DNA is made up of nucleotides, which are small molecules made of two atoms of hydrogen and one atom of carbon. How do the four bases get paired up to form a nucleotide sequence?ĭNA is a molecule that carries the genetic instructions for making proteins. Each chromosome contains a small amount of DNA and carries the instructions for your body's growth and development.Ħ. Each cell in your body has 46 chromosomes made of 23 pairs of chromosomes each.ĥ. Adenine connects to guanine to make thymine, and cytosine connects to thymine to make DNA.Ĥ. The four bases of DNA are adenine, guanine, cytosine, and thymine.ģ. DNA (deoxyribonucleic acid) is the genetic material that makes up the chromosomes in cells.Ģ. What are the four bases of DNA: adenine, guanine, cytosine, and thymine?ġ. The sequence of these nucleotides determines the sequence of amino acids in a protein. Nucleotides are made up of one nitrogen atom and one carbon atom. This molecule is found in the nucleus of cells and consists of nucleotides. What is DNA and what does it stand for? DNA is a molecule that contains the genetic information of an organism. Introduction: What is DNA and what does it stand for? DNA is made up of four chemical bases, called nucleotides, which are hooked together by hydrogen bonds.
It is the genetic material that makes up the chromosomes in a cell and carries the instructions for making proteins.
