Molecular clocks are models that use mutation rates in dna to measure evolutionary time. true or false

How can dna be useful in phylogeny? a. dna sequences are rearranged to predict how species could evolve in the future. b. dna sequences from different species can be compared, giving us more information about their evolutionary relationships. c. dna from every organism in a clade is sequenced to identify genetic mutations that have occurred. d. dna isn't useful in phylogeny, as morphological characteristics are used exclusively in phylogeny.
