Answer
Step Q utilizes peptidases to break down proteins into smaller peptides. Peptidases cleave peptide bonds, enabling the identification of smaller protein fragments that can be analyzed further.
Step 2

Answer
Step P is focused on the combination of amino acids to synthesize polypeptides. This process entails the formation of peptide bonds between amino acids, resulting in polypeptides that can be characterized in the study.

Answer
If children share the same parents, they receive the same genetic material, which leads to the synthesis of identical proteins unless mutations occur. This concept is essential in understanding inheritance and protein expression in organisms.
Step 4
the number of amino acids in the mixture containing all proteins is the same as the amino acids in the separated peptides.

Answer
The total number of amino acids remains constant because the mixture of all proteins, when separated into peptides, does not change the overall count of individual amino acids. This reflects the conservation of matter in biochemical processes.
