Answer :
Scientists have recently modified the bacteria that causes tooth decay by inserting a fragment of DNA into the bacteria's DNA that prevents it from producing lactic acid. The new DNA is called recombinant DNA.
What is DNA?
DNA is defined as deoxyribonuclic acid and it is a polymer made up of two polynucleotide chains that arranged in foiled structure to form a double helix carrying genetic information for the various processes such as growth development functioning and reproduction.
There are four nitrogen bases of DNA nucleotides are such as adinine, thymine, guanine and cytosine.
Friedrich miescher discovered DNA in the year of 1860.Scientists have recently modified the bacteria that causes tooth decay by inserting a fragment of DNA into the bacteria's DNA that prevents it from producing lactic acid. The new DNA is called recombinant DNA.
The main function of DNA is to carry information from one generation to another generation this is the reason due to which DNA is also known information molecule.
In our body DNA is found in the nucleus of the cell and it is known as nuclear DNA.
The shape of DNA is double helical structure.Scientists have recently modified the bacteria that causes tooth decay by inserting a fragment of DNA into the bacteria's DNA that prevents it from producing lactic acid. The new DNA is called recombinant DNA.
Siblings share only about 50% of same DNA due to the reason of recombination.
