Some of the exogenous agents capable of causing DNA damage are ultraviolet rays and ionising radiation, environmental toxins, e.g., polycyclic aromatic hydrocarbons (PAHs) and heavy metals, and chemicals used in chemotherapy of cancers. The types of DNA damage caused include covalent modification of the four bases (A, T, G and C) in DNA, single- and double-stranded breaks in the DNA backbone, mismatch of base pairing occurring during DNA replication, and intrastrand and interstrand crosslink formation between DNA bases.

In general terms this was to introduce concepts related to enzyme kinetics. Introduction Enzymes are among several proteins generated in living cells to catalyze or accelerate the organism’s metabolic processes. Normally, enzymes are so selective and specific on the molecules they catalyze, referred to as substrate (Dixon, 1979).They normally do react specifically with a single substrate.

When the material is pulled, one would be able to establish the strength of the material. In this regard, tensile testing can help one to develop an insight into various substances. Whenever one continues to pull on a material, the material will break hence one would get a recommendable profile of tensile.

Chlorine will have the tendency to form the anion, Cl-. There will be no sharing of electrons, hence giving rise to an ionic bond. Iodine is in Group VII and has 7 electrons in its outer shell, one of them being unpaired. A single bond will be formed between two iodine atoms, with an equal sharing of these two outer shell electrons.
