Answer:
1. transcription of Tau DNA in different directions.
4. different chemical modifications of Tau protein.
Explanation:
Tau gene transcribe in different direction which depends upon the animal age. This happens because at different age and developmental stage, animal produce different RNA binding proteins which leads to formation of alternative splice forms. This reaction is strengthen by the addition of phosphate and sugar molecules which again depending on developmental stage and time.
