THE DNA IS WHAT DEFINED US AND IT GATHER THE INFORMATION OF HOW WE LOOK LIKE.THE DNA IS WHAT IS USED TO KNOW WHAT COLOR OF EYES WE HAVE OR WHAT TYPE OF SKIN WE HAVE OR HOW IT WILL BE OUR TYPE OF HAIR. EVERY PIECE OF INFORMATION IS IN DIFERENT PARTS OF OUR DNA ,ALL THEESE SECTIONS ARE CALLED GENES.DNA IS FOR DEOXYRIBONUCLEIC ACID. THE DEOXYRIBONUCLEIC IS FOUND IN EVERY CELL THE CELLS ARE OF WHAT WE ARE FORM , THEY HAVE ORGANELLES LIKE US. DNA IS A MOLECULE MADE UP OF  nucleotides AND THERE ARE FOUR TYPES OF nucleotides:ADENINE,THYMINE,CYTOSINE,AND GUANINE. DNA is an essential molecule for life. It acts like a recipe holding the instructions telling our bodies how to develop and function.  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.

THE DNA

Imagen
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called  mitochondrial DNA  or mtDNA).  Mitochondria  are structures within cells that convert the energy from food into a form that cells can use. The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people. The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences. DNA bases pair up with each other, A with T and C wit...
