A student is studying the amino acid sequence of a protein shared by four organisms. The student wants to know which organism is
most closely related to organism A. The student has data that shows the number of amino acid differences between organism A and each of the other organisms. Study the data in the chart. OrganismNumber of Difference in Amino Acid Sequence from Organism A B3 C5 D1 Which organism does this data suggest is most closely related to organism A?
Amino acids are the monomers of proteins and are linked together by the peptide bond. The protein is obtained from the RNA molecules by the process known as translation.
The amino acid sequence of the proteins can also be used to study the evolutionary relationship between the organisms and the closeness of teh organisms with each other. In the question it is give that organisms A and D has least difference ( 1 amino acid sequence difference) and more related with each other.
