Question

1. think and discuss: why is it important that the cells dna is duplicated before cell division? what would happen if the dna was not duplicated?

Explanation:

DNA carries genetic information. Duplication ensures each new cell gets a full set. Without duplication, new cells would lack genetic info. This could cause non - functioning cells or cell death.

Answer:

It is important for DNA to be duplicated before cell division because DNA contains the genetic instructions for the cell's functions. When a cell divides, each new cell (daughter cell) needs a complete set of these instructions to survive and function properly. If DNA was not duplicated:

• The daughter cells would receive only half (or an incomplete amount) of the genetic information.
• They would lack the necessary genes to carry out essential cellular processes like metabolism, growth, and responding to the environment.
• In most cases, such cells would not be able to function correctly and might die. In some rare cases (like in very simple cells or under specific experimental conditions), cells might show abnormal and non - viable characteristics.
