Answer Keys for Common Webquest Questions
Question 1: What is the role of mRNA in protein synthesis?
Answer: The role of mRNA is to carry the genetic information transcribed from DNA to the
ribosome, where it serves as a template for assembling amino acids into a protein.
Question 2: Describe the function of tRNA during translation.
Answer: tRNA's function is to transfer specific amino acids to the ribosome and match its
anticodon with the mRNA codon to ensure the correct sequence of amino acids in the
protein.
Question 3: What are codons and anticodons? How do they interact?
Answer: Codons are sequences of three nucleotides on mRNA that specify particular
amino acids. Anticodons are complementary three-nucleotide sequences on tRNA that pair
with the codons during translation to ensure accurate amino acid placement.
Question 4: What is the significance of the genetic code being universal?
Answer: The universality of the genetic code means that nearly all organisms use the
same codon-to-amino acid assignments, which highlights the shared evolutionary origin
and allows for genetic engineering across species.

Question 5: How does mutation affect protein synthesis?
Answer: Mutations can alter the DNA sequence, leading to changes in mRNA codons,
which may result in the production of dysfunctional or altered proteins, potentially causing
genetic disorders or variations.

QuestionAnswer
What is the main purpose of
protein synthesis in cells?
The main purpose of protein synthesis is to produce
proteins, which are essential for cell structure and
function, including enzymes, hormones, and other vital
molecules.
What are the two main
processes involved in protein
synthesis?
The two main processes are transcription, where DNA is
transcribed into mRNA, and translation, where mRNA is
translated into a protein.
Where does transcription
occur in the cell?
Transcription occurs in the nucleus of eukaryotic cells.
4
What role does mRNA play in
protein synthesis?
mRNA acts as a messenger that carries the genetic
code from DNA in the nucleus to the ribosomes in the
cytoplasm, where proteins are assembled.
What is the function of tRNA
during translation?
tRNA transports specific amino acids to the ribosome
and matches its anticodon to the mRNA codon to
ensure the correct amino acids are added to the
growing protein chain.
How does the sequence of
nucleotides in DNA determine
the sequence of amino acids
in a protein?
The sequence of nucleotides in DNA is transcribed into
mRNA, and the sequence of codons in mRNA
determines the order of amino acids during translation,
ultimately shaping the protein's structure.
Why is understanding protein
synthesis important in biology
and medicine?
Understanding protein synthesis is crucial because it
helps explain how genes direct cellular functions, and it
is essential for developing treatments for genetic
disorders, diseases, and for biotechnological
applications like gene therapy.
