1:Deoxyribonucleic acid

Deoxyribonucleic acidDNA: Deoxyribonucleic acid. One of two types of molecules that encode genetic information. (The other is RNA. In humans DNA is the genetic material; RNA is transcribed from it. In some other organisms, RNA is the genetic material and, in reverse fashion, the DNA isIn biology,

2.a gene (from Greek, meaning generation) is a basic unit of heredity and a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. ... These alleles encode slightly different versions of a protein, which cause different phenotypical traits. transcribed from it.)

3.A protein is a naturally occurring, extremely

complex substance that consists of amino acid residues joined by peptide bonds. Proteins are present in all living organisms and include many essential biological compounds such as enzymes, hormones, and antibodies.

4.A nucleotide is the basic building block of nucleic acids. RNA and DNA are polymers made of long chains of nucleotides. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.

5.one haploid set of chromosomes with the genes they contain broadly : the genetic material of an organism — compare proteome.
