Kids learn about proteins and amino acids in the science of biology including how they are made using DNA, transcription, and translation and different types of proteins. Take a ten question quiz about this page. More Biology Subjects. DNA is just one type of nucleic acid. Some other types are RNA, mRNA, and tRNA. All of these "NAs" work together to help cells replicate and build proteins. NA.

The name would eventually be changed to nucleic acid, which is an organic substance found in the nucleus of living cells. From that moment, an exciting race began to try determine what the purpose of this new, mysterious biomolecule was, what its molecular structure looked like, and how it behaved.
Today we know that there are two types of nucleic acids found in every living organism: Together they are responsible for passing an organism's traits to the next generations, including what it will look like and how their body will work.

This seems incredible for a mere chemical that looks like a blob of clear jelly in a test tube. It's difficult to imagine chemicals as having a 'shape,' so let's look a bit more into it to try to understand how the 3D shape of nucleic acids comes about. Like other large organic molecules, nucleic acids are long chains made of individual, repeated units called monomers.
The particular name for the units of nucleic acids are called nucleotides and each contains three things: There are different nucleotides named according to the nitrogenous base they contain: DNA is made up of different sequences of: The RNA is used in the next step, which is called translation. Translation The next step in making a protein is called translation.
This is when the RNA is converted or "translated" into a sequence of amino acids that makes up the protein. The translation process of making the new protein from the RNA instructions takes place in a complex machine in the cell called the ribosome.
The Nucleic Acids
The following steps take place in the ribosome. The RNA moves to the ribosome. It is abbreviated as mRNA where the "m" is for messenger.
The mRNA attaches itself to the ribosome. The ribosome figures out where to start on the mRNA by finding a special three letter "begin" sequence called a codon. The ribosome then moves down the strand of mRNA. Every three letters represents another amino acid molecule.

The ribosome builds a string of amino acids based on the codes in the mRNA. When the ribosome sees the "stop" code, it ends the translation and the protein is complete. How a ribosome makes a protein Different Types of Proteins There are literally thousands of different types of proteins in our bodies.
Here are a few of the major groups and functions of proteins: Structural - Many proteins provide structure for our bodies. This includes collagen which is found in cartilage and tendons. Defensive - Proteins help protect us from diseases.
What Is the Role of RNA in Protein Synthesis?
They make up antibodies that fight off foreign invaders such as bacteria and other toxic substances. Transport - Proteins can help to carry essential nutrients around our bodies.
One example is hemoglobin which carries oxygen in our red blood cells.Proteins and Nucleic Acids
Catalysts - Some proteins, such as enzymes, act as catalysts to assist in chemical reactions. They help us to break up and digest our food so it can be used by our cells.
