How to add sequence data into a sequence database

I wish to add new data into a sequence database (49x1 cell). I have the database created as presented below from dataset D2 (72x6). I wish to add new dataset D3(72x6) into the seqhence database to have (121x1 cells). Please How do I proceed. I am a novice at the moment.

clear,clc;
