HOW DO ORGANISMS REPRODUCE?
Organisms appear similar because their body designs are similar, which implies that the blueprints for these designs should also be similar. At its core, reproduction involves making copies of these blueprints.
1.DNA in Cells: In Class IX, we learned that chromosomes in the cell nucleus carry genetic information in the form of DNA (Deoxyribonucleic Acid). DNA is crucial for inheritance and contains the information required to produce proteins.
2.Protein Synthesis: The DNA in the cell nucleus acts as the information source for protein synthesis. Changes in DNA can lead to the production of different proteins, which can alter body designs.
1.Creation of DNA Copies: A fundamental event in reproduction is the creation of a DNA copy. Cells utilize chemical reactions to duplicate their DNA, resulting in two copies that need to be separated.
2.Separation of DNA Copies: Simply pushing a DNA copy out of the original cell would not suffice, as the new copy would lack the organized cellular structure necessary for life processes. Thus, DNA copying is accompanied by the creation of an additional cellular apparatus. The cell then divides, resulting in two cells, each containing a DNA copy and its own cellular apparatus.
