Mitochondria and chloroplast have similar DNA, which is not evidence for the endosymbiotic origins of mitochondria and chloroplasts.
According to the endosymbiotic theory, a chloroplast and a mitochondria were the independent prokaryotes. Both can be ingested by a large prokaryote and resist digestion. As a result, they continued as endosymbionts and eventually lost some of their autonomic properties. They divide by binary fission, have their own genetic material, possess 70s ribosomes, and Both include their own transcriptional and translational machinery.
Therefore, considering endosymbiotic origin theory, Both Mitochondria and chloroplast have similar DNA is not a piece of evidence.

I think the correct answer from the choices listed above is option B. You can find methanogens in the human intestines. These organisms can work with or without oxygen. Too much of oxygen for them is toxic. They are obligate anaerobes.
The three steps in the process of dna replication are initiation, elongation, and termination.
Answer:
B
Explanation:
This is the answer that I think is correct
Answer:
The correct answer will be option-C.
Explanation:
The process of translation in prokaryotes is complex process and proceeds in three steps: initiation, elongation and termination.
1. Ribosomal subunits: 50S (5S and 23S subunit) and 30S (16S and proteins).
2. Initiation factors: IF1, IF-2 and IF-3 which help in the formation of assembly.
3 GTP: guanosine triphosphate as a source of energy.
4. Charged tRNA: with N-formylmethionine is the first amino acid.
5. mRNA: the RNA to be translated.
Since the option contains both 50S and 16S components of ribosome thus, Option-C is the correct answer.
