What is an fact about mitochondria?

Answer 1

Mitochondria hold DNA (likely because of evolutionary leftovers) and this DNA is directly inherited from the mother, meaning that it is an exact match to the mother's DNA. This type of DNA is used in forensics from time to time. Otherwise, mDNA serves no other purpose, and we likely won't even have it in a few million years. Even more interesting is the fact that Mitochondria contain DNA which is not ours! Put simply at some point in the distant past of human evolution; way in the past: at a point when we ourselves where very simple organisms. We formed an endosymbiotic relationship with a proto-bacteria for mutual benefit. This proto-bacteria - apparently related to the Rickettsia which still exits - then became permanent whithin every cell, providing energy but losing some independent features whilst retaining to this day it's own DNA. The Mitochondria have been described as "The Warp-Core of the cell" This is a more detailed explanation of what little is known about this fascinating yet generally unknown story of human development: That we are in fact a walking collection of symbiotic organisms!

Mitochondria have many features in common with prokaryotes. As a result, they are believed to be originally derived from endosymbiotic prokaryotes. A mitochondrion contains DNA, which is organized as several copies of a single, circular chromosome. This mitochondrial chromosome contains genes for redox proteins such as those of the respiratory chain. The CoRR Hypothesis proposes that this Co-location is required for Redox Regulation. The mitochondrial genome also codes for some RNAs of ribosomes, and the twenty-two tRNA's necessary for the translation of messenger RNAs into protein. The circular structure is also found in prokaryotes, and the similarity is extended by the fact that mitochondrial DNA is organized with a variant genetic code similar to that of Proteobacteria.[36] This suggests that their ancestor, the so-called proto-mitochondrion, was a member of the Proteobacteria.[36] In particular, the proto-mitochondrion was probably related to the rickettsia.[37] However, the exact relationship of the ancestor of mitochondria to the alpha-proteobacteria and whether the mitochondria was formed at the same time or after the nucleus, remains controversial.[38] The ribosomes coded for by the mitochondrial DNA are similar to those from bacteria in size and structure.[39] They closely resemble the bacterial 70S ribosome and not the 80S cytoplasmic ribosomes which are coded for by nuclear DNA. The endosymbiotic relationship of mitochondria with their host cells was popularized by Lynn Margulis.[40] The endosymbiotic hypothesis suggests that mitochondria descended from bacteria that somehow survived endocytosis by another cell, and became incorporated into the cytoplasm. The ability of these bacteria to conduct respiration in host cells that had relied on glycolysis and fermentation would have provided a considerable evolutionary advantage. In a similar manner, host cells with symbiotic bacteria capable of photosynthesis would also have had an advantage. The incorporation of symbiotes would have increased the number of environments in which the cells could survive. This symbiotic relationship probably developed 1.7[41]-2[42] billion years ago. A few groups of unicellular eukaryotes lack mitochondria: the microsporidians, metamonads, and archamoebae.[43] These groups appear as the most primitive eukaryotes on phylogenetic trees constructed using rRNA information, suggesting that they appeared before the origin of mitochondria. However, this is now known to be an artifact of long-branch attraction - they are derived groups and retain genes or organelles derived from mitochondria (e.g., mitosomes and hydrogenosomes).[1]

Answer 2

Richard Altmann was the first to discover the mitochondria. Though there are many who help discover it. It was discovered in 1898.

The inner section is called matrix. Cells that require a lot of energy to perform their function will have high numbers of Mitochondria. Mitochondria are found in plant and animals cells. They have their own small chromosome to make their own protein.

you are all losers

hey i love you

Is an organelle which includes cristae & matrix. Has ribosomes embedded in it which are used in the process if resperation.
They got their own DNA.They have 70s like bacteria

Answer 3

Double membraned.

Has DNA in it

Scientists speculate that it was once an individual protist but eventually evolved with other unicellular organisms into the cell that we know now

The bumps formed by the inner membrane is called the cristae

The inside of the mitochondria is called the matrix

The cell's "powerhouse" that converts nutrients and produces energy in the form of glucose through respiration and the calvin cycle

Answer 4

Mitochondria are known as the powerhouse of the cell because they are responsible for producing energy in the form of ATP through a process called cellular respiration. They have their own DNA and can self-replicate, which is why they are thought to have originated as independent bacteria that were engulfed by ancestral eukaryotic cells. Mitochondria play a crucial role in metabolism, regulation of cell cycle and cell growth, and cell signaling.

Answer 5

They have their own DNA. They have 70s ribosomes
