A photo series

photo #1- DNA

What is this? This is the DNA is the cell.

Where is this located? The DNA is located in the nucleus.

What is the name of this shape? Double helix.

What are the components? The components are A (Adenine), which goes with U (Uracil), and G (Guanine), which goes with C (Cytosine).

photo #2- unzipped DNA

What is happening here, in reality? In this photo the DNA is beginning to unzip.

Where does this happen? This happens in the Nucleus.

What is the purpose of this step? In this step the ladder must be unzipped because cells only copy one side of the DNA ladder

photo #3- mRNA strand

What is the name of this process? The name of this process is transcription.

What is happening here, in reality? In reality the chemical bases of mRNA are also attached to a backbone as in DNA.

How are DNA and mRNA different? DNA uses T, and mRNA uses U.

Where is this happening? This is happening in the Nucleus.

photo #4- begining to create a protein

What are we looking at? We are looking at a strand of mRNA in the cell.

Where does this molecule travel to and from? this molecule travels to the cytoplasm from the nucleus

photo #5- continuing to create the protein amino acids

What is the name of this process? Translation step 2.

What is happening here, in reality? In reality each group of 3 is a "code" for a particular amino acid.

Where is this happening? This is happening in cytoplasm in the cell.

What do the colored circles represent? the colored circles represent the amino acids.

How does the code work? The code is translated into a particular amino acid that helps build the cell

photo #6- finishing off the protien

What does this completed structure represent? this represents a completed protein

What would happen to it now? it would either get released into various parts of the cell cytoplasm or released to the outside of the cell
