Over the past century, several scientists around the world have made the following observations: New mitochondria and plastids c

an only be generated by old mitochondria and plastids through a process similar to binary fission. Both mitochondria and plastids contain DNA that is similar in shape and size to that of bacteria. Mitochondria and plastids are surrounded by two or more membranes whose composition is similar to a prokaryotic cell membrane. Mitochondria and plastids are about the size as bacteria. These observations led scientists to conclude that

That this an endosymbiotic relation that has evolved over long time that has made the relationship now obligatory. These organelles represent formerly free-living prokaryotes taken one inside the other in endosymbiosis, around 1.5 billion years ago.

10. Translation.

<h3><u>Explanation:</u></h3>

Protein synthesis and the RNA synthesis is the total process that takes place together in each and every cell which is the Central Dogma theory.

In this theory, the RNAs are produced from the DNA by means of the process of transcription. In this process, the enzyme DNA dependent RNA polymerase acts as the primary DNA.

In the second step, the RNA produces the protein by the process of translation. This process involves the participation of each and every types of RNA like the rRNA, tRNA, and mRNA. These RNAs are all involved to form proteins by accumulation of amino acids and polymerizing them to form proteins.
