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 are the components of nucleic acids?
There are five chief types of components in nucleic acids: cytosine, guanine, thymine, uracil, and adenine. Whether the acid contains uracil or thymine determines whether it is DNA (thymine) or RNA (uracil).

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 .

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.
What are the two types of nucleic acids?
There are two types of nucleic acid: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Both play a central role in every function of every living organism. Nucleic acids have similar basic structures with important differences. They are composed of monomer nucleotides connected like links in a chain to form nucleic acid polymers. Nucleotides consist of a nucleoside (the combination of a pentose monosaccharide molecule and a nitrogenous base) and a phosphate group. The difference between RNA and DNA lies in a single nitrogenous base and a single atom of oxygen within a sugar molecule.
What is the primary structure of nucleic acids?
The primary structure of the nucleic acid refers to the sequence of its nucleotide bases, and the way these are covalently bonded to each other. The sequence of “letters” in a strand of DNA or RNA, then, is part of its primary structure, as is the helical or double-helical shape.
What are the two strands of DNA?
These are naturally occurring compounds which give each nucleotide its name, and are divided into two groups – pyrimidines and purines. While the pyrimidines cytosine, thymine and uracil (see RNA) are small, single-ringed constructions, adenine, and guanine are larger and double-ringed. This difference in shape and size and a subsequent difference in electrical charge is important, as it allows only specific complementary pairings between different group types; in DNA, adenine will only bond with thymine and cytosine will only bond with guanine. This creates nitrogenous base spindles of the same length and a mirror image on the opposite strand.
What does nucleic acid structure mean?
“Nucleic acid structure” can mean something as simple as the sequence of nucleotides in a piece of DNA. Or, it could mean something as complex as the way that DNA molecule folds and how it interacts with other molecules.
What are the two components of a nucleotide?
Nucleotides – the building blocks of nucleic acids, and the “letters” of the genetic “code” – are made of two components: A nitrogenous base such as adenine, cytosine, guanine, and thymine or uracil.
What is the structure that occurs when a single RNA molecule folds back and hydrogen bonds with itself?
Other structures are also possible, such as a “stem-loop” – which occurs when a single RNA molecule folds back and hydrogen bonds with itself – or a four-armed structure that can occur when four different strands of nucleic acid hydrogen bond with different parts of each other.
Why is RNA important for the production of proteins?
RNA is found in every type of cell. It is essential for the production of proteins via the replication of genetic information. Using the DNA blueprint, RNA in various forms copies and transfers encoded genetic data to cellular ribosomes. In turn, the ribosomes translate this data into the form of proteins. RNA is not associated with the double-helix structure of DNA. However, it has the ability to form this structure for a temporary period and exists in single strands of varying lengths. Even in denucleated red blood cells, RNA continues to carry out the process of transcription. This is because protein biosynthesis is necessary for every reaction within a living organism.
