What is the function of a codon?

• The function of a codon is to specify the amino acid or stop signal during protein synthesis.

• The function of a codon is to store genetic information.

• The function of a codon is to determine the shape of a protein.

• The function of a codon is to regulate gene expression.

What is the wobble concept in genetics?

• The wobble concept in genetics refers to the process of DNA repair in cells.

• The wobble concept in genetics refers to the ability of DNA to change its sequence during replication.

• The wobble concept in genetics refers to the flexibility of the base pairing rules between the third nucleotide of a codon and the corresponding nucleotide of an anticodon in tRNA.

• The wobble concept in genetics refers to the phenomenon of genetic mutations occurring only in certain regions of the genome.

How does the wobble concept affect the genetic code?

• The wobble concept has no effect on the genetic code.

• The wobble concept affects the genetic code by allowing certain tRNAs to recognize multiple codons.

• The wobble concept only affects RNA, not DNA.

• The wobble concept causes mutations in the genetic code.

What is a codon triplet?

• A codon triplet is a sequence of four nucleotides in DNA or RNA.

• A codon triplet is a sequence of amino acids in DNA or RNA.

• A codon triplet is a sequence of two nucleotides in DNA or RNA.

• A codon triplet is a sequence of three nucleotides in DNA or RNA.

How many codon triplets are there in the genetic code?

What is the function of a tRNA anti-codon?

• To prevent the binding of mRNA to the ribosome

• To catalyze the formation of peptide bonds

• To recognize and bind to the complementary codon on mRNA

• To transport amino acids to the ribosome
