Which one of the following statements is true regarding archaea? archaea are similar to eukaryotic cells in that they have introns in their dna. archaea are similar to eukaryotes in that they are multicellular organisms. archaea are similar to eukaryotes in that both are found in hostile environments. archaea are similar to eukaryotes in that they both have membrane-bound organelles, including a nucleus.

Option (1).

Explanation:

Three domains of life are eukarya, bacteria and archaea. Archaea are more closely related to eukarya than prokarya. Archaea and bacteria lacks well defined nuclear envelope.

Archaea share most of their characteristics with the eukarya. They have introns in their DNA sequences as similar to the eukaryotes. These introns shows the evolutionary relationship between the eukaryotes and the archaea. Apart from introns they also show similar characteristics like histone proteins.

Thus, the correct answer is option (1).

relationships play a major role in a human's emotional and mental wellbeing. healthy relationships with the people around you are even linked to a smaller production of cortisol, a stress hormone.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
