DNA's Functional 'Biological' Purpose: DNA has two main biological functions (aside from being a very elegant looking macromolecule). Primarily, it serves to store/determine the biological characteristics of any living thing according to a very specific arrangement of molecular connections, as will be defined in a later section of this site.

How DNA Works What DNA Does. ­DNA carr­ies all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein.In DNA, each protein is encoded by a gene (a specific sequence of DNA nucleotides that specify how a single protein is to be made).Specifically, the order of nucleotides within a gene specifies the order and types of amino acids that must be put together to make a protein.n DNA, each protein is encoded by a gene (a specific sequence of DNA nucleotides that specify how a single protein is to be made).

- DNA fills this role by containing three-base sections -- called codons -- that direct the formation of proteins. In a long stretch of DNA, each codon contains the information that directs the assembly of one amino acid onto a protein.efore their discovery, the scientific community retained some skepticism that DNA was up to the job, because it seemed too simple a molecule to perform the four necessary functions: replication, encoding, cell management and the ability to mutate. The unique structure of DNA allows it to fulfill all these functions.

What are the three functions of DNA in the Cell? To divide itself and create new DNA strands which can be used in new cells when the original cell undergoes mitosis. To form RNA strands. when DNA divides the exposed strand attracts complementary bases from the nucleus which are the RNA base pairs.

What Are the Two Major Functions of Nucleic Acid in Living Things? The main job of DNA is to carry the code for making proteins. A gene is a stretch of DNA that can be read by proteins called ribosomes, and copied into a type of nucleic acid called messenger RNA (mRNA). The mRNA then carries this information to a protein machine that reads the information in mRNA and makes proteins.

Nucleic acids contain genetic information and enable synthesis of proteins. Nucleotides are used to make Nucleic Acids. Nitrogenous bases in DNA are Adenine, Cytosine, Guanine, and Thymine. All DNA is double-stranded. The two strands are antiparallel (pointing in opposite directions). The backbone of each strand is the chain of sugars and phosphates. The nitrogenous bases of each strand are in the center, pointing toward the other strand. Each nitrogenous base forms hydrogen bonds with the complementary base pair on the opposite strand.

- DNA is organized in sections called genes. Genes code for proteins, and it is proteins that do all the work in the cell. They function as structural proteins — serving as the building blocks of cells and bodies. And they function as enzymes — directing all the chemical reactions in living organisms.

helicase The process of breaking the hydrogen bonds between the nucleotide base pairs in double-stranded DNA requires energy. To break the bonds, helicases use the energy stored in a molecule called ATP, which serves as the energy currency of cells. DNA helicases also function in other cellular processes where double-stranded DNA must be separated, including DNA repair and transcription.

What do the letters DNA stand for.? Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules.

An Introduction to Molecular Biology/DNA the unit of life Deoxyribonucleic acid (DNA) is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. Along with RNA and proteins, DNA is one of the three major macromolecules essential for all known forms of life.he four bases found in DNA are adenine (abbreviated A), cytosine (C), guanine (G) and thymine (T). These four bases are attached to the sugar/phosphate to form the complete nucleotide, as shown for adenosine monophosphate.

What does DNA DO? DNA is found in each cell (in the nucleolus), as it carries all of our genetic information necessary for protein synthesis, the next replication cycle and of course for “meiosis” - so therefore DNA replication is important in order to carry on the existence of a living organism.

What Is the Composition of a Chromosome? One of the main functions of chromatin is to reduce the size of DNA so it can fit in the cell. It does this by wrapping a DNA molecule tightly around proteins called histones. The histones are there to maintain the structure of the chromosome. Other functions of chromatin include reinforcing DNA molecules for mitosis, preventing DNA damage, and helping to control DNA replication.

- What is the function of the genetic material in a cell? The two main functions of the genetic material in a cell, also known as DNA, are gene expression and replication. DNA accomplishes gene expression by providing the instructions necessary for cell machinery to make proteins. Replication occurs when the DNA makes a copy of itself for incorporation into a new cell.

- The primary function of the genome is to store, propagate, and express the genetic information that gives rise to a cell’s architectural and functional machinery. However, the genome is also a major structural component of the cell. Besides its genetic roles, the genome affects cellular functions by nongenetic means through its physical and structural properties, particularly by exerting mechanical forces and by serving as a scaffold for binding of cellular components.

The Structure and Function of DNA as the Molecule of Inheritance DNA is a big and long polymer made of subunits called nucleotide monomers. Each nucleotide monomer is made of a nitrogenous base, a 5-carbon sugar (ribose or deoxyribose), and a phosphate group. In DNA, there are four nucleotide bases: cytosine (C), adenine (A), guanine (G), and thymine (T).ritten by: Rafael•edited by: Paul Arnold •updated: 2/8/2010. The structure and function of DNA are highly interrelated. From the composition of base pairs to their spacial arrangement understanding the structure and function of DNA as the molecule of inheritance is of paramount importance to grasp modern genetics.
