PCR is an enzymatic process in which a specific region of DNA is replicated over and over again to yield many copies of a particular sequence. The most widely used … Read more
Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). In prokaryotic organisms transcription occurs in three phases … Read more
DNA replication is the process by which an organism duplicates its DNA into another copy that is passed on to daughter cells. Replication occurs before a cell divides to ensure that … Read more
Pulsed Field Gel Electrophoresis (PFGE) is a technique used for the separation of large deoxyribonucleic acid (DNA) molecules by applying to a gel matrix an electric field that periodically changes … Read more
DNA transcription, also known as RNA synthesis is the process by which genetic information that is contained in DNA is re-written into messenger RNA (mRNA) by an RNA polymerase enzyme. The … Read more

What is RNA? Its full form is Ribonucleic acid. This is a polymer of subunits joined by phosphodiester bonds. It is a single-stranded nucleic acid similar to DNA but having … Read more
Restriction Enzyme (Restriction Endonuclease) Definition Restriction enzyme, also called restriction endonuclease, is a protein produced by bacteria that cleaves DNA at specific sites along the molecule. Restriction endonucleases cut the DNA double helix in very … Read more
DNA microarrays are solid supports, usually of glass or silicon, upon which DNA is attached in an organized, pre-determined grid fashion. Each spot of DNA, called a probe, represents a … Read more
