Introduction of recombinant DNA into a suitable host

recombinant-dna-technology-hourlybook

A. Increase competence of host for transformation • Competent host is essential for transformation with the recombinant DNA. Transformation is a process by which a cell takes up the naked DNA fragment from its environment, incorporates it into its own chromosomal DNA, and finally expresses the trait controlled by the incoming DNA. • Finally, the … Read more Introduction of recombinant DNA into a suitable host

Characteristics of a cloning vector in Recombinant DNA Technology

Origin of replication (Ori) • This is a specific sequence from where replication starts, when any piece of foreign DNA is linked to this sequence. • The replication occurs inside the host cells. This sequence is also responsible for controlling the copy number of linked DNA. • A prokayotic DNA has single origin of replication, … Read more Characteristics of a cloning vector in Recombinant DNA Technology

Enzymes in Recombinant DNA Technology

Different kinds of specific enzymes are used in genetic engineering (recombinant DNA technology). These include lysing enzymes, cleaving enzymes, synthesizing enzymes, joining enzymes and alkaline phosphatase. • The palindromes in DNA are base pair sequences that are the same, when read forward (left to right) or backward (right to left), from a central axis of … Read more Enzymes in Recombinant DNA Technology

AIPMT PMT – Biotechnology – Principles and Processes

Biotechnology • The term biotechnology is derived from a fusion of biology and technology. Biotechnology means any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use. • Berg is often considered “Father of genetic engineering”. He was awarded Nobel Prize in 1980. • … Read more AIPMT PMT – Biotechnology – Principles and Processes

4 Top Issues with Applications of Biotechnology

Following are the issues related to applications of Biotechnology: Ethical Issues: Ethics include a set of standards by which a community regulates its behaviour and decides as to which activity is legitimate and which is not. Therefore, bioethics may be viewed as a set of standards that may be used to regulate our activities in … Read more 4 Top Issues with Applications of Biotechnology

Transgenic Animals

Animals that have had their DNA manipulated to possess and express an extra (foreign) gene are known as transgenic animals or Genetically Engineered Animals. Various applications of transgenic animals are: • Study of normal physiology and development: Transgenic animals can be specifically designed to allow the study of how genes are regulated, and how they … Read more Transgenic Animals

Applications of Biotechnology in Medicine

The recombinant DNA technological processes have made great impact in the area of healthcare by mass production of safe and more effective therapeutic drugs. A large number of human genes encoding pharmaceutically valuable proteins have been cloned and expressed in microorganisms largely employed by biotech pharmaceuticals. Initially, E. coli was used as the host for … Read more Applications of Biotechnology in Medicine

Biotechnology and its applications

Biotechnology is the use of living systems and organisms to develop or make useful products. It harnesses cellular and biomolecular processes to develop technologies and products that help improve our health and lives. Modern biotechnology provides breakthrough solutions and technologies to combat debilitating and rare diseases, reduce our environmental footprint, feed the hungry, use less … Read more Biotechnology and its applications
