What is Optical Microscopy?

Optical microscopy is a technique employed to closely view a sample through the magnification of a lens with visible light. This is the traditional form of microscopy, which was first invented before the 18th century and is still in use today.

Optical Microscopy Techniques

The techniques used in optical microscopy are important to ensure that a sample can be viewed as clearly as possible. This will provide information about its microscopic appearance.

Limitations of Optical Microscopy

Optical microscopy is a very useful technique to examine the appearance of a sample with greater detail, but there are some limitations that provide a boundary to its use in practice.

Emerging Trends in Proteomics

Proteomics is a branch of molecular biology that focuses on the protein expression within an organism or cell. It is a comprehensive study with high throughput of a specific proteome to identify particular cellular processes.

Macromolecules: Polysaccharides, Proteins and Nucleic Acids

Water, organic molecules, and inorganic ions are the constituents of cells. Water constitutes the greatest fraction of the three, accounting for almost three-quarters of the total mass of a cell. The interactions between the various components of a cell and its water content is key to biological chemistry.

Gut Microbiota

The human body is colonized with a dense community of more than 100 trillion microbes, most of which live in the gut. The “good” microbes in the gut aid the digestion of food, regulate the immune system, make certain vitamins and protect against harmful bacteria.

Skin Microbiota

The skin microbiota is the term used to describe the collection of microorganisms that live on our skin. More specifically, it refers to the genomes of all these microbes including bacteria, fungi, protozoa, viruses, and mites living.

Oral Microbiota

The mouth is colonized by a rich and diverse microbial community made up of more than 700 different species of bacteria, certain species of fungi, and even protozoa.

Microbiome and Disease

The microbiome is the collective term used to refer to all of the microbes found in or on the human body and more specifically, the genomes of those microbes.

Human Microbiome

The human microbiome refers to the spectrum of microbes (microbiota) that colonize humans. More specifically, it refers to the microbial genomes of all the bacteria, fungi, protozoa, and viruses that are found inside or on the body.

Human Microbiome Project (HMP)

The human body is colonized by thousands of microbial species, together referred to as the microbiome. Humans have about ten times more microbial cells than human cells, and the number of genes contained in the microbiome is more than 100 times greater than the number found in the human genome.

Achievements of the Human Microbiome Project

The human microbiome refers to the entire community of microorganisms that live on or in the human body. More specifically, it refers to all of the genes in these microbes, which include bacteria, fungi, protozoa, and viruses.

What is Metagenomics?

Metagenomics is the study of microbes in their natural living environment, which involves the complex microbial communities in which they usually exist. The study examines the genomic composition of an entire organism, including each of the microbes that exist within it.

Structure of DNA

The discovery of DNA structure by James Watson and Francis Crick in the year 1953 is one of the most revolutionary scientific discoveries to date. However, the research leading to the discovery of nucleic acid structure started several years previously and involved many different researchers across the world.

What is the RNA World Hypothesis?

The RNA World Hypothesis is a concept put forth in the 1960s by Carl Woese, Francis Crick and Leslie Orgel. It proposes that earlier life forms may have used RNA alone for the storage of genetic material.

Prokaryotes

Prokaryotes were the first kind of organisms to evolve. They are single-celled organisms that don’t have a well-defined nucleus and also lack other membrane-bound organelles such as mitochondria. The genetic material in prokaryotic cells exists within an irregularly shaped area of the cell known as the nucleoid.

What is Structural Genomics?

Structural genomics is a field of genomics that involves the characterization of genome structures. This knowledge can be useful in the practice of manipulating the genes and DNA segments of a species.

Applications of Genomics

The knowledge and understanding acquired from genomics research can be applied in a number of different settings, including medicine, biotechnology and social sciences. Although the applications of genomics have already found a place in many areas, there is potential for the study to revolutionize fields involving human and other life on earth even further in the future.

History of Metabolomics

Metabolomics is a relatively new field of research and the youngest of the triad of systems biology that it is part of, alongside genomics and proteomics. The term “metabolome” was first introduced in 1998, and even up to 2010 metabolomics was regarded as an emerging field.
