Grade 10 Protein Synthesis Worksheet

Protein Synthesis Worksheet

Read each question carefully and answer to the best of your ability. Refer to your notes and textbook if needed.

1. Observe the diagram below, which illustrates the process of protein synthesis. Label the following components: mRNA, tRNA, ribosome, amino acid, nucleus, and cytoplasm. Then, briefly explain the two main stages of protein synthesis.

Explanation of Stages:

2. Which of the following molecules carries the genetic code from the nucleus to the ribosome?

3. The process of converting the mRNA sequence into an amino acid sequence is called:

4. The process of protein synthesis begins in the   with  , where a molecule of mRNA is created from a DNA template.

5. Each three-nucleotide sequence on mRNA is called a  , which codes for a specific  .

6.   molecules bring the correct amino acids to the ribosome during  .

7. Ribosomes are responsible for both transcription and translation.

8. DNA leaves the nucleus to participate directly in translation.

Match the term with its correct description.

13. Describe the role of RNA polymerase in the process of transcription.

14. Explain why protein synthesis is a crucial process for all living organisms.
