What is converting the genetic code into the language of proteins?
Ulleksa [173]


This is a process called transcription and translation.

Information to synthesize a particular protein is found in DNA in the cell nucleus. This information is copied (transcribed)  onto messenger RNA or mRNA in short. The copying process is called transcription.

mRNA then leaves the nucleus and enters the cytoplasm where it attaches to a ribosome. Transfer RNA or tRNA then begins to read (translate) the information on the attached mRNA. This is the process of translation.

tRNA then fetches amino acids that correspond to this information and brings them to the ribosome where they are linked together into a chain. This chain of amino acids is the primary structure of  the protein.

what is thought to be the correct sequence of these events, from earliest to most recent, in the evolution of life on earth? ori
Montano1993 [528]

The correct sequence of these events (origin of mitochondria, origin of multicellular eukaryotes, origin of chloroplasts, origin of cyanobacteria, origin of fungal-plant symbioses), from earliest to most recent, in the evolution of life on earth is 4, 3, 1, 2, 5.

The transition to eukaryotic cells seems to have taken place in the Proterozoic Era, around 1.2 to 1.5 billion years ago. Nevertheless, the latest genetic studies propose the divergence of eukaryotes from prokaryotes nearer to 2 billion years ago.

Margulis suggested the mechanism of endosymbiosis, to describe the origin of mitochondria as well as chloroplasts from persistent living prokaryotes. In accordance with this idea, a bigger prokaryote engulfed or enveloped a smaller prokaryote around 1.5 billion to 700 million years ago.
