Question

write a prediction that answers the lab question, \how are proteins built using the information provided by a molecule of rna?\ remember, you are describing processes, so your prediction should include steps.

Explanation:

Step1: Initiation

The ribosome attaches to the mRNA (a type of RNA). The start codon (AUG) on the mRNA signals the beginning of translation.

Step2: Elongation

tRNA molecules, each carrying a specific amino - acid, match their anticodons to the codons on the mRNA. The ribosome moves along the mRNA, adding amino - acids one by one to form a polypeptide chain.

Step3: Termination

When the ribosome reaches a stop codon (UAA, UAG, or UGA) on the mRNA, translation stops. The polypeptide chain is released and may then fold into a functional protein.

Answer:

The ribosome first attaches to the mRNA at the start codon. tRNA molecules with amino - acids match to the mRNA codons during elongation. Finally, when a stop codon is reached, the polypeptide chain is released and can fold into a protein.
