Hank gives us a tour of the most important table ever, including the life story of the obsessive man who championed it, Dmitri Mendeleev. The periodic table of elements is a concise, information-dense catalog of all of the different sorts of atoms in the universe, and it has a wealth of information to tell us if we can learn to read it.

DNA Song. Here is a song I made for a student to help the study. I hope you enjoy!
Here we go, genetic code, determines how you live
Oh size, shape, color and all makes you who you is
You should know the chromosomes has thousands of genes
A T and G C makes types of proteins
During synthesis, the cell uses info
From a gene on a chromosome
Out in the cytoplasm and on the ribosomes
Info needs to get out the nucleus
It's the DNA, in ya
It's the genetic code, in ya
Paring Nitrogen bases, in ya
The double helix ladder, in ya
Oohh
Adenine goes with Thymine
And Guanine pairs with Cytosine
Matched pairs of DNA, bases
How cells produce proteins
Ooh, no, no, no
Send, send, send the code out to the cytoplasm
This genetic messenger is ribonucleic acid
RNA, DNA, differ in many ways, yeah
RNA molecules look like one side or strand
Ribonucleic acid has a different sugar
Has uracil instead of thymine
Messenger RNA sends info out to the cytoplasm
Transfer adds amino acids to proteins
It's the DNA, in ya
It's the genetic code, in ya
Paring Nitrogen bases, in ya
The double helix ladder, in ya
Oohh
Adenine goes with Thymine
And Guanine pairs with Cytosine
Matched pairs of DNA, bases
How cells produce proteins
Messenger RNA production
Ooh, attaches to a ribosome
Transfer attaches to messenger
Ribosome releases, the completed protein chain
But don't you know it's the DNA, in ya
It's the genetic code, in ya
Paring Nitrogen bases, in ya
The double helix ladder, in ya
Oooh
Adenine goes with Thymine
And Guanine pairs with Cytosine
Matched pairs of DNA, bases
How cells produce proteins
Yeah, how cells make proteins
It's in the DNA
Ooh how cells make proteins
No, no, no, no
It's time to introduce the Plant Cell clique!

NUCLEUS:
Welcome to the plant cell
time to introduce
I’m the nucleus
I run this clique
you know I got the juice
an envelope has got my back
I’m the #1 OG
which is short for “Organelle”
So let’s meet the family!
CELL WALL:
First up the cell wall
Here’s to tell y’all
I hold the cell up so it don’t fall
I stand tall
keep us shaped up
square so we don’t look whack
‘cuz you know plant cells
are stacked on stacks of stacks...
CELL MEMBRANE
And if you wanna get in
I maintain
you gotta get past me
Who? The cell membrane!
Regulating what comes out and goes in
like a door man
I’m letting all my bros in
We are the parts of the plant cell
this flow gets growing and we represent well
getting energy from rays of light
making mitosis by the end of the night
we are the parts of the pant cell, yeah!
MITOCHONDRIA:
Can I go next?
NUCLEUS:
Hold up mitochondria — you’re the powerhouse of the cell, man, they aint ready for you!
MITOCHONDRIA:
Awww, okay…
NUCLEUS:
E.R. — hit us with that fire!
ENDOPLASMIC RETICULUM:
Last name: Reticulum
First: Endoplasmic
Haven’t heard of me? Well
That’s tragic
Moving proteins from one spot to another
They’re made by ribosomes
NUCLEUS:
Who dat?
ENDOPLASMIC RETICULUM:
My baby brother!
CHLOROPLAST:
Woah woah!
slow your roll
Hand on the mic, I’m in control
No need to move so fast
‘cuz now
you’re dealing with the chloroplast!
Got a nice fat sack of chlorophyll
so looks like it’s about time time to get chill
sun rays beat down like a sizzle
so Photosynthesizzle what I do fo’ rizzle
We are the parts of the plant cell
this flow gets growing and we represent well
getting energy from rays of light
making mitosis by the end of the night
we are the parts of the pant cell, yeah!
MITOCHONDRIA:
Ok NOW can I go?
NUCLEUS:
Ok Mitochondria, go for it!
MITOCHONDRIA:
Alright, just need to take a quick breath first…
MITOCHONDRIA:
I gotta move quick
I gotta move fast
In the plant cell clique
with Chloroplast
We work together, see?
Photosynthesis to energy
I make it look easy
So run & tell that & don’t step to me
I’m the finest MC
in the microscopic nation
take a deep breath
call that cell respiration
powerhouse
I power up
My engine drives that flower up
Not bragging, just to tell ya
Zinnia to Azelia, Photosynthesis won't fail ya!
We are the parts of the plant cell
this flow gets growing and we represent well
getting energy from rays of light
making mitosis by the end of the night
we are the parts of the pant cell, yeah!

SUMMARY: This karaoke-style music video provides a musical explanation of the structure of the cell membrane. This includes the structure of phospholipids, the key structural component of biological membranes, and how phospholipids interact with water to organize themselves into a phospholipid bilayer. The roles of membranes proteins, carbohydrates, and cholesterol is also discussed.

Lyrics:
If you're in a cell's cytoplasm, heading outside,
Your last stop's a barrier, 8 nanometers wide,
The cell membrane: our subject for today
It's as basic to life as DNA
It's Selectively permeable, like a border patrol
of a country it maintains control.
Selecting what leaves or what gains entry
It's a guard, bouncer, watchman, patrolman or sentry.
But not just a guard, it sends signals in nerves
White blood cells use their membranes to eat germs like hors d'oeuvres,
Membranes have receptors, enzymes and junctions,
So what kinds of structure can have all these functions?
CHORUS
C-E double L, "Mem" B-R-A-N-E
Controlling transport selective permeability
Phospholipids, Carbohydrates, Proteins and Cholesterol
The Fluid Mosaic Bilayer in us all
So let's take a look at what makes up the membrane,
Phospholipids rule this domain,
In fact membrane structure emerges directly
from phospholipids' chemical properties.
There's a head and a tail on every phospholipid,
The tail's two long chain fatty acids
Bound to a glycerol, it's made to order
The tail's non-polar --hydrophobic-- fears water
The head's got a phosphate, it's charged negatively,
makes the head hydrophilic--plays in water happily
So tail avoids water while the head's attracted to it,
When phospholipids form the membrane that's how they do it.
Cause when phospholipids into water get submerged,
A phospholipid bilayer structure will emerge
The tails hang together in a water free zone,
Hear their hydrophobic moan, "water leave me alone!"
While the heads are sticking out touching all those H2Os
Tails in, heads out, it's how every membrane goes
Tails in, heads out, in a cellular sphere,
It's the bilayered basis of membranes everywhere.
CHORUS
But a cell membrane's not just a phospholipid scene
There's cholesterol, carbohydrates, lots of proteins.
In fact, membrane proteins have a presence so great,
that they often exceed the phospholipids by weight.
And all of these components are in constant motion,
Moving, mixing like a boiling potion,
Flowing like dancers in a party in Pasaic
That's why the membrane's thought of as a fluid mosaic.
Let's start with proteins since they're key in this mix.
Transmembrane proteins span the entire width.
Typically they're ports--think of channels or conveyors,
For things that don't go through the lipid bilayer.
Any protein embedded in the hydrophobic middle
Built right into the inside is considered integral
While peripheral proteins either hang on the exterior,
Or inside on the cytoplasmic interior.
Cholesterol keeps membranes flowing with ease,
In cold it keeps the lipids moving so they don't freeze,
In heat it slows the lipids down limiting their traveling,
Cholesterol: it keeps membranes from unraveling
Membrane carbohydrates work as markers or signs
So your immune system knows which flag your cells are flyin'
The blood types AB, O, and B and A
Are about the carbohydrates on red blood cell membranes.
CHORUS
The Cell Theory Song
Mr. Tamez
Lyrics:
CHORUS
All living things are composed of cells
Cells are the basic units of structure and function in living things
New cells are produced from existing cells
VERSE 1
Back then was a guy named Hooke, cut some cork and he had a look
Underneath his microscope tiny rooms that he saw in groups
Empty rooms that looked like shells He's the one that called them cells
Listen up cause we're not done Cell theory had just begun
Add one scientist to know the inventor of the microscope
Anton von Leeuwenhoek saw cells move and he was like "That's dope"
PRE CHORUS
Cell theory, cell theory, cell theory, cell theory, cell theory, go!
VERSE 2
If you thought this was complete take a breath and have a seat
Two scientists to have their say Schleiden and Schwann to save the day
Schleiden said all plants have cells they are alive and we can tell
The next year Mr. Schwann could see all animals have cells that live and breathe
Oh they live and breathe Live and breathe
BRIDGE
In 1855, Rudolph Virchow proposed that all cells
Come from other cells
This was the final discovery
That ended cell theory cell theory
