Welcome to Moof University! My name is Mahfoud, and I recently graduated from UC Riverside. I've made these videos to help students with introductory biochemistry. The videos are loosely structured around what I learned from the elementary biochemistry course I took on campus (BCH 100) at UC Riverside. I hope, however, that any and all individuals who want to learn basic biochemistry find these videos helpful. In addition, if you are a student at UC Riverside taking BCH 100 (or a student at a school near UC Riverside), and you find these videos helpful, but still want more help, please feel free to email me at MoofUniversity@gmail.com if you are interested in my tutoring services.

The ribosome has two subunits: small and large. - Several initiation factors, elongation factors, and release factors. These factors assist with initiation, elongation and termination of the process, respectively. Steps of the translation process: Initiation (eukaryotes) : The small ribosomal subunit binds to the initiator tRNA carrying the initiator amino acid methionine. This complex then attaches to the cap structure at the 5’ end of an mRNA and scans for the start codon AUG. The process is mediated by several initiation factors. At the start codon, the large ribosomal subunit joins the complex and all initiation factors are released. The ribosome has three sites: the A-site is the entry site for new tRNA charged with amino-acid or aminoacyl-tRNA; the P-site is occupied by peptidyl-tRNA - the tRNA that carries the growing polypeptide chain; the E-site is the exit site for the tRNA after it’s done delivering the amino acid. The initiator tRNA is positioned in the P-site. Elongation: A new tRNA carrying an amino acid enters the A-site of the ribosome. On the ribosome, the anticodon of the incoming tRNA is matched against the mRNA codon positioned in the A-site. During this proof-reading, tRNA with incorrect anticodons are rejected and replaced by new tRNA that are again checked. When the right aminoacyl-tRNA enters the A-site, a peptide bond is made between the two now-adjacent amino-acids. As the peptide bond is formed, the tRNA in the P-site releases the amino-acids onto the tRNA in the A-site and becomes empty. At the same time, the ribosome moves one triplet forward on the mRNA. As a result, the empty tRNA is now in the E-site and the peptidyl tRNA is in the P-site. The A-site is now unoccupied and is ready to accept a new tRNA. The cycle is repeated for each codon on the mRNA. Termination: Termination happens when one of the three stop codons is positioned in the A-site. No tRNA can fit in the A-site at that point as there are no tRNA that match the sequence. Instead, these codons are recognized by a protein, a release factor. Binding of the release factor catalyzes the cleavage of the bond between the polypeptide and the tRNA. The polypeptide is released from the ribosome. The ribosome is disassociated into subunits and is ready for a new round of translation. The newly made polypeptide usually requires additional modifications and folding before it can become an active protein.

PNAS 2015-03-25A eukaryote ( /juːˈkæri.oʊt/ ew-KARR-ee-oht or /juːˈkæriət/) is an organism whose cells contain complex structures enclosed within membranes. Eukaryotes may more formally be referred to as the taxon Eukarya or Eukaryota. The defining membrane-bound structure that sets eukaryotic cells apart from prokaryotic cells is the nucleus, or nuclear envelope, within which the genetic material is carried. The presence of a nucleus gives eukaryotes their name, which comes from the Greek ευ (eu, "good") and κάρυον (karyon, "nut" or "kernel"). Most eukaryotic cells also contain other membrane-bound organelles such as mitochondria, chloroplasts and the Golgi apparatus. All species of large complex organisms are eukaryotes, including animals, plants and fungi, although most species of eukaryote are protist microorganisms.
Cell division in eukaryotes is different from that in organisms without a nucleus (Prokaryote). It involves separating the duplicated chromosomes, through movements directed by microtubules. There are two types of division processes. In mitosis, one cell divides to produce two genetically identical cells. In meiosis, which is required in sexual reproduction, one diploid cell (having two instances of each chromosome, one from each parent) undergoes recombination of each pair of parental chromosomes, and then two stages of cell division, resulting in four haploid cells (gametes). Each gamete has just one complement of chromosomes, each a unique mix of the corresponding pair of parental chromosomes.

Aw yeah!
Blood is thick and piss is thin, I'm full of one but
I'm not sure which. Aw yeah!
Cast my line and pulled up teeth, sound violins, I
wanted a ship. Aw yeah!
Called the rain and asked her when? She's found love
never see her again.
(Love won't last, crying again)
Aw yeah!
People trying to remember how did it go? People trying
to forget, and what do you know?
People lost their lust for life, I'm a happening fan.
Let's fix our beds together.
Aw yeah!
Lost my feet but I still run, my hands wear my shoes
and my face is my butt. Aw yeah!
Hounds dogs, blood hounds, outta control, a hot dog's
soft but it's still got bones. Aw yeah!
Well I spit on my grave when I sleep with the twins,
one's for loving, one eats my sins. Aw yeah!
People trying to remember, how did it go? People trying
to forget, and what do you know?
Time and time I seen the light but I wanna explore.
Don't wanna lie in pastures.
I said hey! I got one foot in the grave, yeah one foot
[Hook]
My life be like
Ooh Aah (yeah), Ooh Ooh
My life be like (yeah)
Ooh Aah, Ooh Aah (yeah), Ooh Ooh
Ooh Aah (yeah), Ooh Ooh
My life be like (yeah)
Ooh Aah, Ooh Aah (yeah), Ooh Ooh
My life be like (yeah)
[Chorus (over hook)]
It's times like these that make me say
Lord if you see me please come my way
Leavin' bread crumbs for when I stray
Rely on sacrifice and the price you paid
Feel me like a fingertip (fa-finger tip, fa-finger tip)
Sometimes I fall I slip
My heartfelt desire be more like you
Tryin' not to quench your fire with the things I do
[Verse One: Coffee]
I'm on an island by my lonesome stranded
Low key and stayin' candid
Reflect on all the things I try my hand at
Church for the equations to persuasions I'm used to
Finding comfort in the zones of closet bones I get loose to
A mountainous fontaine
Spinnin' and monsoonin', grinnin' it's hign octane
Explosive how I came
Rollin' down hills cause lifes a hastle
Encircled by my folly like a moat surround a castle
Stay afloat, catch a second wind
Thin
Is the air I breathe
Teary eyed nose runnin' wipe the snot on my sleeve
I'm callin' on the Savior to be all that I need
Please forgive me my behavior had me lost at light speed
[Chorus (over hook)]
It's times like these that make me say
Lord if you see me please come my way
Leavin' bread crumbs for when I stray
Rely on sacrifice and the price you paid
Feel me like a fingertip (fa-finger tip, fa-finger tip)
Sometimes I fall I slip
My heartfelt desire be more like you
Tryin' not to quench your fire with the things I do
[Verse Two: Bonifide]
The fear of never fallin' in love
And the tears after losin' the feelings of what you thought love was
Like the dirt still up under the rug (My life be like)
Bad characteristics covered in Christs blood
The joy of new birth and the pain of growin' up
The bliss between givin' my all and givin' up
The highs and lows
Paths and roads I chose
In the cold I froze
Tryin' to ease my woes
In this world of sin
Clothes to thin to fend
So to God I send
Words of help to win
In grumblings so deep letters could never express
So the sound of Ooh Aah beneath my breath projects
[Chorus (over hook)]
It's times like these that make me say
Lord if you see me please come my way
Leavin' bread crumbs for when I stray
Rely on sacrifice and the price you paid
Feel me like a fingertip (fa-finger tip, fa-finger tip)
Sometimes I fall I slip
My heartfelt desire be more like you
Tryin' not to quench your fire with the things I do
Don't be bad
[Verse Three: TobyMac]
My life be like
Ooh Aah Ooh
Dum dum ditty
Here come that boy from the Capital City
Last up on the Grits new ditty
But eight bars or the truth well do (uh)
I believe theres a private stunnin
And I believe in the Kindgom Comming
I believe if you seek the truth
You don't need to look far cause it's gonna find you
So Why oh Why do I trip and stumble?
And ooh aah as commitment crumbles?
I can't believe that I'm here again...
[Chorus (over hook)]
It's times like these that make me say
Lord if you see me please come my way
Leavin' bread crumbs for when I stray
Rely on sacrifice and the price you paid
Feel me like a fingertip (fa-finger tip, fa-finger tip)
Sometimes I fall I slip
My heartfelt desire be more like you
Tryin' not to quench your fire with the things I do
It's times like these that make me say
Lord if you see me please come my way
Leavin' bread crumbs for when I stray
Rely on sacrifice and the price you paid
Feel me like a fingertip (fa-finger tip, fa-finger tip)
Sometimes I fall I slip
My heartfelt desire be more like you
Tryin' not to quench your fire with the things I do
Fa-finger tip, fa-finger tip
Fa-finger tip, fa-finger tip
My life be like
Fa-finger tip, fa-finger tip
Fa-finger tip, fa-finger tip
Ma-ma-my life be like
Fa-finger tip, fa-finger tip
Fa-finger tip, fa-finger tip
My life be like
Fa-finger tip, fa-finger tip
Fa-finger tip, fa-finger tip
