Cell division occurs as a result of DNA copying. The separated DNA copies each have their own cellular apparatus, leading to the formation of two cells.

Separating the two copies of DNA is necessary because it is a fundamental step in reproduction. Simply pushing one copy out and keeping the other in the original cell would not be effective in generating new organisms with the same ...

A basic event in reproduction is the creation of a DNA copy, where cells use chemical reactions to build copies of their DNA.

DNA in the cell nucleus serves as the information source for making proteins. Different proteins are produced based on the information encoded in the DNA.

The information source for the inheritance of features is the DNA (Deoxyribo Nucleic Acid) molecules located in the chromosomes of the cell nucleus.
