In prokaryotes, new mutations accumulate quickly in populations, while in eukaryotes, new mutations accumulate much more slowly.
musickatia [10]

In prokaryotes, new mutations accumulate quickly in populations, while in eukaryotes, new mutations accumulate much more slowly. The primary reasons for this are prokaryotes reproduce quickly and have vast populations.

<h2> Prokaryotes V/S Eukaryotes</h2><h3>Prokaryotes</h3>

Prokaryotes are organisms consisting of cells that don't have cell nuclei or any organelles that are enclosed in membranes. It follows that prokaryote's DNA is not contained within a nucleus.

The following components could be found in a normal prokaryotic cell:

  •  The membrane enclosing and guarding the cell is known as the cell wall.
  • All of the cell's internal components, excluding the nucleus, are called cytoplasm.
  • Some prokaryotic cells have filaments made of proteins called flagella and pili.
  • A nucleoid is a cell structure that resembles a nucleus and contains genetic material.
  • A plasmid is a little DNA molecule with independent reproduction.
<h3>Eukaryotes</h3>

Eukaryotes are organisms made up of cells with membrane-bound organelles and a nucleus that contains DNA in the form of chromosomes. Eukaryotic organisms can have several cells or just one cell. Eukaryotes make up all animal life. Protists, fungi, and plants are examples of additional eukaryotes.
