What is the differences between prokaryotic and eukaryotic? explain your answer.

Prokaryotic cells lack some organelles while eukaryotic do not.
prokaryotic cells are often unicellular, while eukaryotics are often multicellular
prokaryotic cells do not have a nucleus, while eukaryotic cells have nucleus

Prokaryotic cells are known as the most primitive cells. They do not have a certain nucleus. The chromatin bodies are scattered in the cytoplasm. Eukaryotic cells, on the other hand, has a definite nucleus. Their chromatin bodies is covered with a nuclear membrane. They have a more organized structure that the former.

1.  The enzyme dicer cleaves dsRNA to form

small interfering RNA (siRNA).

2.  The siRNA binds to a special protein,  

which degrades one strand.

3. One strand of siRNA associates with the

protein to form an RNase complex.

4. The RNase complex binds to a specific

mRNA and degrades it.
