What is DNA made of?
The genetic information carried on the DNA segments is called genes. DNA is made up of two polymers that are formed by smaller units called nucleotides . The polymers have backbones made of phosphate and sugar combined by ester bonds. The polymers are not parallel as they run in opposite directions.
What is the compound that makes up all living things?
All living organisms contain a complex organic compound called nucleic acid. Johann Friedrich Miescher (1844-1895), a Swiss biochemist, discovered nucleic acid s in 1869. He found out that the cell nuclei contained a rather unusual compound and he named it nuclein. The unusual nature of the compound was brought about by the presence of phosphorus and nitrogen, as well as oxygen, hydrogen and carbon. This made nuclein among the first organic compounds discovered to contain that combination of elements. However, further research showed that different types of nuclein were present in different parts of a cell. For this reason, the name was modified to its present name - nucleic acid .

What is the structure of nucleic acids?
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.
How does mRNA bond to tRNA?
Once bonded, the mRNA strand is pulled through the ribosome, exposing a new codon that another tRNA molecule bonds to. The two amino acids are then joined together by a peptide bond. this process continues until the ribosome reads a “ stop codon ,” special codons that signify the end of a polypeptide strand.
Why is DNA in specific proportions?
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.
What is the role of nucleic acids in gene expression?
Each kind of nucleic acid performs a particular role in gene expression. Molecules of DNA encode information for constructing proteins; they are like the building blueprint in our construction analogy. 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 is a Nucleic Acid?
Nucleic acids hold the information that make a lion a lion, a tree a tree, and a person a person. They are the molecules that contain all the information necessary for an organism to develop traits, carry out life functions, and reproduce. It could be argued that nucleic acids are the most important molecule within any living thing.
Nucleic Acid Description
The three parts of nucleic acids are the phosphate groups, 5-carbon sugars, and nucleotides. However, it is the repeating chain of these three molecules that make up the nucleic acid as a whole. Let's look at each part of a nucleic acid more closely.
Types of Nucleic Acid
As mentioned before, there are two main types of nucleic acids. They are deoxyribose nucleic acid (DNA) and ribose nucleic acid (RNA). DNA can be found in both eukaryotes (cells that contain a nucleus) and prokaryotes (cells that do not contain a nucleus). All multicellular organisms are made up of eukaryotic cells.
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:

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 …
