Mrs. hines is grading her students' biology exams. question 3 asks students to circle the answers that classify a cell as a prokaryote. one student's exam has the following answers circled: has genetic material found within a nucleus has cytoplasm has a cell membrane why should mrs. hines mark the student's answer incorrect? the student's answers are correct, and mrs. hines made a mistake. prokaryotes do not have a nucleus. only eukaryotes have cytoplasm. prokaryotes do not have a cell membrane.

The correct answer is B. Prokaryotes do not have a nucleus.

Explanation:

In biology, the Prokaryotes along with the Eukorytopes are types of cells. In the case of the Prokaryotes these cells are found in bacteria and similar organisms different to Eukaryotes, Prokatyoes do not have a nucleus, lysosomes or Golgi complex. But they have cell walls which are only found in certain Eukorayotes cells and as most cells they Prokaryotes also have cytoplasm. This implies in the case presented the student should not have selected "has genetic material found within a nucleus" as a feature that identifies a cell as prokaryote as these do not have a nucleus and therefore the reason Mrs. Hines should mark the student's answer incorrect is Prokaryotes do not have a nucleus.

answer; /// i do believe its (heredity); good luck

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.'
