Question

What is the origin of DNA?

Answer 1

DNA:

1. DNA is a molecule that is in charge of transporting and transferring hereditary contents or genetic instructions from parents to children.
2. Nucleic acids, sometimes known as DNA or RNA, are chemical molecules found in all living things.
3. These nucleic acids are built up of a sequence of connections that connect nitrogenous bases, sugar molecules, and phosphate groups.

Origin of DNA:

1. The DNA structure establishes our body's fundamental genetic composition. In fact, it defines practically all life on Earth's genetic composition.
2. Apart from being responsible for the transmission of genetic information in all living things, DNA is also involved in the creation of proteins.
3. The Swiss researcher Johannes Friedrich Miescher discovered and identified DNA in 1869 while studying white blood cells.
4. Scientists believe that the progenitors to DNA and RNA were basic chemical molecules capable of replication and natural selection.
5. DNA and DNA replication processes developed late in the evolution of life, and DNA evolved from RNA in an RNA/protein environment.
6. The development of U-DNA was most likely the earliest stage in the evolution of DNA (DNA containing uracil).
