No DNA sequence wont have U (uracil), so it is an RNA sequence!
The mRNA base sequence corresponding to the DNA sequence acgtt is ugcaa. The mRNA sequence is complementary to the DNA sequence, with thymine (T) in DNA being replaced by uracil (U) in mRNA.
in DNA, each base pairs up with only one other base
If the DNA sequence is ACT, the complimentary mRNA sequence would be UGA
You can predict the base seqences of a DNA molecule if you know what one strand is, because of double Stranded DNA. Each strand matches up with a letter and repeats a pattern throught the entire DNA strand.
A complimentary DNA sequence is the genetic code on the partner strand that aligns with and corresponds to (matches) the code on the primary strand. Each nucleotide has a match, A matches T and C matches G, therefore the complimentary sequence for ATCGA is TAGCT.
Restriction enzymes recognize specific sequences of nucleotides in DNA molecules and bind to them. Once bound, the enzyme cuts the DNA at specific points within or near the recognized sequence, resulting in precise cleavage of the DNA molecule.

The sequence of the nitrogenous bases, which are the 'rungs' of the DNA 'ladder' are what give DNA its specificity.
