Detailed explanation-1: -Most biologists implicitly define an individual organism as “one genome in one body.” This definition is based on physiological and genetic criteria, but it is problematic for colonial organisms.
Detailed explanation-2: -What does the order of the nitrogen bases determine? The order of the nitrogen bases determines which amino acids are made.
Detailed explanation-3: -The sequence of bases in a portion of a DNA molecule, called a gene, carries the instructions needed to assemble a protein.
Detailed explanation-4: -The sequence of basis on the DNA molecule is what directs the sequence of amino acids in the protein molecule-that’s how it all links together! So, the sequence of bases in DNA codes for the sequence of amino acids of a protein.
