Consider the recent phylogenetic tree of five different organisms. A phylogenetic tree is shown. The root of the tree is birds. The branches are crocodiles, bats, and insects.

Old classification systems based on physical characteristics would most likely disagree with the relationship between which two animals in the tree?
crocodiles and insects
bats and humans
birds and bats
humans and crocodiles

chromosomes carry the genetic information for organisms. also, chromatin is the thread like dna which is located in the nucleus of an organism.

carbon

explanation:

it would be heredity

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.'
