The reduced the change of that matter
The domain Eukarya evolved from the unicellular organisms, and the proof of this can be derived from the endosymbiotic theory. According to this theory, the organelles, such as mitochondria and chloroplasts were previously free-living organisms. This is supported by the fact that the mitochondria and chloroplasts have their own DNA (deoxyribonucleic acid).
Hence, the answer is 'Option C - mitochondria and chloroplasts have their DNA.'
Answer:
Both have strong scientific support.

Answer:
The provided events can be classified as:
Initiation
- In prokaryotes, the Shine-Dalgarno sequence pairs with rRNA.
- In E. coli, mRNA binds to the 30S ribosomal subunit.
Elongation
- In E. coli, EF-Tu delivers an aminoacyl-tRNA to the ribosome
- Initiator tRNA enters the P site.
- In E. coli, EF-Tu hydrolyzes.
- Translocation occurs
Termination
- The ribosome has mRNA, an empty A site, and deacylated tRNA in the P site
Translation is the process by which polypeptide chain is synthesized based on the codon sequence of the mRNA (messenger ribonucleic acid).
It is divided into three stages:
Initiation: The small and large sub-units of the ribosome get assembled around the initiation codon. It forms three sites (A, P, and E site) for interaction tRNA and mRNA.
Elongation: Specific charged-tRNA enters from A site and transfers its amino acid to the growing polypeptide chain in P site. Uncharged tRNA exit from the E site. Ribosome moves or translocates to the next codon.
Termination: As soon as ribosome reaches the termination codon, it releases the newly synthesized polypeptide chain.
