The two nucleic acids differ in their structure, function, properties, and location within the cell. We will discuss these nucleic acids in detail in this section. DNA. DNA also known as deoxyribonucleic acid is the most important biological molecule present in living cells. All the genetic information is stored in the cell in the form of DNA.

In an essay on role of nucleic acids for example, talking about the job of the proteins they code for is off-topic and will LOSE you marks. Also common errors like saying DNA is made from polypeptide strands or that DNA is a protein will lose you these marks. STICK TO THE POINT. QUALITY I should not have to say much here, but quality goes beyond physical sentence construction. Think about the.

Sample Essay on Nucleic acid sequence - Essay Homework.

Nucleic acids are linear polymers of nucleoside monophosphates, that is, polynucleotides. Nucleotides are constructed from three components: pyrimidine or purine base, carbohydrate (pentose) and phosphoric acid. Nucleotides are linked together in a chain by a phosphodiester bond. It is formed due to the esterification of the OH group of the C-3-pentose of one nucleotide and the OH group of the.The Lesson Summary. The knowledge that 24-year-old Miescher derived from studying the pus on dirty hospital bandages led to the discovery and analysis of nucleic acid.Nucleic acid has two types, DNA and RNA, which not only helps us understand how life is determined, controlled and passed on, but also opened the door to a new technologies.All biological functions depend on events that occur at the molecular level. These events are directed, modulated, or detected by complex biological machines, which are themselves large molecules or clusters of molecules. Included are proteins, nucleic acids, carbohydrates, lipids, and complexes of them. Many areas of biological science focus on the signals detected by these machines or the.


Biophysical Properties Of Bio Macromolecules Essay. biopolymers such as nucleic acids, proteins and carbohydrates are essential for life as we see it today. It is incredible to think how this vast set of molecules that are in every living thing, from bacteria to human beings, are mostly made up by six elements (carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus). These biopolymers have.Functions of nucleic acids essay writer. 12.11.2018.

The sugar phosphate backbone of a nucleic acid is directional, as in the peptide-bonded backbone of a polypeptide. v. In a strand of RNA or DNA, one end has an unlinked 5’ carbon while the other has an unlinked 3’ carbon—meaning a carbon that is not linked to another nucleotide. 5’ 3’ direction. vi. The sequence of nitrogenous bases forms the primary structure of a molecule.

Nitrogen is essential for all living things because it is a major part of amino acids, which are the building blocks of proteins and of nucleic acids such as DNA, which transfers genetic information to subsequent generations of organisms. About 78 percent of the atmosphere is made of nitrogen, but plants and animals can't take nitrogen directly from the air. A process called the nitrogen cycle.

The Polymerase Chain Reaction is essentially a cell-free method of DNA and RNA cloning. The DNA or RNA is isolated from the cell and replicated upto a million times. At the end, what you get is a greatly amplified fragment of DNA. The PCR is quick, reliable and sensitive and its variations have made it the basis of genetic testing.

In biology, function has been defined in many ways. In physiology, it is simply what an organ, tissue, cell or molecule does.In evolutionary biology, it is the reason some object or process occurred in a system that evolved through natural selection.That reason is typically that it achieves some result, such as that chlorophyll helps to capture the energy of sunlight in photosynthesis.

The Functions of Proteins in Plants and Animals Proteins are polymers of monomers called amino acids. Amino acids contain hydrogen, carbon, oxygen and nitrogen. When amino acids are linked together, they form polypeptide chains and bonded together by peptide bonds. There are different structures of polypeptides primary, secondary, tertiary and quaternary. The primary structure is a straight.

These structures will be the key to the macromolecules functions as each of them do a specific task in the torso. Macromolecules are grouped into carbohydrates, nucleic acids, protein, and lipids. In most cases macromolecules are polymers, which really is a long molecule which are created by linking alongside one another a large volume of small, similar substances called monomers.
