Similarities of the Mitochondria & Nucleus
Similarities of the Mitochondria & Nucleus The mitochondria and nucleus are two organelles inside a cell that share many similarities. Both are made of two membranes. These membranes separate the inside of the organelle from the outside, but have protein channels that allow things to pass in and out. Both contain DNA material that carries genes that encode for proteins. Both have genes that make ribosomes, the machines that read the instructions in RNA to make protein. Two Membranes The mitochondria and nucleus are pouches whose walls are made of two membranes. A mitochondrion has an outer membrane and an inner membrane. A nucleus also has an outer membrane and an inner membrane. The two membranes of a mitochondrion serve different purposes. The inner membrane is where energy molecules are made. For the nucleus, its outer membrane is connected to the endoplasmic reticulum, another membranous organelle. The outer membrane of the nucleus also has ribosomes on it, similar to...
