Question

A single strand of mRNA is created by using DNA as a template. What is the correct sequence of events that occurs next during protein synthesis?

Responses

The mRNA combines with another strand to form double stranded RNA and then goes to a ribosome to make a protein

The mRNA leaves the nucleus to undergo translation into a protein at the mitochondria

The mRNA goes to a ribosome after leaving the nucleus where codons and anticodons match up to string together changes of amino acids

Answer 1

The correct sequence of events that occurs next during protein synthesis is that the mRNA goes to a ribosome after leaving the nucleus where codons and anticodons match up to string together chains of amino acids, ultimately forming a protein. The ribosome acts as the site of protein synthesis and reads the sequence of codons on the mRNA, each of which corresponds to a specific amino acid. Transfer RNAs (tRNAs) carrying the appropriate anticodon sequence then bring the corresponding amino acids to the ribosome, where they are linked together to form a growing peptide chain until the entire protein is complete. The completed protein may then undergo additional processing or folding before it can perform its cellular function.

Answer 2

The correct sequence of events for protein synthesis after mRNA is created is:

The mRNA goes to a ribosome after leaving the nucleus where codons and anticodons match up to string together changes of amino acids

The key steps are:

DNA is used as a template to create mRNA strands in the nucleus.

The mRNA then leaves the nucleus.

The mRNA goes to ribosomes in the cytoplasm.

At the ribosomes, the mRNA codons pair with tRNA anticodons to recruit amino acids.

The amino acids are strung together into a polypeptide chain.

The polypeptide chain then folds into a functional 3D protein.

The other options are incorrect:

The mRNA does not combine with another strand to form double stranded RNA. It remains single stranded.

The mRNA does not go to the golgi apparatus. It goes directly from the nucleus to ribosomes.

The proteins are not synthesized in the mitochondria. They are synthesized on ribosomes in the cytoplasm.

So in summary, the key stages after mRNA creation are: transcription to mRNA in nucleus → mRNA transport to cytoplasm → translation into proteins at ribosomes.
