Maybe this will help.....
DNA is short for deoxyribonucleic acid.
DNA is a long thin molecule made up of something called nucleotides. There are four different types of nucleotides: adenine, thymine, cytosine, and guanine.
They are usually represented by their first letter:
A- adenine
T- thymine
C - cytosine
G - guanine
Holding the nucleotides together is a backbone made of phosphate and deoxyribose. The nucleotides are sometimes referred to as "bases".
Our bodies have around 210 different types of cells. Each cell does a different job to help our body to function. There are blood cells, bone cells, and cells that make our muscles.
Cells get their instructions on what do to from DNA. DNA acts sort of like a computer program. The cell is the computer or the hardware and the DNA is the program or code.
The DNA code is held by the different letters of the nucleotides. As the cell "reads" the instructions on the DNA the different letters represent instructions. Every three letters makes up a word called a codon. A string of codons may look like this:
ATC TGA GGA AAT GAC CAG
Even though there are only four different letters, DNA molecules are thousands of letters long. This allows for billions and billions of different combinations.
Within each string of DNA are sets of instructions called genes. A gene tells a cell how to make a specific protein. Proteins are used by the cell to perform certain functions, to grow, and to survive
Although DNA looks like very thin long strings under a microscope, it turns out that DNA has a specific shape. This shape is called a double helix. On the outside of the double helix is the backbone which holds the DNA together. There are two sets of backbones that twist together. Between the backbones are the nucleotides represented by the letters A, T, C, and G. A different nucleotide connects to each backbone and then connects to another nucleotide in the center.
Only certain sets of nucleotides can fit together. You can think of them like puzzle pieces: A only connects with T and G only connects with C.
Biology for Kids: DNA and Genes
I'm quoting your original assertion, do keep up. You asserted...
"DNA separates species, not links them...It will also show we are not related to apes."
So you keep saying, now please present your evidence. Remember, you said...
"A conclusion is not valid without some supporting evidence."
So let's have it.
