Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types.
Answer:
What organelles are present in e-coli
Explanation:
"E-coli does not have many organelles because it is a prokaryote . They do not have a nucleolus or a nuclear membrane."
Membrane proteins can function as enzymes to speed up chemical reactions, act as receptors for specific molecules, or transport materials across the cell membrane. Carbohydrates, or sugars, are sometimes found attached to proteins or lipids on the outside of a cell membrane.
Tumor suppressor genes encode for proteins that inhibit or slow the progression of the cell cycle through a specific stage.they also encode for check point control proteins that arrests the cell cycle if the DNA is damaged or the chromosomes are abnormal. Mutation in the tumor suppressor genes that cause a loss or decreased function would lead to uncontrolled cell cycle leading to abnormal proliferation and the cell may become cancerous.
