Question

Which is an accurate description of the processes used to turn the DNA code of a gene into a protein? A) Transfer RNA molecules carry the messenger RNA to the ribosome. B) Ribosomes go into the nucleus to read off the genes in the DNA. C) It takes one DNA base to code for three amino acids in a protein. D) Transfer RNA delivers specific amino acids to the ribosome, matching messenger RNA codons. Eliminate

Answer 1

Answer: The correct answer is- D) Transfer RNA delivers specific amino acids to the ribosome, matching messenger RNA codons.

DNA code of a gene is first converted into mRNA ( messenger RNA) through a process called transcription ( occurs in nucleus of eukaryotes and cytoplasm of prokaryotes). mRNA is then converted into protein through a process called translation ( occurs in the cytoplasm of cell).

During the process of translation, tRNA ( transfer RNA) delivers specific amino acid to the ribosome that matches with the codons ( sequence of three nucleotides in mRNA).

As a result, a long chain of amino acid is assembled, resulting in protein synthesis.

Answer 2

Transfer RNA delivers specific amino acids to the ribosome matching messenger RNA codons. :)
