Answer: The correct answer is -
The new DNA molecule consists of one new strand and one old strand of DNA.
DNA replication is a process of formation of two molecules of DNA from a single DNA molecule (which is double stranded).
In this process, the two DNA strands of the original DNA are first separated so that the template strands are exposed.
Using the template strands, enzyme DNA polymerase adds nucleotides (in the direction 5' to 3') in a complementary manner-
For adenine, thymine, guanine, and cytosine in the template strand, thymine adenine, cytosine, and guanine are added respectively.
The new DNA molecule consists of one new strand and one old strand of DNA. That is why, it is also called semiconservative replication.
Thus, option third is the right answer.
The best topsoil will be found in the tropical region.
<h3>What are tropical regions?</h3>
They are regions of the world located within the two tropics - tropic of Capricorn and tropic of Cancer.
The region is characterized by adequate precipitation and relatively warm annual temperature. Thus, there is a high diversity of plants and animal species.
Tropical forests are known as the biodiversity hotspots of the world. This means that the soil is rich enough to support a diverse species of plants as compared to other regions of the world.
