What would be the mRNA complementary base sequence for a DNA strand that is: A  C G G T C<br>​
Alina [70]
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.

Increased atmospheric carbon dioxide negatively affects coral reefs by: select one:
Ksenya-84 [330]
Increased atmospheric carbon dioxide will diffuse to the ocean water (since normally, there is lower concentration of dissolved carbon dioxide in the ocean water). The dissolved carbon dioxide takes into the form of carbonic acid thereby increasing acidity of ocean water. More often than not, the acidification of ocean water leads to detrimental results especially in marine organisms that are pH sensitive such as coral reefs and many invertebrates.
