First block, quiz on Monday on THE paragraph!!!

here's the paragraph!
First thing that happens when your body needs a protein is chemical message is sent. mRNA responds by traveling into the nucleus. An enzyme then unzips the DNA molecule so that the mRNA can read the gene that codes for the needed protein. When mRNA creates the message from DNA it places complimentary nitrogen bases in the corresponding order. This process is called transcription. mRNA then leaves the nucleus and travels through the cytoplasm. It locates a ribosome that will read the "message." The ribosome reads the mRNA message in sets of 3 letters, these sets are called codons!
Each codon codes for an amino acid.
The Ribosome then sends a signal to the tRNAs telling them they are needed! The tRNAs then returns to the ribosome with the appropriate amino acids. The anti-codon on the bottom of the tRNA makes sure that the amino acid is returned to the proper location on the mRNA strand. The amino acids are connected via peptide bonds!!
When the chain of amino acids is complete it is released from the ribosome, it folds and is now officially a protein!!! TRANSLATION is done!
THE SONG:
There’s adenine and thymine
Cytosine and guanine
A phosphate and a sugar
And that makes DNA
DNA(clap, clap) DNA( clap, clap) DNA,DNA, DNA (clap, clap)
When thymine goes a missin’
Uracil is there to listen
It sends a little message
Because it’s RNA
RNA (clap, clap) RNA (clap, clap) RNA, RNA, RNA (clap, clap)
Transcription’s then completed
the code gets translated
acids are created
Then proteins are made!
Hip hip hooray! (clap, clap) Hip hip hooray! (clap, clap)
proteins are made, proteins are made, proteins are made!!!!! (clap, clap)
THE STRUCTURE OF AN ACTUAL DNA STRAND IS SIMPLE AND BASIC, IT’S THE PATTERN OF THE CODE AND THE LENGTH OF THE CHAIN THAT MAKE DNA VALUABLE AND YOU UNIQUE!!!!
REMEMBER YOUR ORGANIC COMPOUNDS? THE SMALLEST FUNCTIONAL UNIT OF A NUCLEIC ACID IS A PHOSPHATE, A SUGAR AND A NITROGEN BASE EITHER ADENINE, THYMINE, CYTOSINE, GUANINE (URACIL REPLACES THYMINE IF IT IS A STRAND OF RNA INSTEAD OF DNA).
