- Recombinant DNA is the general name for a piece of DNA that has been created by the combination of at least two strands.Recombinant DNA molecules are sometimes called chimeric DNA, because they can be made of material from two different species, like the mythical chimera.-DNA technology uses palindromic sequences and leads to the production of sticky and blunt ends. The DNA sequences used in the construction of recombinant DNA molecules can originate from any species. For example, plant DNA may be joined to bacterial DNA, or human DNA may be joined with fungal DNA.

- Species hypothesized to have the same ancestors are placed in one genus, based on similarities. The similarity of species is judged based on comparison of physical attributes, and where available, their DNA sequences.All species are given a two-part name, a binomial name, or just binomial.The first part of a binomial is the generic name, the genus to which the species belongs.he second part is either called the specific name (a term used only in zoology) or the specific epithet (the term used in botany, which can also be used in zoology). For example, Boa constrictor is one of four species of the Boa genus. While the genus gets capitalized, the species name does not.

DNA replication In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. This process occurs in all living organisms and is the basis for biological inheritance. DNA is made up of a double helix of two complementary strands. During replication, these strands are separated. Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication.

Hybridization the crossing of organisms differing in heredity—that is, in one or more pairs of alleles (conditions of genes) and consequently in one or more pairs of traits and properties. The crossing of individuals belonging to different species or even to less closely related taxonomic categories is called distant hybridization.

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.

DNA Replication and Repair DNA Replication is Semi-Conservative. DNA replication of one helix of DNA results in two identical helices. If the original DNA helix is called the parental DNA, the two resulting helices can be called daughter helices.Each of these two daughter helices is a nearly exact copy of the parental helix (it is not 100% the same due to mutations).he first step in DNA replication is the separation of the two DNA strands that make up the helix that is to be copied. DNA Helicase untwists the helix at locations called replication origins. The replication origin forms a Y shape, and is called a replication fork.

What does DNA mean? DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide.Nucleotides are arranged in two long strands that form a spiral called a double helix.NA is a double helix formed by base pairs attached to a sugar-phosphate backbone. DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms.

DNA Synthesis Background. Deoxyribonucleic acid (DNA) synthesis is a process by which copies of nucleic acid strands are made. In nature, DNA synthesis takes place in cells by a mechanism known as DNA replication.Using genetic engineering and enzyme chemistry, scientists have developed man-made methods for synthesizing DNA. The most important of these is poly-merase chain reaction (PCR).he order in which the nucleotides are linked, called the sequence, is determined by a process known as DNA sequencing. In a eukaryotic cell, DNA synthesis occurs just prior to cell division through a process called replication. When replication begins the two strands of DNA are separated by a variety of enzymes.

PROKARYOTIC CELL ANATOMY: Learning Objectives for this Section. A. DNA Replication in Bacteria. In general, DNA is replicated by uncoiling of the helix, strand separation by breaking of the hydrogen bonds between the complementary strands, and synthesis of two new strands by complementary base pairing (def).Replication begins at a specific site in the DNA called the origin of replication.NA replication is bidirectional from the origin of replication (see Fig. 12). To begin DNA replication, unwinding enzymes called DNA helicases (def) cause the two parent DNA strands to unwind and separate from one another at the origin of replication to form two Y-shaped replication forks (def).

recombination recombination. Recombination in meiosis. Recombination is a process by which pieces of DNA are broken and recombined to produce new combinations of alleles. This recombination process creates genetic diversity at the level of genes that reflects differences in the DNA sequences of different organisms.In eukaryotic cells, which are cells with a nucleus and organelles, recombination typically occurs during meiosis.s a result, offspring can have different combinations of genes than their parents. Genes that are located farther apart on the same chromosome have a greater likelihood of undergoing recombination, which means they have a greater recombination frequency.

THE BASIS OF DNA TECHNOLOGY Fragments of DNA that have desired genes are isolated to form recombinant DNA for use in a host. All the DNA from a desired organism is isolated to form recombinant DNA for use in a host. Different sections of DNA from a desired organism are inserted into a host so that beneficial traits will be expressed. One strand of DNA is isolated and inserted into a host so recombinant DNA can be formed. Fragments of DNA that have desired genes are isolated to form recombinant DNA for use in a host. Scientists have recently modified the bacteria that cause tooth decay by inserting a fragment of DNA into the bacteria's DNA that prevents it from producing lactic acid.
