Answer:
In the transcription of DNA to mRNA, for the DNA sequence 3'-AGGTCTCAC-5' corresponds to an mRNA sequence 5'-UCCAGAAGUG-3'.
Explanation:
Transcription is the process by which a strand of mRNA, needed to direct protein synthesis in the cytoplasm, is synthesized from a strand of DNA.
The sequence of nucleotides in the RNA chain depends on the sequence of bases in the DNA strand, being placed according to the complementarity of nitrogenous bases, where a purine is complemented with a pyrimidine.
In RNA, the thymine base is replaced by Uracil, the complementary base to adenine of DNA.

For this reason:

Answer:
According to the case history, Mrs.Wharton is a 59-year-old woman who presented in the dermatologist's office with a complaint of changes in a mole or a<u> nevus.</u>
Explanation:
The correct answer to complete the sentence is the term "nevus". A nevus (plural:nevi) is the medical term for the word mole, which in most occasions is what patients will use to describe the condition. A nevus or mole are the product of a collection of colored cells, and are very common among people, with the average of 10 to 40 nevi per person. Although most nevus are harmless in their nature, it is important for everyone that has one to check them regularly, and in the case that the person sees a change in the appearance of the nevus he/she should go to the doctor's office for a medical examination, just like Mrs. Wharton did.
