Question

Choose which characteristics are key features of the genetic code.



Three nucleotides encode an amino acid.

The code is degenerate.

The code has directionality.

The code is overlapping.

The code has punctuation.

Answer 1

1. Three nucleotides encode an amino acid. True, this is the definition of a codon, and the 64 combinations of amino acids allow for the encoding of 21 amino acids (note 2 would only have 16 combinations, which is not enough)
2. The code is degenerate. True, as there are 64 unique codons, and 21 unique amino acids, there have to be some codons that code for multiple amino acids, this also allows for some protection from mutations
3. The code has directionality. True, each amino acid has a 3' and 5' end.
4. The code is overlapping.False, each codon is separate from the previous, or else there would be correlation between adjacent amino acids
5. The code has punctuation. False, unless this is a metaphor, no :)

Hope this helps!
