Question
question 1
biologists believe the process of mitosis evolved from binary fission. what are the similarities between these two processes?
in both processes, the dna that is being separated is attached to a membrane.
both processes include dna segregation.
both processes necessarily involve the separation of more than one piece of dna
dna must be tightly packaged into chromosomes before either process can begin.
In binary fission and mitosis, DNA needs to be separated and distributed to new cells. This involves DNA segregation in both processes. In binary fission of prokaryotes, the circular DNA attaches to the cell membrane during separation. In mitosis of eukaryotes, chromosomes separate but not always attached to a membrane in the same way as in binary - fission. Prokaryotes don't package DNA into chromosomes like eukaryotes in mitosis. And binary fission can involve a single piece of circular DNA.
