Answer:
This question is incomplete
Explanation:
This question is incomplete but the completed question can be found in the attachment below.
During protein synthesis, a sequence of three mRNA nucleotides (called codons) correspond to specific amino acids. From the question, the change in guanosine nucleotides will change the sequence as follow
DNA: T--A--C--A--A--C--T--A--C--T--T--C--T--T--T--C--T--T--A--A--A
mRNA: A--U--G|-U--U--G|-A--U--G|-A--A--G|-A--A--A|-G--A--A|-U--U--U
Amino Acids: met -- leu -- met -- lys -- lys -- Glu -- Phe
The new amino acid sequence is represented above from the new DNA sequence.

Some helpful tips:
The nucleus is always going to be the big, spherical shape.
The ER is always going to be a weird, folded looking structure attached to the nucleus (rough = has ribosomes on it which are usually represented by little dots, smooth = has no ribosomes on it aka no dots)
The GA looks like the ER but it is not going to be attached to the nucleus like the ER is.
The mitochondria is always going to be pill-shaped and have weird folds inside of it.
Birds, insects, and many reptiles excrete nitrogenous waste in the form of uric acid, which saves water.
Nitrogenous waste in the body tend to form toxic ammonia, which must be excreted. Mammals such as human excrete urea, while birds, reptiles, and some terrestrial invertebrates produce uric acid as waste in the form of a white paste or power. The production of uric acid involves a complex metabolic pathway that is energetically costly in comparison to processing of other nitrogenous wastes such as urea or ammonia, it has the advantages of reducing water loss and, hence, reducing the need for water.
