A
The sequence of bases in DNA
2
Q
What will the sequence of amino acids be like to organisms that are more closely related?
A
More similar
3
Q
What will a sequence of bases be like for organisms which are closely related?
A
Fewer base differences than distantly related species
4
Q
Why does comparing DNA or mRNA sequences provide more information than amino acid sequences?
A
Degeneracy of genetic code, introns in eukaryotic DNA
