Lemme tell you ‘bout this cycle, it’s the way that cells survive, If they don’t go through it right, then they ain’t gon’ stay alive. (Verse 1) First we in G1, cells be growing, get strong, Stacking up them proteins, making sure it’s movin on. If it’s good, then we slide, now we heading to that S, DNA gon’ replicate, make sure it’s prepped the best. Two copies of the genes, yeah, they doubling up the code, If mistakes be popping up, then that cell just might explode! (Pre-Chorus) G2 phase next, gotta check if all is straight, Fix the errors in the system ‘fore it try to duplicate. If the DNA look solid, if the cell be looking right, Then we heading to mitosis, where that cell gon’ split tonight! (Chorus) It’s the cycle, yeah, that cell keep going round, Grow, divide, split, now it’s two up in the town. Interphase, mitosis, cytokinesis, then repeat, Cells be multiplying quick, yeah, they never miss a beat! (Verse 2) Now we in M phase, mitosis just begun, Prophase first, chromosomes getting spun. Nuclear membrane break, centrioles on the move, Metaphase coming next, lining up right in the groove. Anaphase hit, chromatids pull apart, Spindle fibers tug ‘em back, gotta play their part. Telophase close, two nuclei in the set, Now we splitting all the way, cytokinesis next. (Pre-Chorus) Now we got two, looking fresh, looking mean, Each one got the DNA, copy game clean. But if something go wrong, cell ain’t making it through, Apoptosis come around, now that cell is through! (Chorus) It’s the cycle, yeah, that cell keep going round, Grow, divide, split, now it’s two up in the town. Interphase, mitosis, cytokinesis, then repeat, Cells be multiplying quick, yeah, they never miss a beat! (Outro) Yeah, that’s the story, how these cells go on and live, Follow all the phases, it’s the cycle that they give. Keep it right, keep it tight, every step, every day, If you really understand it, then you know just what to say!
