Some characteristics of dna are shared between all living organisms, whereas other characteristics of dna differ between organisms. classify dna characteristics as either being a universal attribute of dna or an attribute of dna that is unique to particular individuals or species. nucleotides a, c,g, t; triplet; dna sequence; size of genome; code for amino acids.

Universal DNA attribute: nucleotides A,C,G,T; triplet; code for amino acids.

DNA attribute unique to particular individual: DNA sequence; size of genome.

Explanation:

As all the organisms on the earth are evolved from a single organism or individual, therefore, all the organism on the earth share some universal attributes like nucleotide that are used to make DNA are same in all the individuals as all use A, T, G, C nucleotide to make DNA.

Triplet codon for a particular amino acid is also universal so a triplet codon UUU codes for phenylalanine in all the individual present on earth. Due to evolution organisms generated some difference in their genome like genome sequence in almost every individual is different and genome size also differ between organisms. So DNA sequence and size of the genome are unique to a particular individual.
