Understanding Protein Synthesis: From DNA to Protein Molecules

The video explains how DNA codes for proteins by arranging bases in sequences that correspond to specific amino acids. The process of protein synthesis begins in the nucleus, where a gene template is created and then moves to the ribosome. Carrier molecules bring amino acids to the ribosome, where they are assembled into a protein chain. The chain folds into a unique shape, allowing the protein to perform its function. Examples include enzymes, hormones, and structural proteins.

What determines the specific protein that is produced during protein synthesis?

• The order of bases in DNA

• The type of cell

• The number of amino acids

• The size of the ribosome

Where does the first stage of protein synthesis occur?

• In the ribosome

• In the nucleus

• In the cytoplasm

• In the mitochondria

What is the role of the ribosome in protein synthesis?

• To store DNA

• To replicate DNA

• To transport amino acids

• To synthesize proteins

How do carrier molecules contribute to protein synthesis?

• They bring amino acids to the ribosome

• They replicate DNA

• They break down proteins

• They fold proteins into their final shape

Which of the following is an example of a protein synthesized through this process?

• Starch

• Cholesterol

• Insulin

• Glucose
