Yes and no, while it is much better to take out your piercings during X-ray it won’t harm you if you don’t. After doing some reading from what I gather is it just creates a black image blocking what they could be looking for. All you really need to remove is the piercings that are in the way.
The answer is UAC.
In the RNA, base complements are adenine - uracil (A-U) and guanine -cytosine (G-C). So, when in the process of translation, anticodons of tRNA pairs with codons of mRNA, the complementary bases will pair. So, adenine in tRNA will pair uracil in mRNA (A → U), uracil in tRNA will pair adenine in mRNA (U → A), and guanine <span>in tRNA will pair cytosine in mRNA (G </span>→ C):
tRNA: A U G
mRNA: U A C
It is an advantage because they approach their environments from all sides equally.
