The answer is the second option namely CCGATC. This is because of the inclusion of T for thymine. RNA never has thymine in its structure but thymine is always replaced with uracil. In RNA, thymine is replaced by uracil as the base complementary to adenine. Uracil is very similar to thymine and is energetically less expensive to produce than thymine which may account for its use in RNA. In DNA however, uracil is readily produced by chemical degradation of cytosine so having thymine which is more stable than uracil in that respect makes it more ideal to have in the DNA structure because it has a higher fidelity than uracil.

This is s cute awee : (( . well if she's showing you signs that she may like you , then shoot your shot ! don't be afraid . & if you're unsure that she's giving you these signs , then wait out for a little bit . most girls are different . some may act really sweet , but only bc you're a good friend of hers . that , or she might like you . you just never know . but i think you should sit down with her & tell her how you feel . but don't be awkward & shy . just be straight up & tell her how you feel . if the feelings aren't mutual , then don't cry about it . you need to respect her decision & look for others in the world . feelings can be difficult & confusing , but don't be afraid to show them . i say you play it out & if you're still unsure about it , talk to her . - rach
