Question

What is unique to DNA alone?
A. Denaturation and Renaturation
B. Polymer complex
C. Replication
D. Resistance to temperature change

Answer 1

Hint: Every cell in humans has the same DNA that replicates itself and gets transferred to the progeny cells. DNA is a highly specialized and complex part of an individual. It consists of 2 strands that are interlocked to each other and form a shape called a double helix. Its double-helical structure plays an important role in replication.

Complete Answer:
As we know that DNA is Deoxyribonucleic acid and it is a chemical structure that carries the genetic information of human beings from one generation to another generation. We should note that DNA consists of 2 strands that are interlocked to each other and form a shape called a double helix. The double-helical structure of DNA was given by Watson and Crick. This double helix is held together by a hydrogen bond between nitrogenous bases and other strands. Every individual has very unique DNA that does not completely match even to their parents or siblings. This uniqueness of DNA helps to identify many criminals from a crime scene with help of blood and hair strand etc.

These are some really important points that tell us about the process of replication:
- Replication is a technique through which DNA makes it copy and transfer its component to a new cell.
- Other than replication several things are unique to DNA in fact DNA itself is very unique.
- Replication is important for the transfer of genetic information from parent cells to their offspring. This takes place in both somatic and germ cells.
- Germ cells take part in replication. Each strand of DNA serves as a template for the replication of another DNA.
- The separation of DNA strand forms a Y shape structure called a replication fork.
- An enzyme called DNA polymerase acts as a cataract and increases the reaction rate of replication.

Hence, the correct option is option C. Replication is the process unique to DNA alone.

Note: Replication is a technique through which DNA makes it copy and transfer its component to a new cell. Replication is important for the transfer of genetic information from parent cells to their offspring.
