Explanation:
Given -
Half life of the silicon-32 years
Half life means the time period required by a radioactive element to reduce its mass by half.
Radioactive decay formula is
Where
A represents the amount of radioactive element after time t years
represents the initial amount of radioactive element
time of decay
half-life of the substance
Substituting the given values in above equation, we get -
grams
Answer:
In order to make E. coli bacterial cells glow green, we need to insert a gene that can be translated into the <u>green fluorescent protein.</u> This gene is well-known as <u>gfp</u> and can be inserted either in the DNA or plasmid of the bacteria. The genome insertion procedure would follow the conventional method where the DNA will be first cut using restriction enzymes and then would be ligated. This approach has been extensively applied to test the fate of bacteria in the environmental systems.
A schematic diagram on insertion of gfp in the plasmid of bacteria is shown in the figure. The left side diagram shows that gfp is inserted and right side figure shows glowing bacteria in the presence of UV.
