The amino acid sequence of a portion of a polypeptide is
-glu-met-tyr-trp-lys-.
i just need with part c
a. determine the mrna sequence encoding this polypeptide fragment. 5'-g-g-n-g-a-pu-a-u-g-u-a-py-u-g-g- a-a-pu-g-c-n-3'
b. determine the dna template strand sequence corresponding to the mrna above. 5' n-g-c-py-t-t-c-c-a-pu-t-a-c-a-t-py- t-c-n-c-c- 3'
c. determine the dna coding strand sequence corresponding to the template strand above.
express your answer as a sequence of nucleotides separated by dashes. use n to represent any nucleotide (a, t, c or g), pu to represent a purine( a, g), and py to represent a pyrimidine (c, t). example: c-t-pu-n-.

there’s no image attached but i can if you want: )

what are the options? add them, then i will be glad to .

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
