The answer is d. deletion.
If the DNA sequence is TTCACG, it is expected to be transcribed into AAGUGC.
But, it was transcribed into AAGGC. If we count nucleobases, a transcribed sequence has 5 nucleobases, while DNA sequence has 6 nucleobases. These means that deletion happened.
If insertion occurred, there will be 7 nucleobases in transcribed sequence. In substitution or translocation, the transcribed sequence will be the same size, but with different sequence than the DNA sequence.
B. Observing the nocturnal behavior of coyote populations
Mitosis is the part of the cell cycle where cell division makes 2 daughter cells that has the same amount and kind of chromosomes as the parent nucleus.
Phylogeny has to do with the history of the evolution of a species or a group, usually represented in the form of a phylogenetic tree. Since it studies evolution, it is only natural it could give us some kind of reliable information about the existence of life on Earth and how it all came to be.
