How is the correct amino acid bound to its appropriate tRNA molecule?
ANSWER A IS WRONG
A. they are bound by the enzyme amino acyl tRNA synthetase in the nucleus
B. they are bound by the enzyme amino acyl tRNA synthetase in the cytoplasm
C. they are linked during modification in the rough ER
D. they are connected by RNA polymerase in the nucleus

12. If an aminoacyl-tRNA synthetase attaches the wrong amino acid to a tRNA, what will happen? O The tRNA won't fold into the correct secondary structure. O The tRNA will be rejected by the ribosome. O The wrong amino acid will be added to the polypeptide, but it will be removed during proofreading. O The wrong amino acid will be added to the polypeptide.

During elongation of proteins during protein synthesis tRNA with the amino acid that matches its anticodon binds to the codon on the mRNA. each new amino acid is first transferred to the anticodon of the tRNA. anticodons on the ribosomes recognize the codons on the mRNA and attach the correct amino acids. ribosomes move along the DNA. RNA polymerase II uses the codons on the mRNA to polymerize the protein.
