DNA

16 September, 2018

Everyone has DNA. They get their DNA from their family, there is some DNA from your father and some from your mother.

Do you know what DNA is? Well here’s the answer :

Deoxyribonucleic acid, more commonly known as DNA, is a complex molecule that contains all of the information necessary to build and maintain an organism. All living things have DNA within their cells. In other words, whenever organisms reproduce, a portion of their DNA is passed along to their offspring. The first person to discover DNA was James Watson and Francis Crick.

Do you know what happens to the DNA when a person dies?

Well here’s the answer, nothing special; but like other molecules in the body after death DNA starts degrading as per the environmental conditions. DNA is a more stable molecule and can stay longer than proteins and lipids; but slowly that also starts degrading due to lysosomes attack, degradation of cell physiology and pH to form different monomers like phosphates, nitrogen, sugar and carbon, to get absorbed by other life forms and make some other useful molecules.

I hope you learnt something from this, DNA lesson.
