Experiments such as the one by Frederick Griffith in 1928 showed that DNA is the hereditary molecule. How showed that virulent bacterial species could transfer DNA to avirulent species and make them virulent too. This means that DNA determines the characteristic of the individual and can be passed down or across generations.
Molecule which called the molecule of hereditary is DNA, or deoxyribonucleic acid,the hereditary material in humans and almost all other organisms,Most DNA is located in the cell nucleus.
<u>Explanation:</u>
The genetic information that make persons are different from each other and transform from parents to offspring by a process called heredity, this information stored in DNA as a code made up of four chemical bases:
adenine (A)
guanine (G)
cytosine (C)
thymine (T)
DNA bases pair up with each other to form units called base pairs:
A with T
C with G
Each base is also attached to a sugar molecule and a phosphate molecule.
Base+ sugar molecule+phosphate= Nucleotide.
The DNA is consists of nucleotide that arranged in two long strands that form a spiral called a double helix as in figure
DNA can replicate (make copies of it self), and this is very important during cell division, because the new cells need to have new DNA.

A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. ... To identify a chemical property, we look for a chemical change.
DNA contain the instructions of the traits of an organism. Most of the organism have the same DNA but what makes each different is the sequence of the DNA. The sequence gives the instructions for the production of amino acid that will produce, which in turn determines what traits will be passed on or manifested by that individual.
A promoter is a region of DNA where transcription of a gene is initiated. Promoters are a vital component of expression vectors because they control the binding of RNA polymerase to DNA. RNA polymerase transcribes DNA to mRNA which is ultimately translated into a functional protein.
