Little Mix - Dna chords

I quickly worked these out. Little mix's new song, it sounds amazing, hope they do 
an acoustic! easy chords, everything standard, no capo no special tuning. Infact, 
most of the chords are the same as 'wings'.. enjoy!

Em                  G                          D        A
Does he tell you he loves you when you least expect it?
Em                  G                          D        A
Does he flutter your heart when he kisses your neck
Em                 G
No scientist, or biology
D                       A
It’s obvious, when he’s holding me
Em                G           D         A
It’s only natural that I’m so affected

Em,G,D,A
And my heart won’t beat again
If I can’t feel him in my veins
No need to question, I already know

            Em
It’s in his DNA
      D
D-d-d-dna
            G
It’s in his DNA
    A                Em  
And he just takes my breath away
    D
B-b-breath away
          G              A                   Em
I feel it every day, and that’s what makes a man
    D       G          A
Not hard to understand

Em, D, G, A
Perfect in every way
I see it in his face
Nothing more to say
It’s in his d-d-d-dna

(repeat verse 1 chords)
[ Tab from: http://www.guitaretab.com/l/little-mix/333354.html ]
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 oh

And my heart won’t beat again
If I can’t feel him in my veins
No need to question, I already know

(repeat chorus)

It’s in his DNA
D-d-d-dna
It’s in his DNA
And he just takes my breath away
B-b-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 d-d-d-dna

Em (or E?)
It’s all about his kiss
G
Contaminates my lips
D
Our energy connects
A
It’s simple genetics
Em (or E?)
I’m the x to his y
G
It’s the colour of his eyes
D
He can do no wrong
A
No he don’t need to try
Em (or E?)
Made from the best
G
He passes all the tests
D
Got my heart beating fast
A
It’s cardiac arrest
Em (or E?)
He’s from a different strain
G
That science can’t explain
D
I guess that’s how he’s made
A
In his d-d-d-dna


(repeat chorus)

It’s in his DNA
D-d-d-dna
It’s in his DNA
And he just takes my breath away
B-b-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 d-d-d-dna
