Hello everyone, today we will be learning about protein synthesis. Protein synthesis is an important process that happens in every living organism. Proteins play a crucial role in building and maintaining the structure of a cell and carrying out various functions in the body.

What is Protein Synthesis?

Protein synthesis is the process of creating proteins from amino acids. This process occurs in two major stages: transcription and translation.


During transcription, DNA is copied into RNA. This happens in the nucleus of the cell. The RNA molecule carries "instructions" from the DNA to the ribosomes in the cytoplasm.


During translation, the RNA molecule is used to build a protein. This happens in the ribosomes. The ribosomes use the information from the RNA molecule to string together amino acids.

Steps in Protein Synthesis

Let's look at the steps involved in protein synthesis in more detail:

  1. Transcription

    • DNA molecule unzips, and RNA polymerase binds to one of the DNA strands.
    • RNA polymerase creates a complimentary RNA strand by reading the DNA code.
    • The RNA molecule detaches from the DNA and leaves the nucleus.
  2. Translation

    • The ribosome binds to the RNA molecule and reads the genetic code.
    • As the ribosome "reads" the RNA code, tRNA (transfer RNA) brings amino acids to the ribosome.
    • The ribosome links the amino acids together using peptide bonds to form a protein.

Importance of Protein Synthesis

Protein synthesis is a crucial process because proteins perform a variety of important functions in the body. Proteins are involved in:


In conclusion, protein synthesis is a vital process in the body. It involves transcription and translation, which work together to build proteins from amino acids. Proteins are essential for many functions in the body.


Please research and write a short essay on the function of proteins in the body. Additionally, create a diagram showing the steps involved in protein synthesis.
