johnnynyc00 - dna replication rap lyrics

[intro]
dna replication
by – johnnynyc00

deoxyribonucleic acid
you need that replicated so so rapid
cuz what that is is your dna
if you don’t have that coming your way
you better pray
cuz you ain’t here to stay
you goin away
dna stores your genetic information
you need that for dna replication
but i’ll talk about that later when i get into that station
nucleic acid is it a polymer, nucleotide?
come on man decide!
actually it’s a polynucleotide
you need em by your side
if you didn’t have em you would have already died
so right now let’s just talk about the nucleotide
it’s made up of 3 things so keep em close
a phosphate, nitrogen base, and deoxyribose
it’s a sugar molecule just like glucose
but it’s got a five carbon dose
so don’t call it fructose
or i’ll say adios
but what makes you, you? it’s the nitrogen bases
thats’ what makes people have such distinct faces
there’s adenine, thymine, cytosine, guanine
all of these combined it’s what makes up your gene
a can only bind with t and c can only bind with g
that’s just the way it has to be
because they’re base pairs as you can see
hydrogen bonded making them unfree
a and t have 2 while c and g have 3
dna is a double helix, not a single strand
so it needs support to help it stand
sugars and phosphates lend a helping hand
so no dna strand is left alone
they form the twin backbone
these backbones each in their own section
face an opposite direction
one start at the sugars 5th carbon while the other the third
because that is the way it is preferred
5 prime to 3 prime or 3 prime to 5 prime
all depends on the side of the enzyme. it’s a simple paradigm
let’s get back to dna replication
so listen up with complete concentration
it happens in the s phase of interface
but it needs an enzyme called helicase
unwinding the helix like untying a shoelace
breaking the hydrogen bonds between the bases like a pitchfork
leaving behind what we call the replication fork
where the splitting starts and dna starts to disband which has a top and bottom strand
called lagging and leading which is needed for the replication to continue proceeding
there’s an enzyme called dna polymerase adds matching nucleotides down the strand at its own pace
but it can’t start without a primer provided by rna primase which it use as a base
so it can start to build all the empty base pairs which will now start to be filled
this is only for the leading where it is most sk!lled because from 5 prime to 3 prime it can only build
when it comes to the lagging strand we have an incident
since it’s 3 prime to 5 prime the polymerase cannot augment it must be done in different segments
so multiple primers must be present for polymerase to build off backwards on occasions very frequent
we call these parts the okazaki fragments then a new polymerase replaces the rna primers doing its job 100 percent finally an enzyme called dna ligase comes to inspect
making sure all fragments are sealed and connects making sure nothing goes unchecked repairing everything making it perfect
the dna is now replicated and can go into effect
yeah
the dna is now replicated and can go into effect
done
