In the protein synthesis STEM case study, your patient Lucy was suffering from an immunodeficiency syndrome. What was the cause of her illness?

answer; ///(b) it is composed of four protein chains and four heme groups;

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link:

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
