Question at position 28 asks us to select all attributes of the genetic code from the list provided.
Option 1: 'Codons do not overlap' — This is true. In the standard genetic code, codons are read in a non-overlapping fashion during translation, with each codon representing a specific set of three nucleotides that corresponds to an amino acid or a stop signal.
Option 2: 'Every codon codes for an amino acid' — This is false. In addition to codons that specify amino acids, there are stop codons that terminate translation, so not every codon codes for an amino acid.
Option 3: 'Codons do overlap' — This is false. The reading frame is fixed so codons are read sequentially in non-overlapping triplets; overlapping reading frames are not how the canonical genetic code operates.
Option 4: 'The genetic code is not redundant' — This is false. The genetic code is degenerate or redundant, meaning multiple codons can encode the same amino acid.
Option 5: 'Every codon is used' — This is not strictly true. While many codons are used across organisms, there are codons that can be rare or unused in particular genes or organisms, and the presence of stop codons means not every codon corresponds to an amino acid.
Option 6: 'The genetic code is redundant' — This is true. Redundancy refers to multiple codons mapping to the same amino acid, which is a fundamental property of the code.

In summary, the statements that accurately describe the genetic code are that codons do not overlap and that the genetic code is redundant. The remaining options contain inaccuracies or are not universally true across all contexts.
