Protein Synthesis: Put the Steps in Order!
What are the steps of protein synthesis?
Arrange the following steps of protein synthesis in the correct order:
1. DNA double helix unwinds.
2. mRNA transcribed.
3. mRNA binds to ribosome.
4. tRNA molecules pick up amino acids.
Put these steps in their proper sequence.
Final answer:
The correct order of the steps of protein synthesis is as follows:
- The DNA double helix unwinds.
- mRNA is transcribed from the DNA template.
- tRNA molecules pick up amino acids.
- mRNA binds to the ribosome.
Protein synthesis is a complex process that occurs in the cells of living organisms. It begins with the unwinding of the DNA double helix to expose the coding region. Then, mRNA is transcribed from the DNA template through a process called transcription.
The mRNA molecule carries the genetic information from the DNA to the ribosome, where protein synthesis takes place. The mRNA binds to the ribosome, providing the template for the assembly of amino acids in the correct sequence. Meanwhile, tRNA molecules, which are specific to each amino acid, pick up their respective amino acids and bring them to the ribosome.
The ribosome facilitates the formation of peptide bonds between adjacent amino acids, ultimately leading to the synthesis of a protein chain according to the genetic code carried by the mRNA.
The correct sequence of steps in protein synthesis is crucial for the proper formation of proteins that are essential for the functioning of living organisms. Understanding these steps helps us appreciate the complexity and beauty of biological processes.
