Protein Synthesis Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

What are proteins made of and how many amino acids are there in humans?

Proteins are made up of long chains of amino acids. There are 20 different naturally occurring amino acids in humans.

How does the order of bases in DNA affect protein production?

The order of bases in a gene determines the sequence of amino acids, which determines the shape and function of the protein.

What are the two stages of protein synthesis?

Transcription and translation.

What happens during transcription?

The base sequence of a DNA gene is transcribed into an mRNA molecule in the cell’s nucleus.

What happens during translation?

The mRNA is translated into an amino acid sequence (protein) on ribosomes in the cell’s cytoplasm.

What role does tRNA play in protein synthesis?

tRNA transports specific amino acids to the ribosome, where they are added to the growing polypeptide chain, matching anticodons with codons on the mRNA.
