It would be UGCCAG. This is because in mRNA, thymine is replaced by Uracil. That means the complementary base pairings are uracil and adenine (instead of thymine and adenine in DNA) and cytosine and guanine. So you need to change them to the other base in the pair. Meaning A (adenine) becomes the base it is paired with, being Uracil in this case and so on.
Sedimentary rocks are 'built up' over time, and if something dies overtime, lets say an animal, it will get buried and minerals will fill it and it becomes a fossil. fossils are important because they tell us about the past and what is was like way back when.
