What is DNA
Inside the cell is the chromosome, which unravels and shows the DNA. DNA is 2 strands connected with nucleotides. A gene is segment of DNA.

What is a gene?: A gene is the basic unit of inheritance for a given characteristic. they always exist in pairs and are considered as the main factors that determined the characteristics of all organism

Only one pair of these factors can be represented in a single gamete.

In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function.

What is DNA?

Deoxyribonucleic acid is a molecule composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids. The successful approach of bringing out the structure of a DNA molecule was put forward by James Watson and Frances Crick in which they brought the ideal that a DNA molecule may be a double-helical chain of polynucleotide held together by primary of bases by Hydrogen bonds, between neighbouring chains. Also, Watson and crick, therefore, illustrate that a DNA molecule consists of two polypeptide chain coiled around each other to form a double helix. the chains run anti-parallel to each other in the 5″ —3″ direction. they are said to be complementary.
