Well, considering that seagulls, bears, and cows are warm blooded mammals, and spiders are arachnids with an exoskeleton, I'm willing to bet that spiders are ectothermic. And isn't the word exothermic?

Answer:
The answer to your question is ACUCTTCUGGUCCCAACA
Explanation:
Base sequence 
                          TGAGAAGACCAGGGTTGT
Nitrogenous bases change from DNA to RNA
                    DNA                      RNA
                       Adenine                 Uracil
                       Thymine                  Adenine
                       Guanine                 Cytosine
                       Cytosine                 Guanine
Then from left to right, the new sequence the RNA is
                         
                            ACUCTTCUGGUCCCAACA
