Protein Synthesis

Protein Synthesis is the creation of proteins from amino acids inside a cell. There are many steps to protein synthesis, which begins in the nucleus and ultimately finishes in the ribosomes.

Above is a diagram showing the process of Protein Synthesis. But I'll go more into detail on the process.

First the DNA, inside the nucleus, produces an identical copy of itself in a process called replication. This copy is created specifically for mRNA to read. The mRNA reads the bases of the DNA and codes them into RNA in a process called transcription. It gives these RNA codons to tRNA, which exits the nucleus and takes them to the ribosomes to become proteins. Once it reaches the ribosomes, rRNA appears and reads these codons, turning them into the amino acids that they code for. These amino acids join together to build specific kinds of proteins that the cell needs.

I did not know anything about Protein synthesis before this class. I didn't even know it existed or that cells did it. This class has taught me a lot about protein synthesis.
