Answer #1

Answer: Option C is correct
Explanation:
Arg is coded by 6 codons.
= CGU, CGC, CGG, CGA, AGA, and AGG

mRNA: tRNA
G: C or U
U: A or G
C: G
A: U

CGU/CGG can be recognized by a single tRNA anticodon
CGC/CGC can be recognized by a single tRNA anticodon
AGA can be recognized by a single tRNA anticodon
AGG can be recognized by a single tRNA anticodon

    Question 9: The genetic code is read in groups of three nucleotides, called codons, in mRNA that specifies for a particular amino acid. tRNA molecules act as the amino acid carriers that by correctly pairing with the codon on mRNA can deliver the correct amino acid to the ribosome during translation. At the tip of each tRNA molecule is a group of three nucleotides called an anticodon and at the other end is where the corresponding amino acid is attached...
