Earlobes can be either attached or detached. The allele for attached earlobes is recessive (e), and the allele for detached earlobes is dominant (E). What
must be true if a boy is born with attached earlobes?

not sure if this is what you'r looking for eubacteria and archaebacteria

the missing space is phylum

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
