Use your codon chart and tell me what amino acids are coded for by the mRNA sequence AUG CGG UCC GGA

Methionine, arginine, serine, glycine  

Explanation:

Use a codon chart (attached below) to determine what amino acids are coded for by the strand of mRNA. Remember that codons are groups of three nucleotides in mRNA. So, read the nucleotides in groups of three (just as how they are separated by spaces) and from left to right.  

To use this codon chart, identify the first letter representing the first nucleotide in the codon. Then, find the matching letter that's one of the four biggest letters in the middle of the chart. Identify the second letter, then find the matching medium letter in the chart, staying within the section of the first letter as indicated by the lines, and do the same process with the third. Repeat for each codon.

Thus, with this mRNA strand, the amino acids will be methionine, arginine, serine, glycine.

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.
