What are Nucleic acids?Nucleic acids are biopolymers, which are essential to all known forms of life. They are composed of nucleotide polymers. Nucleotides are the monomers of nucleic acids which are made up of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Nucleic acids play essential roles in all cells and viruses. The main function of nucleic acids involves storage and expression of genetic information in organisms. Deoxyribonucleic acid (DNA), encodes the information cells need to make proteins.
Therefore, the correct option is A.

Why do we rely on lactic acid fermentation only as a temporary energy source?
Answers
Answer:
This usually happens when there is not enough oxygen in the body, so lactic acid fermentation provides a way to get ATP without it. The process relies on stored energy sources such as sugars or starches, which it can break down to make simpler molecules and energy. ... Lactic acidosis usually occurs because of exercise.
The process relies on stored energy sources such as sugars or starches, which it can break down to make simpler molecules and energy. Lactic acidosis usually occurs because of exercise.
What is lactic acidosis?Lactic acidosis refers to lactic acid build up in the bloodstream. Lactic acid is produced when oxygen levels become low in cells within the areas of the body where metabolism takes place.
The symptoms of lactic acidosis include abdominal or stomach discomfort, decreased appetite, diarrhea, fast, shallow breathing, a general feeling of discomfort, muscle pain or cramping.
Lactic acidosis occurs when lactic acid production exceeds lactic acid clearance. The increase in lactate production is usually caused by impaired tissue oxygenation, either from decreased oxygen delivery or a defect in mitochondrial oxygen utilization.

A bacterium, containing one circular DNA chromosome, undergoes four rounds of replication. How many new strands of DNA would result?
Answers
Answer:
The correct answer is 32 strands.
Explanation:
In bacterium, DNA replication is bidirectional which means it takes place in both directions. The origin of replication starts the replication, it is a specific sequence of nucleotides. Each strand of circular DNA acts as a parent strand to replicate its complementary new strand, resulting in two new DNA strands, one parent strand, and one new synthesized strand. So after the first round of replication, there are 4 strands formed.
Similarly, during the second round of replication each of the four strands will be synthesized lead to a total of 8 strands in the same manner. So by the same process in 3rd round will lead to 16 new strands and by the fourth round of replication 32 strands will be synthesized.
Thus, the correct answer is 32 strands.
