The expected frequency of restriction site 5'GGCC-3' is once every 256 nucleotides. This is because the recognition sequence of the given restriction site is 5'-GGCC-3' in genome lets assume that the nitrogen bases are independent in recognition sequence.
Total types of nucleotides in DNA is four which is thymine, cytosine, guanine, adenine.
Total frequency of any sequence of "n" nitrogen bases is 1/4n where n is for nitrogen bases or GGCC.
Therefore the frequency is 1/4×4 which is equal to 1/256 is equal to once every 256.
Answer:
Irradiation is way of preventing food-borne diseases without affecting the taste and nutrient content of foods like lettuce and other vegetables.
Explanation:
Food irradiation is the process of applying ionizing radiation to food. It is a technology that enhances the safety of foods by removing or destroying microorganisms and insects present in food.
Irradiation serve as a way of preservation which can extend the shelf life of food and delay ripening by killing or inactivate organisms that cause spoilage and decomposition.

Explanation:
Any material from which energy can be obtained is called a fuel.
There are three types of fuel:
1. Bio-fuel: Fuels that are made from the seeds of various plants. Example, sunflower seeds, groundnut seeds, etc.
2. Nuclear fuel: Radioactive elements like uranium 238 decay to form elements of lower atomic numbers. This is called fission. The process releases a lot of energy.
3. Fossil fuels: Coal, petrol, diesel, gasoline, etc are the common fossil fuels that we use in our vehicles or for heating the interiors of homes.
4. Batteries: These store the electrical energy in them. They are used to power toys, modern vehicles, indoor lighting, etc.
5. Biological compounds: ATP, GTP, various sugar molecules, etc.
