For the Life Sciences Crowd

Biology covers cells, organisms, reproduction and evolution, which means roughly half the vocabulary is already suggestive before anyone touches it. This is our full list of biology pick up lines, ranked by reader votes. They suit students, lab partners, medics and anyone who can name the parts of a cell without looking. Expect DNA jokes, mitochondria references that have long since become a meme, and several about natural selection that are cleverer than they first appear. The clean ones work in a lecture hall. The rest are best saved for the bar afterwards.

The Best Biology Pick Up Lines

Describe the type of pick up lines you want:

You're so hot, you denature my proteins.

If I was an enzyme, I'd be helicase so I could unzip your genes.

You must be the one for me, because my selectively permeable membrane let you through.

Lets unzip our genes and see if we can share codes together.

Baby, you give me sudden protracted cardiac arrhythmia every time I see you.

Baby, every time i see you, my cardiovascular system gets all worked up.

Hey baby, will a little more alcohol catalyze this reaction?

My eyes stick to you like histones on DNA.

Falling in love with you takes less time than my DNA takes to replicate.

Want to be my substrate/enzyme?

You give me more jolt than a mitochondria!

The inhibition markers on my DNA must be blocked, because I can't seem to stop myself from hitting on you.

You are the glue that links my Okazaki strands together.

I've been single-stranded far too long! Lonely ATGCATG would like to pair up with congenital TACGTAC.

My hypothalamus must be secreting serotonin because baby, you make me happy!

DNA spelled backwards is AND, as in... me AND you.

Do you like aerobic respiration as much as I do?

You make my anoxic sediments want to increase their redox potential.

You're so cute you make my zygomaticus muscles contract.

You’ve got me feeling more excited than a cell entering interphase.

Are you an endoplasmic reticulum? Because you make my heart’s proteins run smoothly.

I’d cross every ecological niche just to find a habitat beside you.

Are you a catalyst? Because you make my feelings happen much faster.

You’re like a beneficial mutation: rare, unexpected, and wonderful for my survival.

Are you a biologist? Because you’ve got me making observations about your beautiful adaptation.

My heart is undergoing mitosis—the moment I saw you, it doubled in size.

Are you a petri dish? Because our connection deserves a culture of its own.

You must be an allele, because you’re the dominant feature in every room.

Are you a protein? Because you’re folding perfectly into my life.

I think we’re in the same food chain, because I’m totally consumed by you.

Are you a vacuole? Because you’ve made a huge space in my heart.

Are you a fossil? Because I’ve been searching ages for someone like you.

You’re the only specimen in this room I’d happily study for hours.

Are you a codon? Because you’re the perfect three-letter word: date with me?

My love for you is like binary fission—it keeps multiplying.

You must be a stem cell, because you have the potential to become everything I’ve dreamed of.

Are you a food web? Because I’m tangled up in you and loving every connection.

You’re so charming, even my circadian rhythm wants to stay up talking to you.

Are you a lysosome? Because you break down all my defenses.

Our attraction has more pull than a carnivore spotting an unattended picnic.

Are you an organelle? Because you’re a small part of my world with a huge impact.

I’d never take you for granted—you’re the rarest species in my personal habitat.

Are you an RNA strand? Because you’ve got the message my heart has been waiting to translate.

You must be a hormone, because you’ve completely changed my behavior.

Are you a taxonomist? Because you’ve classified yourself as my favorite person.

I’d say you’re out of my phylum, but I’d still love to evolve toward a date.

Are you a feedback loop? Because every time you smile, my feelings grow stronger.

You must be chlorophyll, because you’ve turned my gloomy day green with envy.

If I were a virus, I would infect you with my love.

If my right leg is the cell wall and my left the membrane, do you want to be the cytoplasm?

I wish I was adenine so I could get paired with U.

I must be a CRISPR enzyme, because I feel like I was made to edit your genes into my future.

Are you a PCR machine? Because you just amplified my feelings.

If we were like chromosomes, you’d be my homologous pair.

I’m confused because you look like a knockout and a wild-type.

Are you mitochondria? Because you’re giving me the energy to ask for your number.

Are you DNA polymerase? Because you’ve got me replicating this crush all over again.

You must be a ribosome, because you’re making my heart produce proteins.

Are we in the same ecosystem? Because I feel a natural attraction between us.

Are you natural selection? Because you’re exactly the type I’ve been looking for.

You’re like homeostasis—you make everything in my life feel balanced.

Are you a neuron? Because you just sent sparks through my entire nervous system.

Are you a plasmid? Because I’d love to share some genetic information with you.

Are you an enzyme? Because you’ve lowered my activation energy for falling in love.

You’re so attractive, even my recessive genes want to express themselves around you.

Are you a cell membrane? Because you’re selectively letting your way into my heart.

You must be osmosis, because I feel drawn toward you without knowing why.

Are you a microscope? Because you make the tiniest moments with you feel enormous.

You and I have serious chemistry—should we test the hypothesis over coffee?

Are you a chromosome? Because you’ve got exactly the traits I’d want to inherit.

I must be a macrophage, because I’d gladly engulf all your attention.

Are you an antibody? Because you’re the perfect match for my antigen.

You’re like ATP: you power every thought I have about asking you out.

Are you a flower? Because I’m positively buzzing for a chance to pollinate your schedule with a date.

You must be a gene mutation, because you’ve changed everything about my usual type.

Our chemistry is so strong, even the lab goggles can’t contain it.
