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.

Answer:
B. He has no E alleles.
Explanation:
In order for the boy to have an attached earlobes phenotype, he must have no E alleles, because the E is dominant. So his genotype must be ee. If he has even just a single E allele (like Ee) he will have detached earlobes, because the dominant trait will mask the expression of the recessive trait.
Why not A or D: Heterozygous Ee (one of each allele) would result in detached earlobes.
Why not C: If he has no recessive alleles, EE, he would have detached earlobes.
The cell membrane is made of a protein layer that is sandwiched between 2 phospolipid layers. It has pores that allow selective passage of substances in and out of the cell.
