Which of the following is a codon that codes for the same amino acid as the codon AGC? UCA
TCG
GGT
GAC

UGA

Explanation:

There are 64 different codons in the genetic code and the below tables; most specify an amino acid.[7] Three sequences called stop codons, UAG, UGA, and UAA,[note 1] do not code for an amino acid but instead signal the release of the nascent polypeptide from the ribosome.[8] In the standard code, the sequence AUG—read as methionine—can serve as a start codon and, along with sequences such as an initiation factor, initiates translation.[3][9][10] In rare instances, start codons in the standard code may also include GUG or UUG; these codons normally represent valine and leucine, respectively, but as start codons they are translated as methionine or formylmethionine.[3][10]

the answer is: they occur when the sun, moon, and earth are aligned. in spite of their name, these tides occur twice a year in the spring and fall.
