Biologists believe the process of mitosis evolved from binary fission.What are the similarities between these two processes?
A) In both processes, the DNA that is being separated is attached to a membrane.
B) Both processes necessarily involve the separation of more than one piece of DNA.
C) Both processes include DNA segregation.
D) DNA must be tightly packaged into chromosomes before either process can begin.

Question

Quizplus · Accepted Answer

Both mitosis and binary fission involve the segregation of DNA into separate compartments. This ensures that each daughter cell receives a complete set of genetic information. Option A is incorrect as in binary fission, DNA is attached to the cell membrane, while in mitosis, DNA is attached to spindle fibers. Option B is incorrect as binary fission involves the separation of one circular chromosome, while mitosis typically involves the separation of multiple linear chromosomes. Option D is incorrect as binary fission involves the replication and segregation of a single chromosome without the need for chromosome packaging. In mitosis, chromosomes must be tightly packaged into condensed structures before they can be segregated.
