THE MOLECULAR BASIS OF INHERITANCE

DNA REPLICATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why does DNA need to replicate?
A
to pass genetic information on to new generations of cells
B
to create a new copy to replace the damaged original
Explanation: 

Detailed explanation-1: -Cells must replicate their DNA before they can divide. This ensures that each daughter cell gets a copy of the genome, and therefore, successful inheritance of genetic traits.

Detailed explanation-2: -Due to the process of DNA replication, each daughter cell gets an equal amount of DNA. The process of DNA replication helps in the inheritance process by transfer of the genetic material from one generation to another. Therefore it is required for the growth, repair, and regeneration of tissues in living organisms.

Detailed explanation-3: -Genetic information is passed from generation to generation through inherited units of chemical information (in most cases, genes). Organisms produce other similar organisms through sexual reproduction, which allows the line of genetic material to be maintained and generations to be linked.
