Which of the following codons is most often recognized as the start codon for translation?
a. gua
b. aug
c. cug
d. uug
e. aag

The correct answer is B. AUG

Explanation:

In biology, translation refers to a process that occurs in cells as proteins are synthesized, translation occurs after transcription and implies the de-codification of messenger RNA that contains genetic information to a polypeptide (chain of amino acids). This process occurs as codons in mRNA attach to anticodons, the first codon in this process is an AUG codon that is attached to Methionine amino acid. This occurs in most cells including prokaryotes and eukaryotes although and just in very rare cases the translation begins with a different codon. Thus, the codon that is most often recognized as the start codon for translation is AUG.

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
