Understand how the genetic code is translated into proteins during translation. Review the roles of mRNA, tRNA, and ribosomes with practice questions.
The genetic code is not ambiguous, meaning each codon specifies only one amino acid.
Ref: NCERT Class 12 Biology Chapter 5: Molecular Basis of Inheritance Genetic Code and Translation
tRNA has an anticodon region that pairs with the codon in mRNA during translation.
Ref: NCERT Class 12 Biology Chapter 5: Molecular Basis of Inheritance Genetic Code and Translation
Translation does not produce DNA from RNA; it converts mRNA into protein.
Ref: NCERT Class 12 Biology Chapter 5: Molecular Basis of Inheritance Genetic Code and Translation
The wobble hypothesis states that the third base of a codon can form non-standard base pairing, allowing one tRNA to recognize multiple codons.
Ref: NCERT Class 12 Biology Chapter 5: Molecular Basis of Inheritance Genetic Code and Translation
tRNA is not involved in DNA replication; it functions in translation by delivering amino acids to ribosomes.
Ref: NCERT Class 12 Biology Chapter 5: Molecular Basis of Inheritance Genetic Code and Translation
The genetic code is non-overlapping, meaning codons are read sequentially.
Ref: NCERT Class 12 Biology Chapter 5: Molecular Basis of Inheritance Genetic Code and Translation
rRNA (ribosomal RNA) functions as a catalytic molecule in translation, aiding in peptide bond formation.
Ref: NCERT Class 12 Biology Chapter 5: Molecular Basis of Inheritance Genetic Code and Translation
tRNA (transfer RNA) carries amino acids to the ribosome for protein synthesis during translation.
Ref: NCERT Class 12 Biology Chapter 5: Molecular Basis of Inheritance Genetic Code and Translation
Translation does not convert DNA into protein; it converts mRNA into protein.
Ref: NCERT Class 12 Biology Chapter 5: Molecular Basis of Inheritance Genetic Code and Translation
Aminoacyl-tRNA is required for elongation, delivering amino acids to the ribosome during translation.
Ref: NCERT Class 12 Biology Chapter 5: Molecular Basis of Inheritance Genetic Code and Translation
The anticodon loop of tRNA pairs with the codon of mRNA during translation.
Ref: NCERT Class 12 Biology Chapter 5: Molecular Basis of Inheritance Genetic Code and Translation
mRNA binds to the ribosome during translation initiation, providing the template for protein synthesis.
