what is biotechnology dna

Genetic engineering can be described as an in vitro manipulation of genes. It refers to artificial synthesis, modification, removal, addition and repair of the genetic material (DNA) to alter the genotype at will. It has evoked great interest because it may enable the geneticists in..

A gel is immersed in a buffered solution, and then DNA fragments from individuals are added to the gel. When an electric current is applied to the solution, one end of the gel takes on a negative charge, and the other end a positive charge. DNA molecules carry a negative charge ..

The technique of finger printing was perfected by British genetist Dr. Alec Jeffreys in 1984. fig. 25.9 Identical Twins No two people (other than identical twins) have exactly the same sequence of bases in their DNA. By detecting these, the differences in DNA sequences, it is po..

It is the DNA that is transferred from one organism into another by combining it with the vehicle DNA. Three types of DNA are used as passengers: complimentary, synthetic and ran..

Replication of DNA - The most significant feature of DNA molecule is its capacity to make its own identical copies. This property is called replication. It occurs regularly during the synthetic phase of the cell cycle, every time a cell divides. During replication, the DNAh..

DNA molecule is a double helical structure made of deoxyribo nucleotides. RNA is also present in nucleus as well as cytoplasm. DNA is the major source of genetic information which is copied into RNA molecules (transcription). The sequence of nucleotides contains the 'code' for ..
