In most eukaryotes mitochondria replicate and fuse all the time; they don't have to replicate during the cell cycle.
In cells that have only one mitochondrion (like kinetoplastids) mitochondria follow the same replication process as the cells (G1, S, G2 and M phases).

Why is DNA present in mitochondria of a cell?
It is thought that the mitochondria were once microorganisms and so have their own DNA.
Does mitochondria replace itself in the cell?
They have their own DNA.So they can self replicate.
During which period of time does a eukaryotic cell replicate its DNA?
The S phase of the cell cycle
How is replication a part of the cell cycle?
It is the main purpose of the cell cycle, to replicate the cell. the DNA is replicated, along with everything else, to form a new identical cell.
How can mutations or alterations in the mtDNA be inherited?
Mitochondria are able to replicate by themselves. When mitochondria replicate, a copy of the mitochondrial DNA is present in the daughter mitochondria as well. This is how they are passed on. Edit: Mitochondrial DNA is passed on maternally (ie the mito. that replicate in a new organism are derived from the mother/egg).
Which cellular organelles replicate in the G1 phase of the cell cycle?
Organelles such as the mitochondria and the chloroplasts replicated in the G1 phase of the cell cycle. This is so that when the cell divides, no parts are lost.

When does the mitochondria replicate?
It replicates in the cell division.It occurs in G1 phase.
What part does cell cycle does cell replicate its DNA?
mitosis
How do organelles replicate?
Replication is when the process by which a cell makes a copy of the DNA in its nucleus. Mitosis is the stage of the cell cycle during which the cell's nucleus divides into two new nuclei and one copy of the DNA is distributed into each daughter cell.
When does DNA replicate during the cell cycle?
During synthesis stage of the cell cycle
What phase of mitosis are mitochondria made?
It all depends on which organism you are talking about and there is no set phase.In many single-celled eukaryotes, their growth and division is linked to the cell cycle.In single cell algae. the only chloroplast and then the only mitochondrion divide before the nucleus undergoes mitosis and before cytokinesis.In other eukaryotes (in mammals for example), mitochondria may replicate their DNA and divide mainly in response to the energy needs of the cell, rather than in phase with the cell cycle. If it does replicate with the cell cycle, it can occur during the S phase of the mitotic cycle and even through out the mitotic cycle.It all depends on which organism you are talking about and there is no set phase.In many single-celled eukaryotes, their growth and division is linked to the cell cycle.In single cell algae. the only chloroplast and then the only mitochondrion divide before the nucleus undergoes mitosis and before cytokinesis.In other eukaryotes (in mammals for example), mitochondria may replicate their DNA and divide mainly in response to the energy needs of the cell, rather than in phase with the cell cycle.

A sentence using the word cell cycle?
The cell cycle is the process in which cells use to divide and replicate.
Where in the cell Krebs cycle occur?
Mitochondria
Phase of cell cycle when the organelles and chromosome replicate?
Interphase
Can mitochondria and chloroplasts reproduce within the cell?
Mitochondria produce lots of energy, infact they are known as the power houses of the the cell, however chloroplasts capture the duns energy and turn it into food, chloroplasts also split water and release oxygen
