Question

which statement best compares transcription and translation?
o trna pairs with complementary mrna in both transcription and translation.
o a peptide bond is created between amino acids in both transcription and translation.
o dna is transcribed into a complementary strand of mrna in translation but not transcription.
o a chain of amino acids linked by peptide bonds is formed in translation but not transcription.

Explanation:

• Transcription is the process of making mRNA from DNA.
• Translation is the process of making a polypeptide (chain of amino acids) from mRNA.
• tRNA pairs with mRNA only in translation.
• Peptide bonds are formed between amino acids only in translation.
• DNA is transcribed into mRNA in transcription, not in translation.

Answer:

D. A chain of amino acids linked by peptide bonds is formed in translation but not transcription.
