16” fluorescent light LED conversion. Wiring question.

So I bought my roll of LEDs, cut to fit, wired + to +, - to - but only the first strip lights, which was the first one off the reel.

So when you cut the strip, does the wiring need to re connect the cut strips in the order they came off the reel?

In other words, a 16” strip has an anode and a cathode?
