Which of the following are made of eukaryotic cells a. e. coli b. muscle c. salmonella d. carrot

There are two types of cells found in nature, eukaryotic cell and the prokaryotic cell. The Eukaryotic cells are those cells, which have a well defined nucleus and membrane bound organelles. The prokaryotic cells do not have nucleus. The bacteria are the prokaryotic cells, there genetic material is present in the cytoplasm.

The E.coli and Salmonella are the bacterial cells, hence, they are prokaryotic cells.

The plants and the animals are made up of eukaryotic cells, hence, carrot and muscle cells are the eukaryotic cells.

So, the correct answers are options b. muscle and d. carrot.

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.'
