Answer:

The correct answer is -  1. The DNA unzips, and RNA bases match up along a strand.

Explanation:

The first stage of protein synthesis is transcription, which is the process that copies DNA sequences in a complementary sequence into the new mRNA molecule. In this stage, DNA molecule unwinds and unzip, and RNA molecule bind at a strand and elongate by adding new complementary bases with the help of RNA polymerase enzyme. Once the elongation of the RNA molecule ends the termination takes place and a new mRNA molecule that stores information to synthesis amino acid chin is produced successfully.

Thus, the correct answer is -  1. The DNA unzips, and RNA bases match up along a strand.
