Give two reasons why studying DNA is important.

DNA is vital for all living beings – even plants. It is important for inheritance, coding for proteins and the genetic instruction guide for life and its processes. DNA holds the instructions for an organism's or each cell's development and reproduction and ultimately death.

Explanation:

A scientist has the ability to remove DNA from an organism, they can manipulate, classify, and observe the DNA.

By studying DNA, a scientist can identify genetic diseases or disorders. By experimenting with or manipulating with DNA, the scientist can possibly find cures for the causes.

DNA is a thread-like chain of nucleotides which carries genetic instructions and is used in the growth functioning, reproduction, and development of all many viruses and known living organisms. RNA and DNA are termed as nucleic acids alongside lipids, proteins, and carbohydrates.

RNA and DNA are major types of macromolecules that are essential for well-known forms of life.
