The DNA replication occurs by preparing a new strand of DNA that is based on the template strand only. So understanding the nitrogen base pairing is very essential for understanding DNA replication.
<h3><u>
Explanation:</u></h3>
DNA replication occurs prior to any type of cell division in all organisms. In case of humans, the DNA that is to be replicated needs to be de winded by means of decondensation of chromosomes into chromatin fibres and then to DNA fibres. Then there are enzymes like helicase and gyrase which helps in breaking the hydrogen bonds between two strands of DNA and to open it up for enzymes to get attached.
Then the enzyme DNA dependent DNA polymerase works on both the strands of DNA where it reads the mother DNA strand as a template and then brings deoxyribonucleotides complementary to the template strand and then polymerises it with the previous nucleotide to form a new DNA strand. Thus two DNA strands are produced which are again complementary to each other, leading to the production of a new daughter DNA. So, understanding the complementary base pairing is very essential to understand the DNA replication.

Answer:
Denitrification process occurs when the soil bacteria use nitrate for the respiration of oxygen in the air. These nitrates are converted to nitrogen gases.
<u>Explanation:
</u>
<em>The denitrification process mostly occurs in warm nature rapidly, wet soils with sufficient of nitrate. Denitrification process only occurs when the nitrate is present.</em> <em>The denitrification is in sewage treatment and it is beneficial process, the problem considered in agriculture farmers to increase their crop yields because they are applying nitrogen fertilizers to the land. </em>
<em>Denitrification process increases from cropland and it is responsible for increases the amount of nitrous oxide in the atmosphere. The denitrification process plays an important to recycling of nitrogen for healthy soil, microbial and for plant growth, and animal’s health.</em> The impacts of global warming are due to the process of denitrification through loss of nitrous oxide.
