The body makes its own supply of this lipid, which has a ring structure and is part of every cell membrane.

If the statement is asking whether it is true or false, the answer is true. The body can make its own lipid because of the food that we eat and also because it is found in the body where it is located in the tissues and the cells.

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.'
