The document explains the process of protein synthesis, detailing the roles of DNA, mRNA, and tRNA. It describes how mRNA carries genetic information from DNA to ribosomes, where ribosomes synthesize proteins by assembling amino acids in the correct order based on the mRNA sequence. The document highlights the importance of tRNA as an adapter molecule during translation, linking amino acids to the mRNA template.

Protein syntesis

2. DNA
 DNA containsthe necessary information for the work and build of a cell.
 DNA is made up of Nucleotides

3. RNA
 In protein syntesis tRNA and mRNA are involved.
 tRNA means Transfer RNA.
 mRNA means messenger RNA.

4. mRNA
 In protein syntesis mRNA is used forcarryng the information from the
DNA that is going to be used in translation (we will see this later).
 Is also made up of Nucleotides.

5. tRNA
 tRNA is involved in translation of the nucleic acid message from the
mRNA into the amino acid of the protein.
 In translation it takes the role of an adapter molecule.
 tRNA have a inverted L structure.
 It have and anticodom loop which pairs with a mRNA. This says the
specific type of Protein that must be created.

7. Ribosome
 A ribosome is a component of cells that synthesizes protein chains. It
assembles the twenty specific amino acid molecules to form the
particular protein molecule determined by the nucleotide sequence of
an RNA molecule.
 It runs a very important role in Protein Syntesis. A big part of the
process occurs here, that is called Translation, in the Ribosome.
 The synthesis of proteins is catalyzed by the ribosome.

8. How do this work?
 DNA Pre mRNA mRNA Ribosome
Protein tRNA
Transcription RNA Procesing
Translation

9. THE PROCESS
 This process consist to create proteins.
 A particualr section of DNA codes for a particular protein.
 The mRNA has the job of passing the information from the DNA and
carry out from the nucleus to the cell cytoplasm in the Ribosomes.
 RNA is smaller than DNA and can easily go in and out the pores in the
nucleus membrane.
A section of DNA =is equal to the needed= protein.

10.  The next point is create the Protein and this occurs in the Ribosome.
 The mRNA kind goes through the ribosome like a zip in a zipper.
 As it goes through the ribosome it codes for particular amino acids in a
particular order... Here tRNA takes part.
 tRNA are floating around ribosome and have amino acids attached to
them. They come in and tRNA attach to mRNA and the ribosome joins
the amino acids together as they go through.
 the tRNA then go off again and get another amino acid.
 They transfer the amino acids from being single units to the ribosome
so they can be made into a long chain.
 This will be made into proteins later.

11. This picture shows from DNA transcription to tRNA, that
is creating a protein
Protein

12. Resume
 The information in DNA is first transcribed into messenger RNA.
The process of converting the genetic message found in mRNA to an
amino acid sequence is called translation or protein syntesis.
In translation tRNA attached to mRNA and
join the amino acid in long chains.
