequence that is perfectly complementary to some site on an rRNA.

G-tail is probably generated because there is a specific limited degradation of the C-A–rich strand.
