This copy, called a messenger RNA (mRNA) molecule, leaves the cell nucleus and enters the cytoplasm, where it directs the synthesis of the protein, which it encodes. Translation is the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis.
DNA repair is a collection of processes by which a cell identifies and corrects damage to the DNA molecules that encode its genome. In human cells, both normal metabolic activities and environmental factors such as radiation can cause DNA damage, resulting in as many as 1 million individual molecular lesions per cell per day. Many of these lesions cause structural damage to the DNA molecule.
The antibiotic age was ushered in with the accidental discovery of penicillin by Alexander Fleming (1881-1955) in 1928. Even though it was over ten years before mass production of penicillin was achieved, a new era had arrived.

Mechanisms of RNA Polymerases. Synthesis of RNA exhibits several features that are synonymous with DNA replication. RNA synthesis requires accurate and efficient initiation, elongation proceeds in the 5′ → 3′ direction (i.e. the polymerase moves along the template strand of DNA in the 3′ → 5′ direction), and RNA synthesis requires distinct and accurate termination.

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. The transmission of genes to an organism’s offspring is the basis of the inheritance of phenotypic trait.
mRNA is “messenger” RNA. mRNA is synthesized in the nucleus using the nucelotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.
In a cell, DNA replication must happen before cell division can occur. DNA synthesis begins at specific locations in the genome, called "origins", where the two strands of DNA are separated.
