The information that determines our traits is stored in the sequence of nucleotides in our DNA. The DNA molecule is made up of two strands that are held together by chemical bonds between the nucleotides. Each strand is made up of a chain of nucleotides, which are the building blocks of DNA. The order of these nucleotides, or the sequence, contains the genetic information that determines our traits.
The four types of nucleotides in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). These nucleotides are arranged in specific sequences, or codons, that specify the sequence of amino acids in proteins. Proteins are the building blocks of the body and play a central role in many of our physical and biochemical traits.
Therefore, it is the sequence of nucleotides in the DNA molecule that holds the information that determines our traits.
