Question
In which step does the polypeptide continue to grow as amino acids are added to the chain?
- Transcription
- Elongation
- Termination
- Initiation
Solution
The polypeptide chain continues to grow during the Elongation step.
Explanation:
- Transcription is the process in which the DNA sequence is copied into messenger RNA (mRNA).
- Elongation is the phase where ribosomes move along the mRNA, adding amino acids one by one to the growing polypeptide chain, based on the sequence of codons in the mRNA.
- Termination occurs when the ribosome reaches a stop codon, signaling the end of protein synthesis.
- Initiation is the beginning stage where the ribosome assembles around the mRNA and the first transfer RNA (tRNA) molecule.
Thus, the correct answer is Elongation.
