Concept explainers
(a)
Interpretation: We have to identify the amino acid coded for the CUG RNA codon.
Concept Introduction: A codon represents the sequence of three DNA or RNA
(b)
Interpretation: We have to identify the amino acid coded for UCC RNA codon.
Concept Introduction: A codon represents the sequence of three DNA or RNA nucleotides which are related to a specific amino acid. The mRNA codon carries the message specifying for an amino acid and tRNA transfers that amino acid to the growing protein chain.
(c)
Interpretation: We have to identify the amino acid coded for GGU RNA codon.
Concept Introduction: A codon represents the sequence of three DNA or RNA nucleotides which are related to a specific amino acid. The mRNA codon carries the message specifying for an amino acid and tRNA transfers that amino acid to the growing protein chain.
(d)
Interpretation: We have to identify the amino acid coded for AGG RNA codons.
Concept Introduction: A codon represents the sequence of three DNA or RNA nucleotides which are related to a specific amino acid. The mRNA codon carries the message specifying for an amino acid and tRNA transfers that amino acid to the growing protein chain.
