Structure Of Nucleic Acids. All nucleic acids share a common core chemical structure. All nucleic acids are linear polymers of nucleotides. Each individual nucleotide is composed of a nitrogenous base, a 5-carbon sugar, and a phosphate group. The chemical identity of each nucleotide is determined by its nitrogenous base.
What are the four types of nucleotides?
Molecules of DNA contain 4 kinds of nucleotides, adenine (A) cytosine (C), guanine (G) and thymine (T). Adenine and guanine are classified as purines while cytosine and thymine are classified as pyrimidines. Nucleotides join together via complementary base pair conjugation. Each nucleotide has a complementary pair that it forms bonds with. Cytosine and guanine are complementary base pairs (C-G) and adenine and thymine (A-T) are complementary. The double strands of DNA link in the middle by each nucleotide bonding with its complementary base. The particular geometric structure of DNA explains why its nucleotide bases are always in specific proportions to each other; specifically, the amount of adenine is roughly equal to the amount of thymine and the amount of cytosine is about equal to guanine.

RNA molecules function to extract this information out of DNA and physically assemble the proteins.
How does RNA polymerase work?
One the two strands are split, RNA-polymerase binds to the template strand and begins to “walk” along the strand from the 5′ to the 3′ end. As it goes along, the RNA-polymerase “builds” the mRNA by adding complementary base pairs.
Which pair of nucleotides forms a bond?
Each nucleotide has a complementary pair that it forms bonds with. Cytosine and guanine are complementary base pairs (C-G) and adenine and thymine (A-T) are complementary. The double strands of DNA link in the middle by each nucleotide bonding with its complementary base.
What are the parts of a nucleic acid?
A nucleic acid is a chain of repeating molecules made up of three parts. These three parts are: a phosphate group, a 5-carbon sugar, and a nucleotide. This pattern repeats over and over again. The only difference between the repeating chains in nucleic acids is in the nucleotides. It is the number and order of the nucleotides in each nucleic acid molecule that determines an organism's traits. Without nucleic acids there would be no way to store genetic information, and life would never have evolved on planet Earth.
How do you think of nucleic acids?
A helpful way to think of nucleic acids is that they have a similar shape to a ladder. DNA is normally coiled around itself, but, if it were stretched out, it would look like a ladder with the phosphates being the sides of the ladder, the 5-carbon sugar being where the rungs (the middle part of a ladder) connect to the sides of the ladder, and the nucleotides would be the rungs themselves. RNA has the same structure as DNA except that it is only half or one side of the ladder.
What are the nucleotides in DNA?
The nucleotides that make up DNA are adenine, cytosine, guanine, and thymine. In RNA, however, the thymine nucleotide is replaced by a uracil nucleotide. This mean RNA is made up of aden ine, cytosine, guanine, and uracil. It is the order of these nucleotides in both DNA and RNA that determine an organism's traits and the proteins that it can make.
How are DNA and RNA similar?
DNA and RNA have similar structures, but there are two main differences between these nucleic acids. The first difference is that DNA is made up of two strands of nucleic acids, while RNA is only made up of one strand. The second difference is that DNA uses the nucleotide thymine in its structure, while RNA uses the nucleotide uracil. For a clearer example of these differences look at the diagrams below.
What is the name of the sugar in DNA?
In DNA the 5-carbon sugar is deoxyribose , and in RNA it is ribose. This is where the two molecules get their names from. DNA stands for deoxyribose nucleic acid, while RNA stands for ribose nucleic acid. The 5-carbon sugar connects the phosphate group and the nucleotide in a nucleic acid molecule.
What is the phosphate group of a nucleic acid?
It is the phosphate group that makes up the backbone, or the sides of the nucleic acid. If we go back to our ladder analogy, the phosphate group would represent the sturdy sides of the ladder.
What is the function of DNA and RNA?
They are both ways to store genetic information, but only RNA can be used by the cell to make the proteins necessary for life functions. DNA is the nucleic acid that contains the information for all of the traits of an organism. It is this molecule that is replicated during cell division. This is when a cell creates an identical copy of itself, and the new cell has all of the genetic information that it needs to survive and carry out its functions.

Answer: Amino acids can be broadly classified into three classes i.e. acidic, alkaline and neutral amino acid s depending on the number of —NH2 group and — COOH group.
Nucleic acids benefits
Despite limited research, proponents claim that foods rich in nucleic acids can offer a variety of benefits — from a stronger immune system to improved digestion and quicker muscle recovery ( 2 ).
1. Meat
At 1.5–8 grams of nucleic acids per 3.5 ounces (100 grams), meat is considered one of the foods richest in these compounds ( 2, 3 ).
2. Fish
Fish is another rich source of nucleic acids. Like meat, fish is thought to provide 1.5–8 grams of nucleic acid per 3.5 ounces (100 grams) ( 3 ).
3. Seafood
Seafood can be split into two categories. Both categories provide a significant, albeit smaller, source of nucleic acids than meat and fish. These include:
4–6. Beans, peas, and lentils
Beans, lentils, and peas are other interesting sources of nucleic acids. Vegans and vegetarians can still get the benefits of nucleic acids in their diets with legumes.
7. Mushrooms
Most vegetables contain very few nucleic acids. Mushrooms may be the sole exception.
The bottom line
Nucleic acids are found in all living things, including the foods you eat.
Clinical significance
- Some DNA mutations in mitochondria have been linked to diseases of the heart and muscles. When there is damage to the mitochondrial DNA, tissues and organs can begin to deteriorate causing painful and sometimes fatal conditions. Mutations of the genes BRCA1 and BRCA2 have been linked to causing breast cancer. This determination, in the 1990's, has ...
Prevention
- The same genes that were determined to cause breast cancer upon mutation have also been linked to ovarian cancer. Researchers are still working to determine how these mutations happen and how to prevent them.
Cause
- Alzheimer's Disease is another disease caused by mutation of genes in one's DNA. Presenilin-1, Presenilin-2, and APP are three genes that are known to contribute to the onset of Alzheimer's. Further, the hereditary nature of Alzheimer's had lead researchers to study the genes that must be inherited in order to develop the disease. If a mutated gene is inherited, the likelihood of acquirin…
Overview
- Cystic Fibrosis is an inherited disease that affects the secretory glands that are responsible for producing mucus and sweat. Cystic Fibrosis can affect the pancreas, the lungs, intestines, sinuses and even sex organs. With research, the prognosis for those with Cystic Fibrosis is improving, but a much decreased life expectancy is very common.
Genetics
- While certainly not as debilitating as some other genetic diseases, color blindness is also a result of mutation of genes on DNA. This condition is more prevalent in men and exists when one is unable to distinguish between colors or to see colors in typical lighting.
Prognosis
- This genetic disease affects children most often. Infantile Tay-Sachs Disease generally commences around 6 months old, culminating in fatality by the age of four while juvenile Tay-Sachs disease starts between the ages of 2 and 10 with death occurring most often by age 15. Rarely, adult onset Tay-Sachs will begin in one's 30's or 40's; but, many times it is not fatal. After …
