Question

What distinguishes archaea from animal cells? View Available Hint(s) What distinguishes archaea from animal cells? Archaea's RNA polymerase is unlike that of animal cells. Archaea have cell walls. Only animal cells associate DNA with histones. Archaea utilize methionine as the first amino acid during translation.

Answer 1

Answer & Explanation:

All archeas are single-celled organisms, and despite having prokaryotic cells, there are both similarities and differences between archaea and bacterial cells and also with eukaryotes.

Archaea have only one cell that has no nucleus or real organelles, and its cells have membranes composed of branched lipids, which greatly alter the structure of the archaeal cell membranes. In addition, the archaea have only one DNA strand (uniqueness).

Animal cells differ from archeas because they are multicellular (organisms with several cells), each one having a nucleus, and they also have specialized organelles.

In addition, animal cells have compounds called phospholipids in their membranes, which are unbranched lipids, and therefore do not cause major changes in the structures of their cells. Finally, animal cells have double-stranded DNA (complementary duplication).
