Answer:
The correct answers are: Dilution factor = 250 and concentration of DNA in undiluted sample = 2.5 μg/μl.
Explanation:
- Volume of DNA taken = 2 μl.
- Volume of added water = 498 μl.
- Total volume of the sample = 2 μl + 498 μl = 500 μl.
- Dilution factor =
- A₂₆₀ of the given sample is = 0.2.
- We know that 50 μg/ml concentration of pure double stranded DNA gives an absorbance, A₂₆₀ = 1.
- Again, Concentration of DNA(µg/ml) =
µg/ml. - =
μg/ml. - In order to convert it into μg/μl, we have to divide the above value by 1000, hence we get,
μg/μl.
Answer:
The correct answer is - true.
Explanation:
The scientific journal is are the journals that publish the recent scientific findings or scientific experiments that produce new and appropriate results regarding particular experiment or research/
To confirm an experiment, published finding must be tested repeatedly by different scientists and researchers and see if the results are same in particular conditions.
Thus, the correct answer is - true.
They make up everything needed to create DNA, although im not very sure, i think the answer your looking for is DNA.
Answer:
The picture given displays an ecosystem's food chain. The animals are the organisms that the energy flows through and the arrows represent where the enerrgy is going.
