Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is anti-codon?
A
This enzyme creates a polymer of DNA
B
This enzyme unwinds the DNA double helix
C
This is a set of 3 nucleotides on tRNAIf mRNA reads AUG, this will read UACThis forms hydrogen bonds with mRNA in the ribosome
Explanation: 

Detailed explanation-1: -anticodon – a sequence of three nucleotides on a tRNA molecule that bond to a complementary sequence on an mRNA molecule. The anticodon sequence determines the amino acid that the tRNA carries.

Detailed explanation-2: -A codon is a three-nucleotide or triplet sequence found on mRNA that codes for a certain amino acid during translation. The anticodon is a three-nucleotide sequence found on tRNA that binds to the corresponding mRNA sequence. The amino acid transported by the tRNA molecule is determined by the anticodon sequence.

Detailed explanation-3: -Anticodon An anticodon is a trinucleotide sequence located at one end of a transfer RNA (tRNA) molecule, which is complementary to a corresponding codon in a messenger RNA (mRNA) sequence.

Detailed explanation-4: -Methionine: the mRNA codon is AUG, and the tRNA anticodon is UAC.

Detailed explanation-5: -Answer and Explanation: The answer is aspartic acid. The translation is associated with mRNA and tRNA. The genetic code sequence of mRNA runs from 5’ to 3’.
