Name three properties of the genetic code used by life on earth

[From: ] [author: ] [Date: 11-08-29] [Hit: ]
The 64 possible combinations of the three bases encode only 20 amino acids.Only methionine and tryptophan have single codons. This makes going from protein back through codons to find the specific DNA sequence very difficult.There are no ambiguous codons with alternate amino acids.Amino acids are grouped.Amino acids with similar physical properties tend to have similar codons.......
I'm not sure what my professor mean by this? Will these three be sufficient?

Genetic codes on earth uses codons consisting of 3 nucleotides.
Only tRNA could read nucleic information and protein information.
Genetic codes code for proteins (Amino acids)

The code is degenerate- Multiple codons result in the same amino acid. The 64 possible combinations of the three bases encode only 20 amino acids. Only methionine and tryptophan have single codons. This makes going from protein back through codons to find the specific DNA sequence very difficult.

There are no ambiguous codons with alternate amino acids. AUG codes for Metionine and never for another amino acid

Amino acids are grouped.
Amino acids with similar physical properties tend to have similar codons. Meaning when they belong to a single biosynthetic family, have codons are often contiguous in the genetic code.
Change in third codon position ‘wobble’ usually results in an unchanged protein
