YOU + your KID
learn about the function of DNA, RNA, PROTEINS, splicosomes and many more
Find the right GENE on the DNA
TRANSCRIBE the DNA into mRNA
SPLICE the mRNA
TRANSLATE the mRNA into PROTEIN



 
 
LEVELS
 
1
FIND
the GENE on the DNA.
 
01
 
The beginning of the
GENE is marked by the
INITIATION SITE,

a special sequence of
NUCLEIC ACIDS.
 
Double Helix
GENES are segments of the DNA double helix.

DNA is a sequence of
NUCLEIC ACIDS.
GENES encodes the PROTEINS we want to create.
Protein
The GEOMETRY of the PROTEIN provides its FUNCTION.
→ start to create a PROTEIN


"It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material."
James Watson, Francis Crick
 
2
CREATE
mRNA – transcribe the GENE
 
01
 
CONNECT complementray NUCLEIC ACIDS to create a strand of messengerRNA.

A messenger RNA is an
INVERSE COPY of the DNA.
 
mRNA
mRNA is made out of NUCLEIC ACIDS:

Adenine   Guanine   Cytosine   Thymine / Uracil
Cytosine
The COMBINATION provides the ENCODING of the information to create the PROTEIN.
 
→ start the DNA-transcription / GENE→mRNA
 
3
CUT out
non-codig sections from the mRNA
 
01
 
CONNECT the specific
NUCLEIC ACID sequences.
Use the SPLICEOSOME!

EXONS (coding) – are joined together
INTRONS (non-coding) – are
REMOVED
 
Exons (coding) – are joined together
Introns (non-coding) – are removed
 
Whole sections will be cut out and the remaining pieces will we stiched back together.
→ remove the NON-CODING regions
Spliceosome
The spliceosome is actually a whole bunch of proteins, that work together.
 
4
TRANSLATE
the mRNA to build a PROTEIN
 
01
 
I    
TAKE
the mRNA to the
RIBOSOMES.

RIBOSOMES translate the mRNA
into a chain of AMINO ACIDS.
 
01
 
II    
FIND
the right transfer RNA
to fit your mRNA sequence.

1 tRNA contains a set of 3 NUCLEIC ACIDS
1 tRNA 1 AMINO ACID.
 
→ translate the mRNA to build a PROTEIN
Protein
Proteins are the building blocks of life.
Almost every process in our body involves proteins.
They act as enzymes, facilitators and antibodies.
 
Ribosome
 
Proteins are produced by the ribosomes (which is in itself an assembly of many proteins).
Since proteins are made up of 20 different amino acids, three nucleic bases are needed to encode them all. These three bases are called the codon.
tRNA
 
The mRNA is pulled through the ribosome. The ribosome then attaches a special kind of molecule called transfer RNA or tRNA to the mRNA. Each tRNA exposes a three bases long anti-codon.
Each tRNA also carries with it an amino acid, which matches the anti-codon.
 
The ribosome then takes each amino acid, and attaches them one after the other, while the mRNA is pulled through.
 
This is how the mRNA gets translated into a protein. Always three bases at a time.

DNA is located inside the nucleus, while the production of proteins is located outside the nucleus.
