No science or biology It's obvious when she's holding me It's only natural that I feel so affected Oh And my heart won't beat again If I can't feel her in my veins No need to question, I already know It's in her DNA, D-D-D-DNA It's in her DNA She just takes my breath away B-B-Breath I feel it every day And that's what makes me want her It's not hard to understand Perfect in every way I see it in her face Nothing more to say It's in her D-D-D-DNA It's the blue of her eyes that helps me see the future Fingerprints that leave me covered for days, yeah hey yeah Well, I don't have a degree But I know what she does to me No need to try, it's so familiar, oh And my heart won't beat again If I can't feel her in my veins No need to question, I already know It's in Her DNA, D-D-D-DNA It's in her DNA She just takes my breath away B-B-Breath I feel it every day And that's what makes me want her It's not hard to understand Perfect in every way I see it in her face Nothing more to say It's in her D-D-D-DNA It's just her kiss, it taints my lips Our energy connects, it's simply genetic I'm the candy to her mouth, it's the color of her eyes She can't make mistakes, no, she doesn't even have to try Made of the best, she passes every test Makes my heart beat fast, it's a heart attack She's from a different lineage that science can't explain I guess that's how she was made in her D-D-D-DNA It's in her DNA, D-D-D-DNA It's in her DNA It just takes my breath away B-Breath I feel it every day And that's what makes me want her (makes you want her) It's not hard to understand (understand) Perfect in every way (every way) I see it on her face (on her face) Nothing more to say (nothing more to say) It's in her D-D-D-DNA
