The cell might not have enough of CYTOSINE to replicate its DNA.

WHAT IS DNA REPLICATION?

  • DNA replication is the process by which a cell makes a duplicate copy of its genetic material (DNA). Every cell must undergo DNA replication before it can divide.

COMPONENTS OF DNA:

  • DNA stands for deoxyribonucleic acid. It is a nucleic acid responsible for storing genetic information in living cells. DNA is made up of nucleotides, which in turn is composed of a deoxyribose sugar, phosphate group and nitrogenous bases.

  • The four nitrogenous bases that DNA contains are: Adenine, Cytosine, Guanine and Thymine.

Therefore, if the onion cells in this question seem only to be copying part of the DNA and stopping, it is probably due to insufficient nitrogenous base in DNA, which is CYTOSINE.
