Answer: DNA
What is A? A three base sequence on a tRNA molecule that is complimentary to a codon on an mRNA.

While the specific nucleotide sequence of an mRNA specifies which amino acids are incorporated into the protein product of the gene from which the mRNA is transcribed the role of tRNA is to specify which sequence from the genetic code corresponds to which amino acid. The mRNA encodes a protein as a series of contiguous codons each of which is recognized by a particular tRNA. One end of the tRNA matches the genetic code in a three-nucleotide sequence called the

Mon May 25 2020 14:30:00 GMT-0400 (Eastern Daylight Time) · With respect to the mRNA the three sites are oriented 5’ to 3’ E-P-A because ribosomes move toward the 3′ end of mRNA . The A-site binds the incoming tRNA with the complementary codon on the mRNA . The P-site holds the tRNA with the growing polypeptide chain. The E-site holds the tRNA without its amino acid. When an aminoacyl- tRNA …

Each tRNA has an exposed sequence of three nucleotides known as the anticodon which are complementary in sequence to a specific codon that may be present in mRNA. For example the first codon encountered is the start codon …
