Can someone help me with this? 1. Why phylogenetic trees may construct using different regions of the DNA look different?
2. What regions of DNA should you use to compare organisms that are closely related?
3. What kind of genes should you use to compare organisms that are evolutionarily distant from each
other?
4. Can you think of reasons why, if you are studying more distantly related organisms, it is better to
compare amino acid sequences than DNA sequences?

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.'

linnaeus is the father of taxonomy, which is the system of classifying and naming organisms. one of his contributions was the development of a hierarchical system of classification of nature. today, this system includes eight taxa: domain, kingdom, phylum, class, order, family, genus, and species.
