The Evolution of Eukaryotic Cells from Prokaryotic Cells

DNA- Deoxyribonucleic acid (DNA), a self-replicating material present in nearly all living organisms, is the acid that carries genetic information. RNA- Ribonucleic acid (RNA), is an acid that is present in all living cells, it’s main role is to act as messenger and carry instructions from DNA fro controlling the synthesis of proteins.

What are Eukaryotic Cells and Eukaryotic Organisms?

A eukaryotic cell is a cell that contains complex organelles like nuclei or mitochondria enclosed within a membrane and eukaryotic organisms are organisms that are made up of eukaryotic cells like us, humans.

What are Prokaryotic Cells and Prokaryotic Organisms?

Prokaryotic cells are cells that lack nuclei and other organelles within the cell membrane; they have strands of DNA and RNA in them instead of nuclei. However, prokaryotic cells are not as simple as they look or sound. “The DNA in the prokaryotic cell unzips to make a molecule of RNA, and then the RNA makes proteins that help rebuild the cell wall. Sometimes the DNA reproduces itself, and then the new DNA molecule clings to the cell wall while the cell divides to make a new cell with the new DNA inside it. Prokaryote cells also have a little string of protein molecules that hangs off the end like a tail, called a flagellum. The cell can move this flagellum by pushing protons or energy at it, and it can use the flagellum to move itself from one place to another.”
