The most prominent organelle that contains genetic material and is visible in most eukaryotic cells is the Nucleus.
<h3>What is Nucleus?</h3>
- The nucleus is a double membraned organelle found in all eukaryotic cells.
- It is the largest organelle, which functions as the control center of cellular activities and is the storehouse of the cell's DNA.
- The nucleus is dark, round, and surrounded by a nuclear membrane.
- Within the nucleus, there are tiny spherical bodies called the nucleolus. It also carries an essential structure called chromosomes.
- So the nucleus is the organelle that is visible and present in all eukaryotic cells.

Answer:
option B is correct that is meiosis 2
Explanation:
the two sister chromatids are separated from each other into two different cells during mitosis or during the second division of meiosis
The mitochondria is a double membraned organelle, the inner of these membranes is invaginated to form structures called cristae. The fluid inside is called the mitochondrial matrix. The mitochondria has a pivotal role in the creation of ATP in aerobic cellular respiration. Glycolysis occurs outside the mitochondria, producing pyruvate and ATP, the pyruvate endures the link reaction on its way into the mitochondrial matrix and turns into acetyl co enzyme A. This acetyl group is used in the matrix in what is called Krebs cycle, where the oxidation of acetyl groups is coupled with the reduction of hydrogen carriers. The products of Krebs cycle are then transported to the electron transport chain on the cristae where the reduced NADH and FADH are then oxidized. The remaining hydrogen electrons are transported down the chain where an oxygen molecule is reduced to water. Chemiosmosis also occurs at the electron transport chain, in which hydrogen protons move down the concentration gradient (from the inner mitochondrion membrane) through an ATP synthase where ATP is generated. The multiple folds inside the mitochondria which are the cristae, mean that there is plenty of surface area for cellular respirations to occur at.
