T1 cells are mIgMhi, mIgD -/lo, CD21-, CD23-, CD24+, and CD93+. 

T2 cells differ from T1 cells in having higher levels of mIgD and in expressing CD21 and CD23.

Down mutations to decrease promoter efficiency usually decrease conformance to the consensus sequences, whereas up mutations have the opposite effect.

 Mutations in the -35 sequence can affect initial binding of RNA polymerase.

Mutations in the -10 sequence can affect binding or the melting reaction that converts a closed to an open complex.
