DNA

DNA (Deoxyribonucleic acid), of the shape of a double helix, found in the nucleus of a cell, is where genetic information is encoded and transferred. It has all the instructions needed for the development and functioning of an organism. DNA segments are known as genes. DNA research is a very complex scientific study which aids in finding complicated evolutionary information in humans and animals. It is a vast topic that has aided theories and discoveries in many diverse areas. The articles given below present DNA research in clearer light. They also tell you about the structure and composition of DNA, and also about DNA sequencing and replication.
  • How Does DNA Replicate
    Have you ever wondered how does DNA replicate? This article will tell you all you need to know about DNA replication and the steps involved in this process.
  • What Makes up DNA?
    DNA or deoxyribonucleic acid is known as the building block of life. Mainly composed of protein, the DNA has a key role in life and is considered to be the storehouse for genetic traits.
  • Nucleotides in DNA
    DNA is a polynucleotide. The genetic information, consisting of thousands of codes is carried by the nucleotides in DNA. This genetic information helps a person to know about his ancestors. Let's discuss more about this most essential part of our life.
  • What is a Nucleotide
    We may never have been able to find out about our ancestors if what is a nucleotide remained a question. It is known as the box of information which is carried through generations. So, let's go through some of its essential information and explore the world of nucleotide.
  • Why is DNA Important
    The information about why is DNA important to living things is presented through the following article. DNA tests play an important role in research and also to carry out different tasks pertaining to fields such as forensic science, genealogy, etc.
  • DNA Replication Enzymes
    DNA replication, the basis of biological inheritance, is made possible by certain enzymes present in cells. In this article, I talk about the prime replication enzymes and their functions.
  • Nucleotide Structure
    The nucleotide structure has eluded many scientists for years. However, recent breakthrough in the field of genetics has helped us understand more about nucleotide structure. Read on to find out about the structure of nucleotide and what all molecules and compounds comprise a nucleotide...
  • Chromatin Function
    If you are looking for information about chromatin function and structure, you've landed on the right page. This article explains the eukaryotic chromatin function and the important role it plays in cell division and inheritance.
  • DNA Replication Process
    The DNA replication process is a procedure wherein the DNA double helix splits and duplicates itself to make copies of the strands of DNA. Read on to know more about DNA replication, and the process involved...
  • Purines and Pyrimidines
    The following article answers that questions what are purines and pyrimidines, their chemical properties, the purines and pyrimidines structure and the functions in short.
  • DNA Replication Steps
    DNA replication is a process, by which another copy of a double stranded DNA is produced. There are many complex steps involved for completion of this process. Let us have a short insight into the interesting and intriguing process of DNA replication steps.
  • Difference between DNA and RNA
    Technically, ribonucleic acid and deoxyribonucleic acid sure sound alike. But let's face it, in the human body, redundancy does not exist. Check out this article to understand the difference between DNA and RNA.
  • Mitochondrial DNA and Human Evolution
    The evolution of man has always been a matter of great interest and a widely debated topic in recent times. DNA is present in each cell of the human body. The DNA of mitochondria in the cell, can be used to reconstruct the evolutionary history of the human species.
  • DNA Extraction
    A process that extracts DNA from a cell, by segregating it from cellular constituents such as lipids and metabolites, is called DNA extraction.
  • DNA Sequencing
    DNA sequencing is a revolutionary concept in biological research that attempts to decode the human body and its working. The accurate mapping of genes and genomes is achieved through this sequencing technology. Read on to learn more...
  • DNA Translation
    In a nutshell, DNA translation can be defined as the process that "translates" information contained in the nucleic acids (DNA and RNA) to facilitate polypeptide or protein synthesis.
  • DNA Replication
    Replication of DNA is an important process that involves a number of proteins and enzymes. This ensures that the amount of genetic material is not reduced from parent to the offspring. Read on to know more about the steps in DNA replication.
  • Mitochondrial DNA Testing
    Mitochondrial DNA testing is one test that helps us to trace and unravel our maternal ancestry. To know more about mitochondrial DNA testing, read on...
  • Structure of Mitochondrial DNA
    Mitochondrial DNA is the genetic material that is found in mitochondria, the organelles which provide energy to cells and are hence called their powerhouses.
  • Functions of Mitochondrial DNA
    Mitochondrial DNA or mtDNA is the deoxyribonucleic acid present in the mitochondria organelles. This DNA was discovered by Margit and Sylvan Nass via electron microscopy. The discovery enabled an understanding about the role it plays to convert food energy into usable cell energy.
  • How is Mitochondrial DNA Used in Forensics
    Mitochondrial DNA analysis is a boon in forensic studies, as it is used to solve difficult cases, especially in case of degraded samples that lack nuclear DNA. Here is some information on how mitochondrial DNA is used in forensics.
  • Who Discovered DNA
    Our DNAs are a unique bond of molecules that determine our very beings and also differentiate each of us from another. So who discovered DNA in the first place that paved a great way into the science of the human body?
  • Biochips Part 2
    Breaker's invention opens the way for future RNA chips capable of revealing the molecular composition of complex mixtures-like blood serum and industrial waste-far more comprehensively than current biochips.
  • Biochips
    The S4MS chip is for sensing oxygen or glucose. Light generated by the light-emitting diode (LED) causes surrounding molecules to fluoresce. The light that emerges has a new wavelength, and only this light passes through the filter to be detected by the photodiode. The oxygen or glucose decreases the fluorescence of the molecules in the top reservoir.
