Answer:
A to N
Explanation:
Glutamine is an amino acid with a polar, uncharged side chain. The mutation to alanine, an amino acid with a non-polar side chain, completely affects the enzymatic activity. This makes sense considering the difference in the nature of both amino acids.
To restore the wild-type level of activity the alanine would have to mutate to another polar uncharged amino acid. Among the given options, only Asparagine (N) has a similar chemistry to Glutamine.
Answer:
![D=5.89\times 10^{12}\ km](https://tex.z-dn.net/?f=D%3D5.89%5Ctimes%2010%5E%7B12%7D%5C%20km)
Explanation:
The distance to the Sun is 5,890,000,000,000. We need to write this distance in km.
A number can be written as
in scientific notation where x is a real no and y is any integer.
There are 10 zeros in the given number and also there are 12 digits after. It would mean that,
![D=5.89\times 10^{12}\ km](https://tex.z-dn.net/?f=D%3D5.89%5Ctimes%2010%5E%7B12%7D%5C%20km)
So, the distance in scientific notation is : ![D=5.89\times 10^{12}\ km](https://tex.z-dn.net/?f=D%3D5.89%5Ctimes%2010%5E%7B12%7D%5C%20km)
