After transcription, the new mRNA strand travels to the cytoplasm and over to the ___________ where the genetic code will be translated into amino acids.

nucleus

cell membrane

ribosomes

golgi bodies

Answers

The answer is C ribosomes

After transcription, the new mRNA strand travels to the cytoplasm and over to the RIBOSOMES where the genetic code will be translated into amino acids.

During gene transcription, a specific fragment of DNA called gene is used to produce a complementary messenger RNA (mRNA) sequence in the cell nucleus.

Subsequently, this mRNA travels to the cytoplasm where it is used as a template to synthesize a polypeptide chain in the ribosomes by a process called translation.

Ribosomes are protein factories that read the genetic code in the mRNA sequence (i.e., the codons of the mRNA) to translate it into the correct order of amino acids of the protein.

In conclusion, after transcription, the new mRNA strand travels to the cytoplasm and over to the RIBOSOMES where the genetic code will be translated into amino acids.
