• Eukaryotic cells

  Eukaryotic cells have telomeres at the end of their chromosomes which are long repeated sequences that serve to protect the information encoded in the chromosomes.

• Difference between plant/animal & eukaryotic/prokaryotic cells

  Eukaryotic DNA is complexed with proteins called "histones," and is organized into chromosomes; prokaryotic DNA is "naked," meaning that it has no histones associated with it, and it is not formed into chromosomes.

• Identical daughter cells through mitosis; prok vs eukaryotes

  greater complexity of the eukaryotic cell.

• Prokaryotic and eukaryotic cells

  The nucleus also contains the genetic material, DNA, organized in a characteristic number of chromosomes in each eukaryotic species.

• Identify what characteristic is required to form multi-cellular organism.

  Eukaryotic cells have their DNA organized into a number of discrete chromosomes, which are found inside a membrane-bounded nucleus. Cell division in eukaryotes involves a complex process called mitosis.

• DNA (deoxyribonucleic acid) is a nucleic acid

  DNA (deoxyribonucleic acid) is a nucleic acid containing the genetic information found in most organisms and which is the main component of chromosomes of eukaryotic organisms.

• Prokaryotic and eukaryotic cells

  - Animal, plant, fungi and protista cells are eukaryotic. - Eukaryotic cells contains one or more paired, linear chromosomes composed of deoxyribonucleic acid (DNA) associated with histone proteins.

• Comparison between eukaryotic and prokaryotic cells

  In prokaryotic cells, the DNA is linear and is compacted into chromosomes. DNA in eukaryotic cells is bound to DNA-binding proteins called histones. The prokaryotic DNA is usually circular.

• Why only eukaryotic cells evolved into multicellular orgs.

  They have chromosomes floating freely around the cell. The cell membrane is not static -- rather, it is a dynamic structure which is partly responsible for allowing eukaryotic cells to come together into multicellular organisms.
