In the trna anticodon being matched at the ribosomes is aug what would be the matching mrna codon

UAC, and it encodes for the aminoacid Tyrosine.

Explanation:

Uracile pairs with Adenine via two hdrogen bonds, and Cytosine matches with Guanine with three hydrogen bonds in RNA molecules. In DNA molecules, there is not uracile, they contain Thymine instead, so Adenine pairs with Thymine by two hydrogen bonds.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
