A report on DNA
Polymer 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.

RNA
44 linksPolymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes.
Polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes.
RNA and deoxyribonucleic acid (DNA) are nucleic acids.
Gene
47 linksIn biology, a gene (from γένος, ; meaning generation or birth or gender) 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.
Protein
36 linksProteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues.
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues.
Because DNA contains four nucleotides, the total number of possible codons is 64; hence, there is some redundancy in the genetic code, with some amino acids specified by more than one codon.
Base pair
27 linksFundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds.
Fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds.
They form the building blocks of the DNA double helix and contribute to the folded structure of both DNA and RNA.
Nucleic acid
27 linksNucleic acids are biopolymers, macromolecules, essential to all known forms of life.
Nucleic acids are biopolymers, macromolecules, essential to all known forms of life.
The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Nucleotide
26 linksNucleotides are organic molecules consisting of a nucleoside and a phosphate.
Nucleotides are organic molecules consisting of a nucleoside and a phosphate.
They serve as monomeric units of the nucleic acid polymers – deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all life-forms on Earth.
DNA replication
26 linksIn molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule.
Bacteria
29 linksBacteria (singular bacterium, common noun bacteria) are ubiquitous, mostly free-living organisms often consisting of one biological cell.
Bacteria (singular bacterium, common noun bacteria) are ubiquitous, mostly free-living organisms often consisting of one biological cell.
Bacteria do not have a membrane-bound nucleus, and their genetic material is typically a single circular bacterial chromosome of DNA located in the cytoplasm in an irregularly shaped body called the nucleoid.
Virus
20 linksSubmicroscopic infectious agent that replicates only inside the living cells of an organism.
Submicroscopic infectious agent that replicates only inside the living cells of an organism.
When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles, or virions, consisting of (i) the genetic material, i.e., long molecules of DNA or RNA that encode the structure of the proteins by which the virus acts; (ii) a protein coat, the capsid, which surrounds and protects the genetic material; and in some cases (iii) an outside envelope of lipids.
Chromosome
19 linksA chromosome is a long DNA molecule with part or all of the genetic material of an organism.
