Codons and Anticodons

ATCAGTGAT A codon is a sequence of three nucleotides that code for an amino acid. If the DNA sequence shown here goes through transcription and translation, how many amino acids will result from this sequence?

• 5
• 4
• 2
• 3

Given the following sequence of mRNA, what series of amino acids are coded for?
mRNA: CUCAAGUGCUUC

• Ser-Tyr-Arg-Gly

In an mRNA strand, the codon AAG codes for the amino acid , while GUU codes for the amino acid .

• Lysine (Lys), Valine (Val)
• Lysine (Lys), Leucine (Leu)
• Asparagine (Asn), Valine (Val)
• Arginine (Arg), Glutamine (Glu)
