To review:
The coordination of DNA (deoxyribonucleic acid) replication with cell wall septation.
Introduction:
DNA is designated as the genetic material that is found in almost all living organisms. It is first observed by Fredrich Miescher but its structure is described by James Watson and Francis Crick. It is a double helical structure that conveys biological information from parents to their offspring.
The process of
The termination site of DNA replication enhances the growth of dividing envelope partitions or septum. This septum grows in an inward direction and involves the sealing-off and formation of daughter cells. This process is known as cell separation. The growth of septum that separates the growing cells from one another is triggered after the completion of DNA replication of the termination site in the parent DNA.

- Which of the following best describes the difference between interphase and mitosis? a) During interphase, DNA has a loose structure that condenses during mitosis. b) During interphase, histones help compact DNA into chromosomes. And once mitosis starts, histones are destroyed. c) During interphase, DNA is tightly packed into chromosomes that uncoil once mitosis starts. d) During interphase, DNA is packed as chromosomes. And during mitosis, DNA is called chromatin. Please I need a surely answer and a quicker responsearrow_forward50. Cell motility involves the coordination of many events in the cell. In cells lacking flagella/cilia, which of the following are NOT required for cell motility? a) extension of actin filaments b) transmembrane proteins associating with extracellular matrix proteins in the underlying surface c) myosin-mediated contraction at the rear of the moving cell d) formation of a microtubule array in the leading edge of the cell e) formation of plasma membrane extensions such as pseudopodia or filopodiaarrow_forwardDefine chromatin.arrow_forward
- Why is it important that DNA replication take place before cell division? What would happen if cell division of a body cell took place without DNA replication, or when DNA replication was incomplete?arrow_forwardDefine the following: chromosome, centromere, centrosome, kinetochore, mitosis, cytokinesis, syncytium.arrow_forwardBriefly describe the molecular composition of the nucleoli and explain the function. As a cell begins the process of division, the chromosomes become shorter, thicker, and become visible under light microscope, explain what happens during that stage.arrow_forward
