How Proteins are Made

Protein synthesis is the process where the DNA code is used to build specific proteins in the ribsomes.

What is the role of ribosomes in protein synthesis?

What is How Proteins are Made?

"Protein synthesis is a multi-step process including transcription (making a template) and translation (assembling amino acids) to create a protein."

Question 1

Where are genes found?

Question 2

Which is a concern about GM crops mentioned at GCSE?

Question 3

Which characteristic is most likely to be influenced by both genes and the environment?

Question 4

GCSE Biology: Where are genes found?

The DNA code in the nucleus is too large to leave, so a template (mRNA) is made.

The template leaves the nucleus and binds to a ribosome.

Carrier molecules (tRNA) bring specific amino acids to the ribosome in the correct order.

Exam Tip

Once the protein chain is complete, it folds into a unique shape to perform its function (e.g., as an enzyme).

The fastest way to improve your grade is to practise exam-style questions, identify your gaps, and focus only on what you don't know.
