A DNA, or deoxyribonucleic acid, is the hereditary genetic material for most living organisms. DNA is present in cells in the form of a double-stranded helix that is composed of long strands of nucleotides. The unique sequence of nucleotides within the DNA molecule stores the genetic information. process by which an organism is genetically changed, resulting in a mutation, which is a change in the DNA sequence of a gene. It may occur naturally, for example, due to natural exposure to ultraviolet (UV) light or chemicals; or it can happen deliberately for the purpose of increasing genetic variation of a species.

- The Avery-MacLeod-McCarty experiment, a continuation of the Griffith experiment, proved DNA, not proteins, are responsible for trait retention in offspring. Later Hershey and Chase took a radical approach with radio-tagging phosphorous and sulfur molecules in viruses to determine which of the two were passed on to offspring. Their experiment confirmed the conclusion of the Griffith and Avery-MacLeod-McCarty experiment, DNA contains hereditary information.

Heredity Heredity is the passing on of traits from parents to their offspring, either through asexual reproduction or sexual reproduction; the offspring cells or organisms acquire the genetic information of their parents. Through heredity, variations between individuals can accumulate and cause species to evolve by natural selection. The study of heredity in biology is called genetics, which includes the field of epigenetics.

MADMAN BIOLOGY A set of human chromosomes contains one copy of each of the roughly 30,000 genes in the human genome - the term used to refer to the complete genetic instructions for an organism. DNA is found throughout the body. Each cell contains all of the organism's genetic instructions stored as DNA. However, each cell uses only the instructions from part of the DNA. For example, a muscle cell uses the DNA that specifies the muscle apparatus, whereas a nerve cell uses DNA that specifies the nervous system.

Latest News A gene is a basic unit of heredity in a living organism that normally resides in long strands of DNA called chromosomes. Genes are coded instructions that decide what the organism is like, how it behaves in its environment and how it survives.

- An organism may have thousands of genes. The set of all genes in an organism is called a genome. A genome can be compared to a cookbook of recipes that makes that organism what it is. Every cell of every living organism has a cookbook.his characteristic is critical to the success of genetic engineering. When a gene for a desirable trait is taken from one organism and inserted into another, it gives the recipient organism the ability to express that same trait.

DNA It is the repository for the hereditary information. DNA accomplishes protein production by first providing a pattern for the production of mRNA, a process called transcription. The RNA then contains the information from the DNA to manufacture a protein, a process called translation.Some proteins are structural, but some are control proteins called enzymes. These enzymes are employed in the production of proteins, even copies of themselves, so enzymes are used to make other enzymes.t is the repository for the hereditary information.

Heredity In humans, eye color is an example of an inherited characteristic: an individual might inherit the brown-eye trait from one of the parents. Inherited traits are controlled by genes and the complete set of genes within an organism's genome is called its genotype.The complete set of observable traits of the structure and behavior of an organism is called its phenotype. These traits arise from the interaction of its genotype with the environment.As a result, many aspects of an organism's phenotype are not inherited.he complete set of observable traits of the structure and behavior of an organism is called its phenotype.

II.1 Genetic information is carried by nucleic acid in contemporary organisms. Genetic information is encoded in DNA in aperiodic sequences of four kinds of nucleotides, i.e. deoxyadenosin-5´-phosphate (A), deoxythimidin-5´-phosphate (T), deoxyguanosin-5´-phosphate (G) and deoxycitidin-5´-phosphate (C), in long, unbranched chains of the double-helix nucleic acid.enetic information is encoded in DNA in aperiodic sequences of four kinds of nucleotides, i.e. deoxyadenosin-5´-phosphate (A), deoxythimidin-5´-phosphate (T), deoxyguanosin-5´-phosphate (G) and deoxycitidin-5´-phosphate (C), in long, unbranched chains of the double-helix nucleic acid.

- Biological inheritance is broadly defined as physical heredity. Heredity, or inheritance in the biological sense, refers to the physical features that offspring inherit from their parents, such as eye color, shape of nose and mouth, height and other distinguishing physical characteristics.

About Truffles The black truffle or Tuber Melanosporum, also known as the Perigord truffle, grows mainly in France and Italy and is the variety most commonly cultivated in a truffle orchard or trufferie. With a unique scent, they our sniffed out by trained pigs and dogs.he ripe truffle, when cut, exhibits a dense black interior that is streaked with white veins. The truffle is firm and resembles the texture of a potato. The outside has a fairly tough, scaly skin that can withstand the conditions in which the truffle grows.

DNA Because DNA collects mutations over time, which are then inherited, it contains historical information, and, by comparing DNA sequences, geneticists can infer the evolutionary history of organisms, their phylogeny. This field of phylogenetics is a powerful tool in evolutionary biology.he two DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides. Each nucleotide is composed of a nitrogen-containing nucleobase —either cytosine (C), guanine (G), adenine (A), or thymine (T)—as well as a monosaccharide sugar called deoxyribose and a phosphate group.

Heredity Heredity is the genetic information passing for traits from parents to their offspring, either through asexual reproduction or sexual reproduction. This is the process by which an offspring cell or organism acquires or becomes predisposed to the characteristics of its parent cell or organism.

For example, suntanned skin comes from the interaction between a person's phenotype and sunlight; thus, suntans are not passed on to people's children.
