Lyrics
Deoxyribonucleic
Acid
Contains your genetic code
DNA, a molecule that makes up all your chromosomes
Double helix structure, a two-stranded spiral
A set of instructions for your cells so that they know
What to do like send nerve signals and make new bones
Making proteins from acids amino
A complete set of genetic instructions is a genome
Nucleotides make chains and have three things that they're composed
That's phosphate, nitrogen base and deoxyribose
Each nucleotide base is made up of these four:
Adenine, guanine, thymine, cytosine and that's all
A always pairs with T and that's the base pair rule
C always pairs with G and the way they go
Deoxyribonucleic, DNA is deoxyribonucleic acid, yeah
Deoxyribonucleic, DNA is deoxyribonucleic acid, yeah
These complementary bases each on opposite strands
You can remember the pairs with the mnemonic GCAT
A tightly controlled complex process to make a protein from a gene
It goes Transcription and Translation, two major steps in the journey
Transcription takes information, transfers to mRNA
Messenger moves to the nucleus and onto the next stage
This is called translation, it happens in the cytoplasm
Ribosomes read the codons,
tRNA makes proteins one acid amino at a time
Deoxyribonucleic, DNA is deoxyribonucleic acid, yeah
Deoxyribonucleic, DNA is deoxyribonucleic acid, yeah
