Concept explainers
(a)
Interpretation : We have to comprehend the amino acid coded for AAG RNA codon.
Concept Introduction: A codon represents the sequence of three DNA or RNA
(b)
Interpretation : We have to comprehend the amino acid coded for the GUC 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 comprehend the amino acid coded for CGG 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 comprehend the amino acid coded for GCA 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.
