According to the research, the correct option is during normal cell division. Vertical gene transfer is the transfer of dna during normal cell division.
<h3>What is
Vertical gene transfer?</h3>
It is the one that occurs when genes normally during cell division are transmitted within the same species, that is, from their ancestors from the parental gene to the progeny, as in the case of bacteria that occurs by binary fission when bacteria duplicate.
This transfer of genetic material from parent organisms to offspring is through reproduction within the same species.
Therefore, we can conclude that according to the research, the correct option is during normal cell division. Vertical gene transfer is the transfer of dna during normal cell division.

Answer:
Proterozoic Eon
Explanation:
The Proterozoic Eon is the most appropriate eon to indicate the geological age of this rock unit. This is because this rock presents fossils of the first multicellular and soft-bodied marine organisms and it was in the Eon Proterozoic that the first single-celled living organisms appeared.
The Proterozoic eon, as already mentioned above, is characterized by being the period of the land where the first multicellular marine organisms appeared. This period is divided into three ages: Paleoproterozoic Era (where eukaryotic beings arose), Mesoproterozoic Era and Neoproterozoic Era (where the first multicellular marine organisms arose).
In surgery yes. it would hurt without it and nobody would get surgery and surgeons would have no job. <span />
