[Verse 1: Perrie]
Does he tell you he loves you when you least expect it?
Does he flutter your heart when he kisses your neck?
No scientist or biology, it's obvious, when he's holding me
It's only natural that I'm so affected

[Pre-Chorus: Jade]
Oh, and my heart won't beat again
If I can't feel him in my veins
No need to question
I already know

[Chorus: All]
It's in his DNA, DNA, it's in his DNA
And he just takes my breath away, breath away, I feel it every day
And that's what makes a man, not hard to understand
Perfect in every way, I see it in his face, nothing more to say, it's in his DNA

[Verse 2: Jesy & (All)]
It's the blue in his eyes that helps me see the future
Fingerprints that leave me covered for days, yeah, hey, yeah
(Now I don't have any first degree, but I know what he does to me)
No need to work it out, it's so familiar (No) Oh

[Pre-Chorus: Jade & (All)]
And my heart won't beat again
If I can't feel him in my veins
No need to question
I already know (I already know)

[Chorus: All]
It's in his DNA, DNA, it's in his DNA
And he just takes my breath away, breath away, I feel it every day
And that's what makes a man, not hard to understand
Perfect in every way, I see it in his face, nothing more to say, it's in his DNA

[Post-Chorus: All]
It's in his DNA, in his, in his DNA, it's in his DNA, DNA
It's in his DNA, in his, in his DNA, it's in his DNA, DNA

[Bridge: Leigh-Anne & (All)]
It's all about his kiss, contaminates my lips
Our energy connects, it's simple genetics
I'm the X to his Y, it's the colour of his eyes
He can do no wrong, no, he don't need to try
(Made from the best, he passes all the tests
Got my heart beating fast, it's cardiac arrest
He's from a different strain that science can't explain
I guess, that's how he's made, in his DNA)

[Chorus: All & Perrie & (Jesy) & {Jade}]
Oh, oh, oh It's in his DNA, DNA, it's in his DNA
And he just takes my breath away, breath away, I feel it every day
And that's what makes a man (What makes a man)
Not hard to understand {To understand}
Perfect in every way {In every way} I see it in his face {In his face} Nothing more to say {Nothing more to say} It's in his DNA
