"Ok class," said Mr. DNA "Today we're going to 

learn about what I do for a living.   I am DNA. I 

contain all genetic information for an 

organism." 

"My backbone is made up of three molecules, a 

phosphate, a deoxyribose sugar, and a nitrogen 

containing base.   These groups are called nucleotides.  

Each nucleotide is connected with hydrogen bonds.

When I want to have kids, I undergo 

Replication. My body its slip apart by 

my friend Dr. Helicase. I am now split 

into two halves. 

Wow!!!

Let's see if you have been paying attention. 

Summarize the first step I have described so 

far into a couple of sentences.

If you wrote that my backbone was made of 

nucleotides that contain a phosphate, 

deoxyribose sugar, and a nitrogen containing 

base, then you have been a good student!

After I split, my neighbor, Mr. DNA Polymerase, 

helps each half find more nucleotides to join the 

halves and create 2 new DNA strands. 

Teach us more, 

teach us more!

Ok kids, time to start a new adventure. My 

cousin RNA Polymerase comes by and 

copies half of my information. The copy of 

the information is called RNA. mRNA is 

then my mailman who sends the 

information to the ribosomes. This process 

is called Transcription.

Pop Quiz! Who copies 

half of my information?

My cousin RNA Polymerase 

of course!

Once the information reaches the ribosome, 

Senor rRNA helps the ribosome create amino 

acids. Then, Ms. tRNA reads the mRNA and 

translates it into proteins in a polypeptide 

chain. This process is called translation.

Who helps the ribosome 

create amino acids?

Mi amigo, Senor rRNA!

A codon is a group of three nucleotides in DNA, 

mRNA, and rRNA. Anti-codons, are a group of 

three nucleotides in tRNA. They are made up 

of the complementary base pairs. 

YAY!

Check up time: What are a group 

of three nucleotides in tRNA?

ANTI CODONS!!!!!!!!!!!!!!!!!!

Papa Endoplasmic Reticulum always has ribosomes 

attached to its hip. He sends the ribosomes to school, 

at the Golgi Apparatus High. There, they learn, and are 

packaged and sent off elsewhere to a job.

Who sends his ribosome children 

to school, where they learn, are 

packaged, and are sent off?
