artificial synthesis of dna

Artificial Synthesis of DNA on Template - In 1961, Kornberg and his coworkers synthesized DNA from a mixture of deoxyribonucleoside triphosphates, DNA polymerase enzyme, metal ions and a segment of viral DNA functioning as a primer. The sy..

In 1961, Kornberg and his coworkers synthesized DNA from a mixture of deoxyribonucleoside triphosphates, DNA polymerase enzyme, metal ions and a segment of viral DNA functioning as a primer. The synthetic DNA showed biological activity. When introduced ..

DNA serves the following functions. It is the genetic material in all prokaryotes and eukaryotes. It is capable of replication by which it can be faithfully passed on to successive generations. It is involved in the synthesis of RNA. It provides the code for protein ..

Protein synthesis requires amino acids, DNA, RNAs, ribosomes and enzymes, enzyme activators and ATP molecul..

One GTP is hydrolysed to GDP as each successive amino acid-tRNA complex attaches to the A site of the ribosome. A second GTP is broken down to GDP as the ribosome moves to each new codon in the mRNA. One ATP is hydrolysed to AMP during amino acid activation. Thus, the formation of each peptide bond..

Mechanism of DNA Replication - It is a complex process and involves the participation of over a dozen enzymes and other protein factors. The intertwined DNA starts separating from a particular point and this is known as the origin of replication. The second step is that the two ..

The histone coat protecting the DNA double helix of the gene to be transcribed is removed, on a signal from the cytoplasm, exposing the polynucleotide sequences in this region of DNA. The RNA polymerase enzyme binds to a specific site, called promoter, in the DNA doubl..

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 ..
