Answer:
A) A mutation in a single gene can result in a defective protein.
Explanation:
This hypothesis states that one gene codes for one protein-enzyme, so consequently, if mutation occurs in that gene, the enzyme will not work properly. This hypothesis was very important for the fundamental discoveries of molecular biology, but it is oversimplified meaning that relationship between genes and proteins is much more complex.
The epidermis is the outermost layer of skin and is app. .005-1.5mm thick. it is made up of several different types of cells with keratinocutes being the most abundant.
The dermis is the second layer of skin and is app. .3-3.0mm thick. And basically consists of connective tissue.
The manufacture and characterisation of silver oxide films for application as bactericidal coatings are described in the research.
- There are reports on the synthesis parameters, dissolution/elution rate, and bactericidal effectiveness.
- Reactive magnetron sputtering was used to generate the synthetic conditions necessary to produce AgO, Ag2O, or combinations of AgO and Ag2O on surfaces.
- All of the examined bacterial strains are hampered from growing by the coatings, which exhibit good adherence to numerous substrate materials.
- <em>Escherichia coli</em> and <em>Staphylococcus aureus</em> can be killed by the coatings, which also show a distinct zone of inhibition against bacteria growing on solid media and the capacity to quickly stop bacterial growth in planktonic culture.
