What occurs during the first stage of protein synthesis

1. The dna unzips, and rna bases match up along a strand.

2. Messenger rna moves out of the cell nucleus

3.transfer rna carries a specific amino acid to the ribosome.

4. Messenger rna attaches to a ribosome


Sagot :

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.
