Question

1. 1. uracil bonds with adenine. 2. complementary bonding between codon and anticodon. 3. dna unzips. 4. mrna joins with ribosome. the correct order of the above during protein synthesis is: 3,

Explanation:

Protein synthesis involves transcription and translation. Transcription starts with DNA unzipping (step 3). Then, during transcription, uracil (in RNA) bonds with adenine (step 1). After transcription, mRNA is formed. In translation, mRNA joins with ribosome (step 4). Then, there is complementary bonding between codon (on mRNA) and anticodon (on tRNA) (step 2).

Answer:

3, 1, 4, 2
