Remember that each amino acid change is caused by a single nucleotide substitution. use this information to further limit the possible codons for each amino acid. which of the following codons could still code for arginine (arg)? select all that apply. agaaggcgacgc cgg cgu

The answer to your question is: first two.

Explanation:

Codons that code for Arginine   AGA and AGG

Then,

                  AGA AGG CGA CGC  CGG  CGU

The first two codons will code for Arginine

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
