A fragment of DNA is called recombinant if: it has been amplified using the polymerase chain reaction. it contains DNA sequences from more than one source. It separates using an electric field. when separated by heat, it will anneal on cooling. it is acted upon by spliceosomes and the introns are excised. What does the central dogma specify? Genes are encoded in the nucleus. A DNA sequence encodes an mRNA sequence that encodes a protein. mRNA sequences encode DNA, which encode for proteins. mRNA plays a major role in gene expression. An mRNA sequence encodes protein that encodes DNA.
DNA and RNA
Deoxyribonucleic acid (DNA) is usually called the blueprint of life. Deoxyribose is a monosaccharide that has a key function in the synthesis of deoxyribonucleic acid. One less oxygen-containing hydroxyl group occurs in deoxyribose sugar. Nucleic acid, deoxyribonucleic acid, is one of the natural components. Deoxyribonucleic acid is a double-stranded molecule. Watson and Crick postulated the double-stranded model of the helix. A deoxyribonucleic acid is a molecular group that carries and transmits genetic information from parents to offspring. All eukaryotic and prokaryotic cells are involved.
DNA as the Genetic Material
DNA, or deoxyribonucleic acid, is a long polymeric nucleic acid molecule discovered in the late 1930s. It is a polymer; a long chain-like molecule made up of several monomers connected in a sequence. It possesses certain characteristics that qualify it as a genetic component. Certain organisms have different types of nucleic acids as their genetic material - DNA or RNA.
Genetics
The significant branch in science which involves the study of genes, gene variations, and the organism's heredity is known as genetics. It is also used to study the involvement of a gene or set of genes in the health of an individual and how it prevents several diseases in a human being. Thus, genetics also creates an understanding of various medical conditions.
DNA Replication
The mechanism by which deoxyribonucleic acid (DNA) is capable of producing an exact copy of its own is defined as DNA replication. The DNA molecules utilize a semiconservative method for replication.

Recombinant DNA is the piece of DNA fragment, which were produced by atleast two or more fragments from different sources, to produce hybrid. This technique involves inserting segment of DNA (from one organism) into the chromosome of other organism, with the help of enzymes restriction endonuclease and ligase. Restriction endonuclease recognize specific sequence of DNA and cuts within or near close to sequence. Ligase enzyme joins the restricted fragment to the new restricted site of other organism
