A point mutation is a mutation that affects only a single nucleotide of a nucleic acid. They involve substitution of one base for another which changes the complementary base as well in DNA, they may also involve insertions and deletions of a single base pair. I therefore think the point mutations in a DNA sequence may profoundly have an effect on the synthesis of proteins, or may also have no effect on protein synthesis at all. These mutations can be beneficial to an organism, however they are more commonly neutral or harmful.
Based on the structure and arrangements of nucleotides in the <u>DNA </u>molecule, the molecule is an information molecule. It stores instructions and is read to produce proteins that direct cellular reproduction, produce new cellular components, and initiate cellular reproduction.
<h3>Describe DNA.</h3>
Deoxyribonucleic acid is referred to as a DNA Trusted Source. It includes units known as nucleotides, which are biological building blocks.
For most other organisms in addition to humans, DNA is an essential chemical. Our genes and genetic material, which are what gives us our individuality, are both found in our DNA.
<h3>What is the DNA's structure?</h3>
A DNA molecule is created from a group of nucleotides. There are three components in each nucleotide:
- a phosphate group
- a sugar
- a base of nitrogen
The name of the sugar in DNA is 2-deoxyribose. The "backbone" of the DNA strand is made up of these sugar molecules that are in alternation with phosphate groups.
In a nucleotide, each sugar is joined to a nitrogen base. Nitrogen bases come in four main varieties in DNA. They consist of:
- adenine (A)
- cytosine (C)
- Thymine(T)
- guanine (G)

Answer:
ensures high level of competition
In order for plants to assimilate nitrogen directly into their system, the nitrogen must be in the form of nitrates. Nitrogen in the air and ammonia from decayed matter in the soil is converted to ammonium by decomposers and nitrogen-fixing bacteria. The ammonium is further nitrified to nitrates by nitrifying bacteria. Finally, the nitrates can then absorbed by the plants.
<u>Answer</u>:
Once a human is infected with a virus, bacterium, fungus, or parasite they interfere with the human’s normal body function
.
<u>Explanation</u>:
The infection due to the pathogen are not always end up as a disease. Infection occurs when any pathogen comes inside the human body it can be virus, bacteria or can be fungus, and starts multiplying by getting suitable environment as well as the host. The microbes sometimes challenges the immune system and lowers the resistance power the body. So, as viruses does by killing the fighter cells and also by disrupting the general cell functions.
